Gear-driven drawworks have gained greater acceptance in the drilling industry. They achieve improved safety, optimal performance and control, considerable weight re duction, and increased reliability ...

Rig area networks, remotely operated hoisting systems, more powerful drilling fluid hydraulics, and easy-to-install blowout preventer (BOP) assemblies have improved operations for several ...

Rotary drilling is used in almost all oil and gas wells drilled globally. In this method of drilling, a length of steel pipe- with a drill bit on the end is rotated to cut a hole called the well bore.

Quality control (QC) in drilling ensures that safety-critical barriers, equipment, materials, and procedures consistently meet defined acceptance criteria so the well remains within pore-pressure and ...
