Techlog) displayed in the Project browser
You can select to display the family name and unit and sort the
objects in ascending or descending order.

Procedure 1 Filtering Data in the Project
Browser
You can filter the data displayed in the Project browser to show
only what you want to view. After you apply a filter, only the
elements matching the filter criteria are displayed and the Project
browser changes color.
There are two methods in Techlog for managing filters. This
procedure shows you how to filter data by using the Filter tab or
the Create a filter menu command.
1. In the Project browser Properties window, open the
Filter tab and select the filter criteria for these options:
• Well: Apply a filter with a specific well name, or with the last
modification date or date of creation.
• Dataset: Apply a filter with a specific data set name,
sampling, last modification date, date of creation, or type.
You can make several selections at one time.
• Variable: Apply a filter with a specific variable name, main
family, family, unit, version status, last modification date,
type, or description. You can make several selections at one
time.
• Group: Apply a filter with a group name.
Common operators are AND (&) and OR (|), but you also can
use an asterisk (*).

NOTE: More information about the syntax can be found in
the Techlog Help file.

2. Alternatively, select variables, wells, and data sets in the
Project browser, right-click and select Create a filter.
The variable, data set, or well selected is updated in the
Project browser Properties window.

After a filter is created, the Project browser changes color
and only the variables, data set, and wells selected by the
filter are displayed.
3. Remove a filter by right-clicking in the Project browser and
selecting Remove the current filter.

Procedure 2 Applying Conditional Selections
Conditional selection is an option that allows you to select one or
several curves, wells, or data sets. For example, you can use this
option to select specific curves to drag into a LogView layout.
Conditional selection is available only in the Project browser.
Similar to the filter option, there are two ways to manage
conditional selection in Techlog, in the Properties window and
with the Conditional selection command.
Conditional selection tab and select the filter criteria for
the Well, Dataset, Variable, and Group options.
The variables, data set, and wells selected by the conditional
selection are highlighted in gray.
2. To remove a conditional selection, click in the Project
browser.
Procedure 3 Grouping Data Objects Manually
You can group wells, data sets, and variables manually according
to the properties available in the wells, data sets, and logs.
Manual grouping is accessed from the Project browser.
1. In the Project browser, select at least two wells, data sets,
or variables.
2. Right-click and select Group.
3. In the window that opens, enter a name for the group and
click OK. The group is created and displayed in the Project
browser.

TIP: You can group any objects in the Project browser.

Procedure 4 Grouping Data Objects
Automatically
You can use the Properties window to group wells, data sets, or
variables automatically.
Grouping tab.

2. Select one of these options for the Display type.
• Techlog: Wells, data sets, and variables are not grouped.
• Hierarchical grouping: Wells, data sets, and variables are
grouped according to wells, data sets, or variables
properties (based on country in the figure in Step 1).
• Project: Wells, data sets, and variables are grouped
according to the user.
3. Enter the grouping criteria.
This figure shows examples of how objects are displayed in
the Project browser based on the display type and grouping
criteria.

Data Search
You can use the search field in the Project browser to quickly
display all the variables or objects that contain the search word
that you enter. In the example shown in Figure 5, the word gamm
is entered as the search criteria and all wells and histograms that
contain a variable named gamm are displayed in the Project
browser.

You can right-click on a well, data set, or a variable to access an
interactive list of the actions available for each Techlog object.
This list of actions is called the contextual menu.
The actions available in the contextual menu depend on the object
you select. You can apply these actions to wells, data sets, and
variables directly from the Project browser.
Figure 6 Contextual menus for a well, data set, and variable
Trash Bin
The trash bin allows you to store data deleted from the Project
browser.
WARNING: Be aware that if data is deleted with the Delete
command, it will be stored in the trash bin and you
can retrieve it. However, if data is deleted with the
Delete definitively command, it cannot be
retrieved.

Output Window
The Output window contains information about every operation
being run in Techlog. These messages provide you with valuable
information and alert you to issues with the applications.
Messages display in one of three colors, depending on the
content of the information.
• Green is for information.
• Orange is a warning.
• Red is for errors.
• Blue is for command lines.
Each error and warning message is documented with an
explanation about why the error or warning occurred. Figure 7
shows a sample green information message.
Figure 7 Information message after importing a data set
Properties Window
The Properties window displays the parameters of any selected
object such as a variable, a workflow, or a log view. The content of
the window depends on the selected object. The window allows
you to edit the properties of the object.

