Mud circulation monitoring provides real-time verification of hydraulic balance, hole cleaning, and primary well control during drilling. It sits in the drilling execution phase, interfacing tightly ...

Manual pressure management in a closed-loop mud circulating system enhances safety and efficiency of drilling and completion operations. Manual pressure management in a closed-loop mud circulating ...

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

But one British group believes it is feasible -- and should also be considerably cheaper -- to site the whole thing on the seafloor. A seabed drilling rig that can carry out the same activities as a ...
