Introduction to drilling

  1. 1. WELCOME
  2. 2. INTRODUCTION TO DRILLING
  3. 3. DRILLING RIG
  4. 4. DRILLING RIG SITE LAYOUT
  5. 5. INTRODUCTION DRILLING: It is defined as art & science of making a hole in an object. OIL & GAS WELL DRILLING: It is an art & science of drilling a hole in the earth crust down to a desired depth in search / extraction of natural gas or oil(petroleum).
  6. 6. When science is used for the benefit of mankind, it may take any other shape. Two such forms are 1. ENGINEERING 2. TECHNOLOGY
  7. 7. ENGINEERING Engineering is the science of machines. It is primarily connected with analysis of mechanisms involved, design, construction, operation and maintenance of the machines. So Drilling Engineering is the science of machines which are involved in drilling a petroleum well or simply a well.
  8. 8. TECHNOLOGY It is basically the science of Methods . When methods are standardized we call them Techniques. When techniques are used for commercial purpose, we call them Technologies. So Drilling Technology is the science of standard methods or techniques which are used / employed for drilling an oil or gas well(commercial purpose).
  9. 9. DRILLING SYSTEMS Oil well drilling engineering may easily be divided into following drilling systems. A system is a sum or group of various machines, equipments & instruments etc. Rig System Power System Mud Handling / Circulatory System Hoisting System Rotary System Well Control System Instrumentation System Auxillary System
  10. 10. RIG SYSTEM Generic word used in two ways:-  A plant / unit for drilling a hole in the ground. OR A machinery system which is used to make a hole in the ground. OR A system which is composed (made) of various mechanical & electrical sub systems / equipments for drilling a hole into the ground.
  11. 11.  A tower type structure erected to make a hole / bore in the ground. Parts: Bottom box Under structure Rig / Derrick floor Mast
  12. 12. POWER SYSTEM Diesel Engines, Alternators, Bus Bar, PCRS (SCR unit), Cables, Motors, Switches, Regulators (for speed control).
  13. 13. MUD HANDLING SYSTEM Super Charger, Mud Pumps, Pipes (HP line, stand pipe & H manifold), Rotary Hose, Flow Nipple, Flow Line, Shale Shaker, De Sander, De Silter , Mud Cleaner, Mud Tanks and Agitators etc.
  14. 14. HOISTING SYSTEM Draw Works, crown block, travelling block and drilling line or casing line etc.
  15. 15. ROTARY SYSTEM Swivel, Rotary Table, Kelly, Kelly bushing, Drill Stem ( drill pipe, drill collar, stabilizers, different substitute), Bit etc.
  16. 16. WELL CONTROL SYSTEM Well Head, D / Spool, Spacer Spool, K / Line, C / Line, Ram Bop, A / Bop, Gas Buster, Accumulator Unit, Hydraulic Lines.
  17. 17. INSTRUMENTATION SYSTEM Measuring Instruments Pressure Gauges, SPM Gauge, R.P.M Gauge, Torque Gauge, Weight Indicator, MVT (Mud Volume Totalizer), Ton Mile Indicator, Recorder, Cables, etc.
  18. 18. AUXILLARY SYSTEM AC Lighting system, Air Supply / Pneumatic System ( Compressor, lines, Receiver), Water Supply System, Tool Tackles, etc.
  19. 19. DRILLING TECHNOLOGY It is a science of standard methods or techniques which are used / employed for drilling an oil or gas well.
  20. 20. DRILLING TECHNOLOGIES Mud Casing Rig Hydraulics Bit Drilling Cementing Special (Directional, Complications, Fishing etc.) Well Control
  21. 21. DRILLING OPERATIONS Operations involved in drilling a well are : Rig Building Spudding-In of the Well Drilling (1st, 2nd, 3rd Phase) Logging Casing Lowering
  22. 22. Cementing Well Head Fitting & Testing BOP Fitting & Testing Fishing & Complication Operation Hermetical Testing