For example, if you select the variable DENS in a layout, the
window will show the display properties of this variable. Figure 8
shows these identifying elements of an object when it is selected
in the Properties window.

properties that are highlighted in green.

Procedure 5 Using the Properties Window
You should keep the Properties window open at all times. You
also can use the F4 shortcut to display the Properties window for
any object in Techlog.
In this procedure, you use the F4 button to make the Properties
window display or not display.
1. Press F4 to bring the Properties window to the front.
NOTE: You can edit the unit of the variable manually.
2. Press F4 again to dock the Properties window in its original
place.
Zonation Window
The Zonation window stores all of the interval sets in the project.
Zones selected in the Zonation window are reflected in plot
displays and workflows.
To select zones, choose the name of the set from the drop-down
list (Figure 10). In this example, only one set, named
STRATIGRAPHY, exists.
Figure 10 Selecting a zonation data set

After you select a data set, a list appears that contains all of the
zones within the zonation set. For example, in a layout, the selected
zones in the Zonation window are highlighted in the layout
(Figure 11).
Figure 11 Zones selected in the zonation window are
highlighted in the LogView display

Markers Manager
The Markers dock window shows you all the markers available in
your project.
• Click on the drop-down menu to select the marker type data
set you want to display.
• Use the Marker pane to select those specific markers you
want to display.
Figure 12 Markers manager
Workspace Manager
The Workspace manager lists the workspaces open in Techlog
and the windows open within each workspace, such as plots and
workflows. Figure 13 shows the active windows and workspaces
displayed in bold.
You can rename and save the workspace. When you reopen the
workspace, the windows will be arranged in the same way as they
were when you saved the workspace.

In Figure 13, the active window is the layout UnknownMW in the
workspace named Techlog workspace.
Figure 13 Workspace manager showing several workspaces
You can switch from one workspace to another by double-clicking
on the workspace that you want to switch to in the Workspace
manager.

You also can close windows or entire workspaces from the
contextual menu (Figure 14).

contextual menu
TIP: Hover the mouse over a saved workspace to preview its
content.

Lesson 3 Synchronization Tool
The Synchronization tool allows the asset teams to work in a
collaborative environment where data can be transferred to and
from a shared Techlog project.
Each team member must create a personal project on their local
space and from this personal project, they can link to the shared
one. After the projects are linked, team members can share their
data with the community through a send and retrieve mechanism.
Figure 15 How the Synchronization tool works
Project Partial Loading Feature
It is recommended that you disable the Project partial loading
functionality when using the Synchronization tool, because the
Synchronization tool displays only the wells loaded in the
Project browser. Using the Project partial loading feature might
lead to a mismatch between the Reference repository and the
current project.

Procedure 1 Disabling the Project Partial
Loading Feature
This procedure shows you how to disable the Project partial
loading feature in Techlog.
1. Go to the Project tab in the Project browser Properties
window.
2. Select Options.
3. Go to the Parameters tab.
4. Clear the Partial project loading check box.
5. Click OK to validate.
Procedure 2 Linking Techlog to the Reference
Repository
NOTE: This procedure assumes that the Reference repository
is created already.
1. Create a new Techlog project on your private disk space.
2. In the Techlog main window, select Utility >
Synchronization > Synchronization tool.
3. Click Link and browse to the location of Reference
repository. The Current project is now linked to the
Reference repository.

Procedure 3 Retrieving Items from the
Reference Repository
This procedure shows you how to retrieve items from the
Reference repository to include them in your current project.
1. From the Reference repository pane, select the items to
retrieve.
2. Click to move the items to the Current project pane.
3. Click Close to exit the Synchronization tool. The items are
displayed in the Project browser.
NOTE: The Send and Retrieve actions are performed at the
data set level only.

Procedure 4 Sending Items from the Current
Project to the Reference
Repository
In this procedure, you send items from a local project to the
reference repository.
1. After you worked on your data, reopen the Synchronization
tool.
2. From the Current project pane, select the items that you
modified.
3. Click to send the items you modified to the Reference
repository pane.
Data Locking
You can lock data to prevent other users from overwriting the data
that you currently are working with. When data is locked, other
users still can retrieve them and modified them locally (in each
user project), but they cannot send their own changes to the
Reference repository.
You can lock data and view the locked items from either the
Current project or Reference repository pane. However, the
items are locked in the Reference repository pane only.
Therefore, items that exist only in the Current project cannot be
locked. In case of an error, a warning window opens listing all the
objects that were not locked in the Reference repository.

