Well test: Evaluates the properties of the reservoir and the potential production rate. 2. Cementing: Secures the casing in the wellbore and prevents fluid migration between formations. 3. DST String: Used in Drill Stem Testing to obtain pressure data and fluid samples from the reservoir. 4. 3-Phase separator: Separates the produced fluid into oil, gas, and water phases. 5. Shale shaker: Removes large solids (cuttings) from the drilling fluid. 6. Swivel: Allows the drill string to rotate while holding the weight of the drill pipe. 7. Mud Box: Collects and directs the drilling mud returning from the wellbore to the mud tanks. 8. Catwalk: Provides a space to temporarily store and handle drill pipe and other equipment. 9. Kelly pipe: Transfers rotational force from the rotary table to the drill string. 10. Casing pipe: Prevents the collapse of the wellbore and isolates different underground layers. 11. GR & SP Logs: Gamma Ray and Spontaneous Potential logs identify lithology and evaluate formation properties. 12. Darcy Equation: Describes the flow of fluid through a porous medium. 13. Seismic Survey: Uses reflected seismic waves to map subsurface geological structures. 14. Retarders: Slow down the setting time of cement in high-temperature wells. 15. Starches & CMC: Used as additives to control fluid loss and viscosity in drilling mud. Q4 Sure, here are the solutions for the given cases: 1. Avoid gas production from oil reservoirs: Use gas lift or gas injection techniques او تخلي الضغط اقل من ضغط الفقاعة. 2. Measure the mud density: Use a mud balance. 3. To classify hydrocarbon reservoirs according to their fluid properties and phase behavior: Perform PVT (Pressure, Volume, Temperature) analysis. 4. To classify oils (light, medium, and heavy): Use API gravity measurements. 5. Cement evaluation: Conduct cement bond logs. 6. Cool the drill string, especially drill bit while drilling: Use drilling mud for cooling. 7. Increase the cement slurry density to prevent kicks: Add barite or other weighting agents. 8. Increase the ability of drilling fluid to lift cuttings: Use viscosifiers like bentonite. 9. Avoid corrosion in casing pipes and downhole equipment by drilling mud: Add corrosion inhibitors to the mud. 10. To measure wettability: Perform contact angle measurements or Amott test. 11. Avoid loss circulation while drilling: Use lost circulation materials (LCMs). 12. Reach the oil reservoirs in inaccessible places and under salt domes: Employ directional drilling techniques. 13. To provide a circulation system for drilling fluids and ensure stability under the rig in offshore rigs: Use a riser system. 14. Pump the cement inside the casing by drilling fluid but not mixing (cement and fluid) together: Use cementing plugs. 15. Rotate the drill string while drilling: Use a rotary table or top drive system.
