Proposed Project Work Flow for Reservoir Characterizations
1. Geologic Analyses: (KIC will work directly with your geologic and engineering teams)
Interpret existing (available) cores and DST’s; review published reports, articles, Master & Ph.D. Thesis;
evaluate and interpret well logs. Incorporate existing (available) DST data; generate well log sequence
stratigraphic cross sections; develop reservoir stratigraphic fence diagram(s)/3D models; and perform
Look Back Evaluations on selected wells. These analyses will assist in identifying PUD’s (1P, 2P, & 3P
locations) and identifying & high grading infill locations with potential greater producibility. The
deliverables for geologic analyses will consist of at a minimum: geologic maps, facies maps, sequence
stratigraphic cross sections, 3-D fence diagrams, and reservoir type logs. Examples of the Geologic
Analyses are presented on slides 4, 5, 6, 7, 8 & 9.

Unconventional DST’s:
Numerous DST’s have been performed in older wells. These
DST’s were performed in conventional wells with the
expectations of good hydrocarbon recoveries and pressures.
The DST’s that indicated marginal recoveries and pressures
were either completed as dry holes or were marginal
uneconomic wells. These DST’s are excellent examples of
DST’s in unconventional tight oil reservoirs.
Core Resource Libraries:
Available for lithofacies analysis for any formation.
Lithofacies analysis is critical in the identification
of transgressive/regressive systems tracts in well
log sequence stratigraphy and the correlation of
well log patterns between wells.

Geologic Analysis – Well Log and Sequence Strat Interpretations, Parkman Sandstone
Location Map - Powder River Basin
Lithologic well Log correlation based on the Formation Top of the Parkman Sandstone. As
a result, there is a great possibility to actually drill through 2 different reservoirs that
may have different reservoir parameters (oil saturation, pressures, water saturations,
etc.) and may yield a well with underperforming results and expectations.
Lithologic Parkman top.
Time Chronological well log sequence strat correlation is based on the time chronological
top of the identified prospective reservoir. This correlation allows for the proper
placement of the horizontal well bore to stay in the target zone in the identified
prospective reservoir. As a result, expectations for a successfully drilled well are
achieved and the potential for a successful completion and well performance expectations
are also achieved.

2. Geologic Database Analyses:
Incorporate any previous work acquired by Your Company for detail evaluation and geologic
interpretations. The previous work may include petrophysical analysis, service companies data, such as
BHT, GOR, detail core studies, purchased databases etc. An example of the Geologic Database Analyses is
presented on slide 11.
Proposed Project Work Flow for the Reservoir
Characterizations
10
An Example: Geologic Data & Database Analysis
The TGS borehole temperature model database can present
multiple geologic attributes and assist in the identification of
sweet spots and geothermal reservoir compartments. As a
result, infill locations can be high graded, volatile oil & gas
reservoirs identified, PUD’s identified, timing and migration of
hydrocarbons, all of which can result in Greater Producibility.

3. Source Rock and Rock Mechanic Evaluations:
Existing/available inorganic and organic geochemical and rock mechanic’s data would be interpreted &
incorporated as well as conductivity & proppant data. Additional geochemical (inorganic and organic) and
rock mechanical data may need to be collected but not until the existing data has been assessed.
Deliverables will include: frackability maps (potential of a rock to frack) which includes lithofacies
evaluation, oil migration maps (depending on the data). We provide evaluation and interpretation for
these type of data which are than incorporated in the Reservoir model. An example of the existing Rock
Mechanical Data is presented on slide 13.

Core Resource Libraries:
Available cores will be interpreted, some of which
may have inorganic & organic data. This data will be
incorporated with the existing log interpretation.
The amount of quartz and calcite is important in
determining the frackability of the rock (potential
of a rock to frack). Hence, the depths 1902, 1917
and 1934 are going to be much better candidates
for fracking than the other depths. The
combination of the quartz/calcite and clays will
provide evidence to determine the best fracking
candidates.

An example of the Geophysical Evaluation is presented on slide 15.
14
Existing geologic structural interpretations will be incorporated
into the Geophysical Evaluations and Interpretations for structure,
fracture & derivative analyses, sequence strat analysis, and
reservoir modeling for the given formation(s). Integration of
existing of 2D & 3D seismic is required. We can work together with
your geophysicists, or provide contractors and integrate seismic
interpretation into the Reservoir Characterization Model.

Deliverables for the Reservoir Characterization
1. Geologic Analyses: geologic maps, facies maps, sequence stratigraphic cross sections, 3-D
fence diagrams, and reservoir type logs.
These will allow for understanding the reservoir lithofacies compartments and their characteristics
and identifying sweet spots (directly related to drilling and completion approaches and reservoir
economics).
2. Geologic Database Analyses: BHT, GOR, WOR and resistivity maps.
These will allow for identification of geothermal reservoir compartments; volatile oil & gas reservoirs;
and potential hydrocarbon timing and migration pathways.
3. Source Rock and Rock Mechanic Evaluations: frackability maps (potential of a rock to frack)
which includes lithofacies evaluation.
This is directly related to drilling and especially completion approaches to target sweet spots and
rocks with better frackability, oil migration, maturity, frack barriers, i.e., bentonites.
4. Geophysical Evaluation & Interpretation: fracture maps.
This will allow for better targeting and understanding structural component (traps) related to the
reservoir lithofacies.
5. Reservoir Engineering Analyses Include Completion & Drilling Evaluations: producibility maps.
This will allow for complete integration and targeting the most productive zones.