Procedure 5 Locking Data
If you want to send a Techlog object to the Reference
repository, you must lock it first.
1. From both Synchronization tool panes, select the items to
lock.
2. Click Lock.
3. Click Close to validate. From the Project browser, you can
see a padlock on each locked item.
NOTE: From the Project browser, you can see only the
data that you locked. Go to the Synchronization tool
to see the data locked by other users.
If another user forgets to unlock the data, a data
administrator can unlock them.
If all the items in a specific group are locked, a padlock on
the group name is displayed.
If you have items inside a group with at least two different
lock statuses, the icon is displayed in the parent Lock
status column.
NOTE: When several users use the same Reference
repository to exchange modified data, some
conflicts might appear between your Current project
and the Reference repository. Several tools exist to
resolve potential conflicts. A discussion of these tools
is beyond the scope of this training. More information
is available in the Techlog User Guide.

Lesson 4 Techlog Project Creation
In this lesson, you will learn how to create a new project in
Techlog.
Procedure 1 Creating a New Techlog Project
The first time you open Techlog, most of the menus and dock
windows are disabled (they appear in gray). This is because no
project is open. You will need to create a new project first.
The Project template option allows companies to define clear
formats for any feature in Techlog that must be applied for a
dedicated addressee. This option typically is offered to service
companies that deliver standard output on a per customer basis.
The Project template option copies the whole project (including
data) defined as a template into the newly created project. All of
the settings applied in the project template then are available for
the new data that will be loaded into the new project.
1. In the Techlog main window, select Project > New to
open the New project wizard.
2. In the New project wizard, enter this information:
• Project name: Avoid using a slash () in the project name.
• (optional) Country: Entering a country will help you to filter
your projects later.
• (optional) Description: Enter information about the project.
3. Click Next to go to the Folder, status and type page.
The project is added to your Project folder automatically. If
you wish to store it in another directory, click the ellipses (...)
button to navigate to and select another location.
4. (optional) Choose a Project template from the list, or
browse for it by clicking the ellipses (...) button.
5. Set these options for the project template:
• Project status: In progress or temporary.
• Project opening default mode: In Techlog 2012, only single-
user is available (options are read/write or read only).

• Project plug-in: For best performance, choose SQLite.
• Unit system (optional): This option is available only if a
company folder exists.
6. Click Next.
A message appears asking you to confirm the creation of the
new project folder.
7. Select the modules that you wish to use. You can change this
selection after you create the project.
8. Click Finish.

Exercise 1 Creating the My First Techlog
Project
In this exercise, you create your first Techlog project named My
First Techlog Project.
1. In the Techlog main window, select Project > New to
open the New project wizard.
2. Enter the Project name, Country, and Description.

3. Click Next.
The Folder, status and type window opens. In this window,
you can modify the storage path for your project. For this
exercise, use these values:
• Project status: In progress
• Project opening default mode: single user [read/write]
• Project plug-in: SQlite
• Unit system: Undefined (for the moment, no company folder
is installed).
4. Click Next.
A confirmation dialog box opens asking you to confirm the
project folder creation.
5. Click Create.
Techlog creates the new project folder.

6. Select the modules that will be checked out when you open
the project.
7. Click Next.
The project has now been created. Techlog displays a
summary of your project characteristics.

8. Click Finish to open your newly created project.
Notice that all of the icons are now active. You can start to
upload data into your project.
Techlog Project Folder Structure and Settings
When a project is created, Techlog creates a structure of folders
as shown in Figure 16. Each of these folders contains all of the
objects (such as plots, layouts, and processing parameters) saved
at the Project level.
Figure 16 Project folder structure
The project settings are stored in Settings.xml file located in the
Settings directory. This file contains this information:
• Name of the project
• Name of the person who created the project
• Creation date
• Modification log
• Opening mode
• Licenses used in the project.

Procedure 2 Opening an Existing Project
You can open an existing project from the Project menu where
the most recent Techlog projects are listed.
1. In the Techlog main window, select Project > Recent
projects.
A list of the ten most recently saved projects appears.
2. Select the project you want to open.
A confirmation window opens asking if you want to replace
the current project or open the project in a new Techlog
session.

Procedure 3 Opening an Older Project
This procedure shows you how to open a project if it is not one of
the ten most recently saved projects.
1. In the Techlog main window, select Project > Open to open
the Project selection window.
2. Select the project you want to open, then click Open.

