At-a-Glance: Safety compliance in deepwater drilling is achieved by rigorous barrier management, disciplined well-control engineering, and a closed-loop assurance system (plan–execute–verify–improve) ...

Coiled tubing enables rigless, live-well access to mechanically, chemically, or hydraulically intervene in wells to restore/optimize inflow, clean and repair completion hardware, place treatments ...

Drilling operations cause changes in wellbore temperatures that can significantly impact effective fracture gradients. For example, circulation on bottom usually produces bottomhole temperatures that ...

Compared to conventional vertical wells, complications from formation pore pressure, borehole stability, hole cleaning, drillstring torque and drag, and other parameters create serious challenges for ...
