In general, differential sticking is a situation that may happen during any stage of drilling the well and cause the drill string or casing to stuck (no upward or downward movement). It actually happens when the hydrostatic pressure, ph (which acts on the outside wall of the Pipe) is more than the pore … See more Simple precautions tips to decrease the possibility of Differential pipe sticking if drilling through high permeable intervals are as following: 1. Decrease drilling mud fluid loss. ( Check API Fluid Loss, HPHT Fluid Loss). 2. … See more After you understand the freeing procedures, we recommend that you have a look at the freeing chart. 1.

Torque And Dragincrease. 2. Unable to reciprocate or in … See more Differential sticking is a problem that occurs when drilling a well with a greater well bore pressure than formation pressure, as is usually the case. The drill pipe is pressed against the wellbore wall so that part of its circumference will see only reservoir pressure, while the rest will continue to be pushed by wellbore pressure. As a result, the pipe becomes stuck to the wall, and can require milli…