NOTES

Schlumberger Internal Use Only Data Import and Export
Module 2 Data Import and Export
Techlog can integrate many types of data, including log data,
point data, seismic, deviation files, and image files. Techlog also
supports a variety of the most common formats, including LAS,
GeologASCII, DLIS/LIS, ASCII file with the wizard, core images,
TechCSV, and the Techlog format (XML).
In addition, you can export data or any object created in Techlog
(such as plots and layouts) from Techlog to various format such
as LAS, DLIS, GeologASCII, ASCII file, TechCSV, and the
Techlog format (XML).
Learning Objectives
After completing this module, you will know how to:
• import data files, such as DLIS, LAS, and TXT formats
• import spreadsheet files
• import image files, such as PNG and TIFF
• import XML Techlog files
• export data from Techlog
• use the Well Identification Solver.
Lesson 1 Data Import
You can import data in four ways:
• Drag the files to be imported into Techlog (LAS, DLIS,
Techlog XML, CSV files).
• Select Project > Import from the main Techlog window.
• Select Home > Import .
• Press Ctrl + Shift + J,I.
Regardless of the method you choose, the action opens the
import buffer (Figure 17) in the Project browser window.

Data Import and Export Schlumberger Internal Use Only
The import buffer holds all of the data that you choose to import in
a temporary space. You can quality check the properties of each
variable before you import it into the project.
Figure 17 Project browser (left) and the import buffer (right)

Procedure 1 Importing Data
This procedure is applicable for most of the files you will load into
Techlog.
1. Select Home > Import to open the import buffer.
2. Click Open and browse for the files to be imported.
3. If the data cannot be parsed automatically by Techlog, the
ASCII Import wizard opens.
4. In the Properties window of the wizard (on the right side),
define these parameters:
• The data set type you wish to import: continuous, point
data, or interval. (If you are importing zonation data sets,
make sure the Dataset type property is set to interval .)
• The location of header information in the ASCII file (Import
from line, Variable name line, and Unit line).
• Delimiter settings.
5. Click Preview.
6. In the Preview window, define these parameters:
• Reference column (mandatory)
• If applicable, the Well name and Dataset name columns.
You can remove the unnecessary columns by clicking
Remove column(s).
NOTE: It is not necessary to define the Variable and Array
columns. Techlog identifies them automatically.
7. Click Load to the import buffer.
8. Click to import the data into the Project browser.
9. After data has been imported, click Delete to clear the
content of the import buffer.
10. Click Close to close the import buffer.

Lesson 2 DLIS File Import
There are two ways to import *.dlis data: File(s) import or
Selective DLIS import.
File(s) import (Figure 18) loads the header and the data, applies
the family assignment rules, and calculates statistics when
loading to the buffer.
Figure 18 File(s) import dialog box
Selective DLIS import (Figure 19) loads the header into the
buffer and applies the family assignment rules (quick load). When
you transfer files to the Project browser, it loads the data and
calculates statistics.
Figure 19 Selective DLIS import dialog box

This type of import is useful when working with large files or when
you wish to view the content of the file. Imported data is displayed
in the import buffer where you can verify that all variables are
present.
After data is imported into the buffer, choose the data sets to be
imported into the project and click the green arrow to move
them into the Project browser (Figure 20). You can observe the
progress of the import in a Techlog window.
Figure 20 Data import into the Project browser

Exercise 1 Importing DLIS Log Files
In this exercise, you load .dlis data into your project.
1. Select Home > Import .
2. In the import buffer, select Files(s) import from the drop-
down menu.
3. Click Open .
4. Choose the files listed in the Techlog_201201 DLIS
directory and click Open. You now have five files in the
import buffer:
• Well1.dlis
• Well2.dlis
• Well3.dlis
• Well4.dlis
• Well9.dlis.
5. The files are added as well names. Expand each well and
look at the data sets.
6. There is a problem with the name of the DATAFULL file in
Well 2. Remove the underscore (_) in the file name
a. Right-click on the data set.
b. Select Rename, or press F2.
7. Choose all the data sets named DATAFULL for all five wells.
TIP: Use the conditional selection to select only the
DATAFULL data sets.
8. Click the green arrow to import the data into the Project
browser.
9. Verify that your data was imported correctly by expanding the
wells and the data sets.
10. Click on a variable and view it in the Properties dock
window. The properties for each variable display.
TIP: The shortcut for viewing the Properties window is F4.

