terms:differential_pressure_sticking
A condition in which the drill stem becomes stuck against the wall of the wellbore because part of the drill stem (usually the drill collars) has become embedded in the mud cake. Necessary conditions for differential-pressure sticking (or wall sticking) are a permeable permeable formation, a pressure differential across a nearly impermeable mud cake, and drill stem.
