schlumberger - drilling and measurement segment - internship presentation
DESCRIPTION
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.TRANSCRIPT

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 Forward2 3. Introduction to Drilling and Measurement segmentCore services provided by DnM: Measurements While Drilling (MWD) Logging While Drilling (LWD) Directional Drilling (DD) Drilling Optimization (PD)3 4.

MWD Telemetry Process Telemetry is the process of transmitting datafrom one place to another The process includes:1. Down hole measurementsTAl2. Data conversionMurte3. Signal generationubirn4. Signal propagationdnateor5. Surface sensor acquisition6. Signal demodulationModulatormotorRotor9 10. Surface Systems The purpose is to collect and process data aboutdrilling parameters and geological informationabout formation. Surface system is composed of five main parts:1. Sensors (Signal Pressure Transducer, Rotary Torque Sensor)2. Sensor peripherals3. Computers4. Logging units5. Peripheral components10 11. Way Forward Sonic logging while drilling The expanding role of mud logging A hybrid rotary steerable system Shale gas: a global resource11 12.