11. In the Project browser, note that variables display in black,
gray, or red.
• Black indicates a variable has a unit and has been assigned
to a family.
• Gray indicates the variable is missing a family or a unit.
• Red indicates the variable has no unit and no family
assigned to it.
This display helps you to harmonize and quality check the
data. (These topics are discussed later in the training.)
12. After you quality check the data, click Delete to clear the
content of the import buffer.
TIP: If you click the X (in the upper right corner of the
window) to close the import buffer, both the import
buffer and the Project browser window will close. To
reopen the Project browser and import buffer, right-
click Dock windows and select Project browser.

Lesson 3 LAS File Import
When importing *.las files, select File(s) import (Figure 21) from
the drop-down menu in the import buffer. All other steps in the
import process are identical to the procedure for importing *.dlis
data.
Figure 21 LAS file import dialog box

Exercise 1 Importing LAS Files
In this exercise, you load the Hole Azimuth and Deviation surveys
into Techlog. These surveys are provided as .las files.
2. Select File(s) import from the drop-down menu.
3. Click Open .
4. Choose these files listed under Techlog_201202 LAS and
click Open.
• Well1.las
• Well2.las
• Well3.las
• Well4.las
• Well9.las
5. Expand each well and view the data sets.
6. Choose the data set SURVEY for all five wells and click to
import the data into the Project browser.
This figure shows the Project browser after adding the
SURVEY files.

7. Verify that your data was imported correctly by expanding the
wells and the data sets. You can see that the SURVEY data
set has been added to each well.
This figure shows the Project browser after the SURVEY
data is imported.
8. Click on a variable and view it in the Properties dock
window. The properties for each variable display.
Notice that some variables display in black, gray, or red.
• Black indicates a variable has a unit and has been assigned
to a family.
• Gray indicates the variable is missing a family or a unit.
• Red indicates the variable has no unit and no family
assigned to it.
9. Clear the content of the import buffer.
10. Close the import buffer.

Lesson 4 Text File Import
Text files are imported as *.las files using the File(s) import
command. Before *.txt files are added to the import buffer, they
display in the Data import wizard window (Figure 22). In this
window, you can verify that your data will be correctly imported.
The Data import wizard allows you to configure many
parameters.
• Dataset type (continuous data, point data, intervals)
• Specific lines from which to import
• Line for unit, if it exists
• Delimiter of the original file.
Figure 22 Data import wizard for zones import

Exercise 1 Importing Stratigraphy Data from
a TXT File
In this exercise, you import the stratigraphy data for Well1, Well2,
Well3, Well4, and Well9. Before you start the exercise, you can
open the .txt file to review the data you are about to import, as
shown in the figure.
3. From the folder Techlog_201203 TXT, select the ZONES.txt
file to import. The Import Wizard window opens.
4. In the Property area, change the Dataset Type to Interval.
Notice that there are no units in this file.
5. Add the unit (FT) to the Reference variable.

6. Click Preview.
Your Data import wizard window should match this figure.

8. Make a quality check of the data added to the import buffer.
TIP: You can select multiple files to add to the import buffer.
Exercise 2 Importing the TOPS1 File
In the next exercises, you import three files. Because you can add
multiple files in the Techlog import buffer, you will do the final
import to the Project browser at the end of Exercise 3.
3. From the folder Techlog_2012Exercises01 Import
Exercise01 Import various test configurations, select to
import the file TOPS1.txt. The Data import wizard window
opens.

4. In the Data import wizard window, define these parameters:
• Well name column
• Dataset name column
• Reference unit
• Dataset type (Interval).
Two settings are configured automatically:
• Variable name line is set to 1.
• Data import is done from line 2.
NOTE: These settings should be verified for any future files.

In this exercise, you import the file named TOPS2.
Exercise01 Import various test configurations, select to
import the file TOPS2.txt. The Data import wizard window
opens.
4. In the Property area, set the Zonation mode to zonation.
You now are able to select Top or Bottom in the table, as
shown in the figure in Step 5.
NOTE: The property Dataset type was automatically set to
interval.
5. Define the Top and Bottom columns and verify that they have
the correct units.

In this exercise, there is no need to define the reference
curve. The Top variable will be used as a reference.
6. Define the Well name column.
7. Define the Dataset name column in the Property area
(TOPS2). If no column is defined as Dataset name, you have
the option of entering a name.
8. Verify that Import from line is set to 3.
Red error messages display in the output dock window
during the import process.

