..., in this situation, high formation fracture pressures required high surface injection pressures to push the fluid & cuttings into the formation. When the injection pressure was combined with the frictional losses through the drill string, anticipated surface pressures were over 10k psi when circulating...

... The non-linear stiction, friction and energy losses that occur during dynamic impacts between the drill string and the borehole wall are physically handled more realistically by multi-body dynamics than by the typical linear quasi-static approach employed by conventional torque and drag models...

... . Maximum casing wear was reported to be 60% wall thickness (WT) loss at approximately 2,300ft MD. Abstract Casing wear caused by rotating drill strings can lead to reduced well life, failed or burst casing strings, and expensive non-productive time (NPT) for remedial actions. In Alaska's Alpine...

.... In fact, the potential for wellbore collapse is highest during cleanout and hole-enlargement operations because of the need to pull the drill string out and then trip back in with an underreamer tool, which leaves the open hole exposed. Sidetracked wells that start by drilling a pilot hole require...
