Drilling Supervisor Interview Questions and Answers

There are several types of horizontal wells, including simple, multilateral, extended reach, and complex wells.

• Simple horizontal wells are the most basic type, drilled horizontally from a vertical wellbore.

• Multilateral horizontal wells have multiple lateral branches extending from the main wellbore.

• Extended reach horizontal wells are drilled to reach distant reservoirs from a single location.

• Complex horizontal wells involve various wellbore configurations and drilling techniq...read more

Selecting the right bit for a formation involves considering the formation type, drilling parameters, and bit design.

• Consider the type of formation being drilled (e.g. soft, hard, abrasive)

• Evaluate the drilling parameters such as weight on bit, rotary speed, and mud properties

• Choose a bit design that is suitable for the specific formation characteristics

To pressure test a BOP, follow proper procedures, use appropriate equipment, monitor pressure levels, and record results.

• Ensure all connections are secure before pressurizing the BOP

• Gradually increase pressure to the specified level and hold for the required time

• Monitor pressure gauges and watch for any leaks or abnormalities

• Record the pressure test results for documentation and analysis

Rigging out a bit involves removing the drill bit from the rig floor.

• Ensure the rig floor is clear of any obstructions before rigging out the bit.

• Use proper lifting equipment to safely remove the bit from the rig floor.

• Inspect the bit for any damage or wear before storing it properly.

• Document the rig out process in the drilling report for future reference.