10. Review the original file and make corrections as needed.
Notice that a dot is missing in line 26 of the original file.
Instead of displaying a depth of 10983.4, the depth is
displayed as 109834.
TIP: It is possible to edit the file that is currently loaded with
the wizard. Any modification performed (and saved) in
the original file will be immediately propagated in the
wizard after clicking Preview.
11. After saving corrections to the TOPS2.txt file, repeat Step 1
through Step 5 to import it.
In this exercise, you import the file named TOPS3.
Exercise01 Import various test configurations, import the
file TOPS3.txt. The Data import wizard window opens.

4. In the Property pane, define Delimiter > Others as a ( ' )
separator and click Preview.
5. Set Keep consecutive separators to no and click Preview.
6. Add a unit (ft) to the Reference column.
7. Define the Dataset name as TOPS3.
8. Set the Dataset type as interval.
9. Import the data into the Project browser.
10. Clear the contents of the import buffer.
Lesson 5 CSV Spreadsheet Import
Core data is imported as point data in *.csv format using the
File(s) import command. Display the Data import wizard to
verify or change property settings.
NOTE: Excel files (.xls and .xlsx) are binary files and cannot be
imported using the ASCII import wizard. If you must
import Excel data in *.xls (MS Office 2003) or *.xlsx (MS
Office 2007 and 2010) formats, save the files in the *.csv
format, then import the .csv files into Techlog.
Exercise 1 Importing a CSV Spreadsheet
In this exercise, you upload core analyses in .csv format.
1. Open the folder Techlog_201204 CSV and import the Well1
file. The Data import wizard opens.
2. Verify that these property settings are correct or make
changes accordingly:
• Set the Dataset type to Point Data.
• Set the Variable name line to 1.
• Set the Units line to 2.
• Set the Import from line to 3.

• Add the unit ft to the reference if it was not previously
added.
• Change the Comma delimiter to yes.
After your point data is added to the import buffer, you should
see a display similar to the figure. The name of your point
data set should be MICP.
3. Repeat Step 1 and Step 2 to import Well2, Well3, Well4, and
Well9 MICP data.
Exercise 2 Importing Formation Pressure Data
In this exercise, you upload formation pressure data provided as
an Excel file.
1. Open the Excel file formation pressure.xlsx from the
Techlog_2012Exercises01 Import Exercise02 Tables and
spreadsheets folder and save it with the same name in a
comma delimited file .csv format.
2. Upload the .csv file into Techlog.
3. Set the Comma delimiter to yes.
4. Change the first column to be the reference.
5. Import the data into the import buffer only.
Notice that the curves were imported as array (vector)
data . This is done because in the original file, at least one
depth repeats itself.

7. In the import buffer, click on the word Datasets.
8. In the Properties window, under the ASCII import parameter,
select Array creation policy.
9. Choose the add an epsilon to the reference value option. This
option remains selected for any type of data.
This configuration is not optimal for other types of data, such
as Capillary Pressure curves. Choosing the ask for each case
option could be useful for future import sessions.
10. Upload the .csv file into Techlog again.
Notice that this time the RFT variables are displayed with the
Point data icon .
11. Configure the Well name and Dataset name by right-clicking
and using the contextual menu.

Exercise 3 Importing a Thin Section Analysis
Table
In this exercise, you upload a different type of data: a thin section
description provided as a .csv file.
Exercise02 Table and spreadsheets, import the file Thin
section analysis.csv.
4. In the Data import wizard, set the variable name line
property of the original file to 3.
5. Click Preview. Notice that this file has no units.
6. Set the unit line property to 0.
7. Click Preview. Notice that, in this instance, the application
begins importing the file only from line 10.

8. Set the import from line property to 4 and click Preview.
9. To visualize additional lines in the lower table, increase the
number of available lines and click Preview.
10. Define the curve that will be the reference curve of the data
set.
11. Add units to the curves.
12. Enter a Dataset name.
13. Remove the Well name from column 1 and add the correct
well name.
Lesson 6 Image File Import
Image files can be imported using the Images import with
wizard command (Figure 23) in the import buffer.
Figure 23 Images import with wizard command
In the Image import wizard window, you set parameters in the
Dataset information and Image information areas of the wizard to
determine how Techlog should read the file. Upon import, you
can either copy the actual file and place it in the project, or copy a
link to the location of the image.

