Drilling Engineering
5 self-contained study topics — notes, diagrams, formulas, and worked examples for exams and GATE.
Topics
- Drilling FluidsDrilling fluid design controls pressure, cuttings transport, and borehole stability; in B.Tech numericals, mud weight and ECD are the first checks before drilling ahead.
- Drill String DesignDrill string design balances axial load, torque, and fatigue life so required WOB reaches the bit without exceeding pipe limits.
- Well ControlWell control ensures influx is contained and circulated out safely using shut-in data, kill mud weight, and a controlled pressure schedule.
- Casing DesignCasing design checks burst, collapse, and tension loads with API ratings and selected safety factors for each string depth.
- Directional DrillingDirectional drilling uses measured surveys to control inclination and azimuth so the wellbore hits the planned reservoir target window.
