Schlumberger - Drilling and Measurement Segment - Internship Presentation

I learnt about all the Drilling and Measurement equipment and procedures. During the internship period, I had to survey few technical modules which were specific to Drilling and Measurment segment, which included
• an introduction to Drilling & Measurment segment and its core services
• interpretation of Direction & Inclination terminologies
• learning of Telemetry procedures and working of Measurement While Drilling tools
• understanding of Surface System structure.

  1. 1. Presented to Mr. Zeeshan Saeed Prepared by D&M Operation Manager Zorays Khalid Ghulam Ishaq Khan Institute of Engineering Sciences and Technology Drilling & Measurement Examining the operations at DnM 1
  2. 2. Outline • Introduction to D&M • Rig components • Rotary Table System with Kelly • Down hole survey: Why? How? • D&I Terminologies • Directional hole drilling: Tool face • Telemetry and MWD Tools • Surface System: SPT and RTS • Way Forward 2
  3. 3. Introduction to Drilling and Measurement segment Core services provided by DnM: • Measurements While Drilling (MWD) • Logging While Drilling (LWD) • Directional Drilling (DD) • Drilling Optimization (PD) 3
  4. 4. Rig Components There are four systems or components: 1. Power System 2. Hoisting System 3. Rotary System 4. Circulating System http://www.tariemultimedia.com 4
  5. 5. Rotary System with Kelly http://www.tariemultimedia.com 5
  6. 6. Downhole Survey Work drill string Reduce flow rate Lock drill string Increase flow rate Detect Additional MWD signal steps Examine data 6
  7. 7. Terminologies? • Surface Location • Kickoff Point • Well Profile • Target Area • Horizontal Displacement • Vertical Section • Inclination • Azimuth • TVD • Magnetic Interference • BHA 7
  8. 8. Tool face • Orientation of mud motor in the wellbore • GTF Orientation relative to high side of well bore (0° to ± 180°) • MTF Orientation relative to north (0° to 360°) • Tool face Correction Mud Motor Scribe Line 8
  9. 9. MWD Telemetry Process • Telemetry is the process of transmitting data from one place to another • The process includes: 1. Down hole measurements T Al 2. Data conversion M ur te 3. Signal generation u bi rn 4. Signal propagation d n at e or 5. Surface sensor acquisition 6. Signal demodulation M o d ul at or m ot or R ot or 9
  10. 10. Surface Systems • The purpose is to collect and process data about drilling parameters and geological information about formation. • Surface system is composed of five main parts: 1. Sensors (Signal Pressure Transducer, Rotary Torque Sensor) 2. Sensor peripherals 3. Computers 4. Logging units 5. Peripheral components 10
  11. 11. Way Forward • Sonic logging while drilling • The expanding role of mud logging • A hybrid rotary steerable system • Shale gas: a global resource 11