The Image import wizard window (Figure 24) allows you to
choose and preview image files to import.
Figure 24 Image import wizard for image files
Procedure 1 Importing Images
This procedure shows you how to load core data images into
Techlog.
2. Select Images import with wizard from the drop-down
menu.
3. Click Open and navigate to your image folder.
4. Choose all the images you wish to load and click Open. The
Image import wizard opens.
NOTE: Techlog allows you to import *.png, *.tif, *.jpg, *.bmp,
and *.gif image formats.

5. Enter a name using the correct naming convention.
You can enter the name or choose a predefined pattern. The
name of images file must comply with the naming convention
for images. For example, if your image is named
Well1_CoreImages_1567.png, the naming convention is
%WellName%_%DatasetName%_%DepthTop%
If the name of the file is more complex (for example, if the
core image file is CD10789 with 10789 as the top depth of
the core), you must type CD%DepthTop% with CD before the
% to make sure Techlog recognizes the depth automatically.
6. Copy images into the project by selecting the Copy all images
into the project check box.
If you do not select this option, a link will be created between
the variable and the actual image during the import process.
TIP: If there are a lot of images to copy, the performance of
Techlog could be affected; select the Convert all images
into 8 colours bits check box.
7. In the Dataset information zone:
a. choose a proper unit
b. enter a Dataset name
c. enter a variable name.
8. Click Preview to view the correctly displayed depth
reference.
9. Click Load to the import buffer. The data set is now added
to the import buffer.
11. Click Delete to clear the contents of the import buffer.

Exercise 1 Importing Core Images
Core images cannot be imported by dragging them into Techlog.
The data need to be imported using Image import wizard to be
sure Techlog puts the images at the correct depth. In this
exercise, you load some .png and .tiff core images into your
Techlog project.
2. Select Images import with wizard from the drop-down
menu.
3. Navigate to the folder Techlog_201205 Core images PNG/
Well9/Daylight and choose all files.
4. Click Open. The Image import wizard window opens.
5. Select the Copy all images into the project check box.
NOTE: You are importing the file, not creating a link to the
file.
6. In the Images information area, the Name model field
extracts information from the file name.
7. Scroll to the end of the file name list and locate Top Depth –
Bottom Depth, as indicated in the Name model field:
%DepthTop%-%DepthBottom%.

8. In the Dataset information area, choose ft from the drop-
down list in the Depth unit field.
9. Click Load to import buffer.
10. Load the second image data set by selecting Image import
with wizard from the drop-down menu in the Import
browser.
11. Navigate to the image folder Techlog_201206 Core Images
TIF/Well9/UV and choose all files.
12. Click Open. The Image import wizard window opens.
13. Configure parameters to import *.tiff files.
14. Select the Copy all images into the project check box.
15. Verify the name model to be %DepthTop%-%DepthBottom%.
16. Because this core image data set is using Core Depth as a
reference, in the Dataset information area, enter the Depth
name field CDEPTH and choose FT from the drop-down list
in the Depth unit field.

The table in the lower left corner shows you how the data is
stored (a data set with a link to the image at each depth). The
scale in the right lower corner lets you preview the images.
17. Review the depth table and note the empty intervals.
18. In the lower right corner of the window where a view of the
image is available, modify the zoom factor.
Each time you click Preview to apply a modification, the
scale is updated.
TIP: The Maximum interval option is ignored when the top
and bottom are available. If only tops are available,
Techlog runs a check on the difference between them,
then determines the maximum interval.
If the difference between tops is longer than the
maximum interval, the core length will be equal to the
maximum interval. This prevents the core image from
being stretched between the two tops.
The data is now added to the import buffer. You can see the
DaylLight and UV data sets under Well9. Notice the different
references: MD for the DayLight data set and CDEPTH for
the UV data set.
20. Choose Well9 and click to import the data into the Project
browser.

Lesson 7 XML File Import
XML files are data files that have been previously processed and
exported in Techlog. This format contains all the additional
information that a variable can carry, including an associated
palette and well color.
There are two ways of importing xml files into Techlog. Method 1
uses the import commands on the menu; Method 2 uses a drag-
and-drop function.
Procedure 1 Importing XML Files from the
Import Buffer
In this procedure, you import an .xml file created in Techlog using
the import buffer.
3. Click Open to choose the .xml file you wish to import. The
data you import are automatically loaded into the import
buffer.
4. Choose the data and click to import it into the Project
browser.

