Manual pressure management in a closed-loop mud circulating system enhances safety and efficiency of drilling and completion operations. This is the second of a four-part series of articles on the ...

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

It was an early adopter of super-spec rigs (AC drive, minimum 1,500 horsepower drawworks, minimum of 750,000 pounds hookload rating, 7,500 psi mud circulating system, and multiple-well pad capability) ...

The term‘managed pressure drilling´or MPD is relatively new, and used primarily to distinguish the method from underbalanced drilling. Underbalanced drilling invites influx or the flow of hydrocarbons ...