The proposed work flow presented in these slides for the Reservoir Characterization of any formation can
be accomplished with the existing geologic, geophysical, petrophysical information, and databases.
The proposed Reservoir Characterization study will be accomplished by a driven, focused oriented Geologic
Team consisting of Cal Reppe, Keith McDonald, and Vanja M. Stevanovic, geologists, in addition with Doreena
Patrick (geochemist) and Shirley Somerville (reservoir engineer). The Geologic Team’s knowledge and
expertise will be utilized to achieve a timely and efficient evaluation of the multiple aspects of any
integrated project. In addition, this team is committed to work with the Geophysical and Engineering Teams
to deliver a successful reservoir characterization model for you.
The purpose of a Reservoir Characterization is to incorporate existing data from geology, geochemistry
(inorganic & organic), petrophysical, and geophysical evaluations with the Reservoir Engineering data. As a
result, the multi-disciplinary team will be able to develop a reservoir model/strategy for each
producing horizon that will optimize the IP’s, EUR’s, ROR, ROI, NPV, high grade infill locations with
greater producibility, and identify PUD’s. Therefore, enhance the overall economics of the reservoirs
and the asset. All integrated data can be applied immediately for an overall better performance
In the current economic climate in the Oil & Gas Industry, a Reservoir Characterization will propagate the
true potential market value of any asset for potential interested buyer’s and financial investors. The
proposed Reservoir Characterization will improve, enhance, and optimize your economics for any reservoirs
target.

  • 3. Proposed Project Work Flow for Reservoir Characterizations 1. Geologic Analyses: (KIC will work directly with your geologic and engineering teams) Interpret existing (available) cores and DST’s; review published reports, articles, Master & Ph.D. Thesis; evaluate and interpret well logs. Incorporate existing (available) DST data; generate well log sequence stratigraphic cross sections; develop reservoir stratigraphic fence diagram(s)/3D models; and perform Look Back Evaluations on selected wells. These analyses will assist in identifying PUD’s (1P, 2P, & 3P locations) and identifying & high grading infill locations with potential greater producibility. The deliverables for geologic analyses will consist of at a minimum: geologic maps, facies maps, sequence stratigraphic cross sections, 3-D fence diagrams, and reservoir type logs. Examples of the Geologic Analyses are presented on slides 4, 5, 6, 7, 8 & 9. 3
  • 4. Unconventional DST’s: Numerous DST’s have been performed in older wells. These DST’s were performed in conventional wells with the expectations of good hydrocarbon recoveries and pressures. The DST’s that indicated marginal recoveries and pressures were either completed as dry holes or were marginal uneconomic wells. These DST’s are excellent examples of DST’s in unconventional tight oil reservoirs. Core Resource Libraries: Available for lithofacies analysis for any formation. Lithofacies analysis is critical in the identification of transgressive/regressive systems tracts in well log sequence stratigraphy and the correlation of well log patterns between wells.

  • 5. Geologic Analysis – Well Log and Sequence Strat Interpretations, Parkman Sandstone Location Map - Powder River Basin Lithologic well Log correlation based on the Formation Top of the Parkman Sandstone. As a result, there is a great possibility to actually drill through 2 different reservoirs that may have different reservoir parameters (oil saturation, pressures, water saturations, etc.) and may yield a well with underperforming results and expectations. Lithologic Parkman top. Time Chronological well log sequence strat correlation is based on the time chronological top of the identified prospective reservoir. This correlation allows for the proper placement of the horizontal well bore to stay in the target zone in the identified prospective reservoir. As a result, expectations for a successfully drilled well are achieved and the potential for a successful completion and well performance expectations are also achieved.

This data will be incorporated with the existing log interpretation. The amount of quartz and calcite is important in determining the frackability of the rock (potential of a rock to frack). Hence, the depths 1902, 1917 and 1934 are going to be much better candidates for fracking than the other depths. The combination of the quartz/calcite and clays will provide evidence to determine the best fracking candidates. 13

  • 19. The proposed work flow presented in these slides for the Reservoir Characterization of any formation can be accomplished with the existing geologic, geophysical, petrophysical information, and databases. The proposed Reservoir Characterization study will be accomplished by a driven, focused oriented Geologic Team consisting of Cal Reppe, Keith McDonald, and Vanja M. Stevanovic, geologists, in addition with Doreena Patrick (geochemist) and Shirley Somerville (reservoir engineer). The Geologic Team’s knowledge and expertise will be utilized to achieve a timely and efficient evaluation of the multiple aspects of any integrated project. In addition, this team is committed to work with the Geophysical and Engineering Teams to deliver a successful reservoir characterization model for you. The purpose of a Reservoir Characterization is to incorporate existing data from geology, geochemistry (inorganic & organic), petrophysical, and geophysical evaluations with the Reservoir Engineering data. As a result, the multi-disciplinary team will be able to develop a reservoir model/strategy for each producing horizon that will optimize the IP’s, EUR’s, ROR, ROI, NPV, high grade infill locations with greater producibility, and identify PUD’s. Therefore, enhance the overall economics of the reservoirs and the asset. All integrated data can be applied immediately for an overall better performance In the current economic climate in the Oil & Gas Industry, a Reservoir Characterization will propagate the true potential market value of any asset for potential interested buyer’s and financial investors. The proposed Reservoir Characterization will improve, enhance, and optimize your economics for any reservoirs target. 19 The Reservoir Characterization