Procedure 2 Importing XML Files with a Drag-
and-drop Method
In this procedure, you import xml files using a drag-and-drop
method.
1. Drag your .xml file into the display area.
The files are parsed automatically in the import buffer,
because .xml is the Techlog native format.
Techlog XML data file is the preferred format when
exchanging data between Techlog users, because it
preserves all Techlog-specific settings (Families, History,
Well Color).
2. Choose the data and click to import the data into the
Project browser.

Exercise 1 Loading the LQC data
In this exercise, you import an .xml file created in Techlog
containing Log Quality Control (LQC) data.
1. Drag the XML files from the Techlog_201207 XML.xml
folder into the display area.
The LQC data set for the five wells is now in the import
buffer.

Notice that wells have a color and variables have a history as
shown on the History tab of the Properties window.
2. Select all the wells by pressing Ctrl + A within the import
buffer.

Lesson 8 Time Data
In this lesson, you will learn how Techlog handles time data. In
the previous exercises, all the references were Measured Depth.
Sometimes you might have to upload data with a different
reference such as time data.
Techlog manages data with 16 significant figures (double
precision data). This allows it to support date-time data. A variable
is considered date-time data when its family is Date Time.
You can create a data set with a reference in date-time by
following a simple workflow within the Project browser or the
Data editor. You also can import and save date-time data in a
Techlog project. All data processing tools (such as resampling,
combining or resizing data sets, and time shift) work with date-
time data.
In Techlog, a Date-time reference is stored as a number of milli-
seconds since January 1st 1900. For example, December 21st
1983, 21:26:11 is stored in the database as 2649878771116.07
ms.
You can load these date-time formats into Techlog:
• yyyy-MM-dd hh:mm:ss.zzz
• yyyy-MM-dd hh:mm:ss
• yyyy/MM/dd-hh:mm:ss
• yyyy/MM/ddThh:mm:ss
• dd/MM/yyyy-hh:mm:ss
• dd/MM/yyyy hh:mm:ss
• hh:mm:ss dd-MMM-yy
• hh:mm:ss/dd-MMM-yyyy
• hh:mm:ss.zzz
• hh:mm:ss

To upload other formats, go to the Import buffer Properties
window where you can add a specific date-time format that is not
handled by Techlog by default.
You will need to combine these expressions to import specific
date-time files.
Table 1: Expressions to Create Date-time Formats
Expression Output
h The hour without a leading zero (0 to 23 or 1 to 12 if
AM/PM display)
hh The hour with a leading zero (00 to 23 or 01 to 12 if
AM/PM display)
H The hour without a leading zero (0 to 23, even with
AM/PM display)
HH The hour with a leading zero (00 to 23, even with AM/
PM display)
m The minute without a leading zero (0 to 59)
mm The minute with a leading zero (00 to 59)
s The second without a leading zero (0 to 59)
ss The second with a leading zero (00 to 59)
z The millisecond without a leading zero (0 to 999)
zzz The millisecond with a leading zero (000 to 999)
AP or A Use AM/PM display. AP will be replaced by either AM
or PM
ap or a Use am/pm display. ap will be replaced by either am
or pm

Exercise 1 Uploading Time Data
In this exercise, you upload a file containing time data. The
reference for this file is in milliseconds, a format that is recognized
by Techlog automatically.
1. Drag the file 1_Well9_DateTime.las XML from the
Techlog_2012Exercises01 Import Exercise05 Time data
folder into the display area.

The DateTime data set is added to the Project browser.
Notice the reference, which is TIME with Date Time as the
family and ms as the unit.
Exercise 2 Uploading Time Data with Time
Reference
In this exercise, you upload a second file containing time data as a
reference. If you drag this file into Techlog, the file will be
uploaded as any ASCII file. However, in the Project browser, you
can see that the time reference has no family. It will not load
correctly.
Furthermore, in the Project browser, the reference appears to
have no family and no unit. This indicates that the time format has
not been recognized by Techlog.

1. Open the file Techlog_2012Exercises01 Import
Exercise05 Time data2_Well9_TimeData.asc in a text
editor.
The first column is your time data. The format is not in the list
of recognized formats. You will need to enter this specific
format in the Import buffer Properties window.
3. In the Import buffer Properties window, enter the time date
format using the convention presented in Table 1 and shown
in this figure.
4. Drag the file 2_Well9_TimeData.asc into the import buffer.
5. In the Data import wizard, change the well name to Well9.
The import buffer displays the contents of the LAS file.
