How does inadequate hole cleaning contribute to the occurrence of differential sticking, and what specific drilling parameters should be adjusted?

Inadequate hole cleaning significantly contributes to differential sticking by allowing a thick filter cake of drill solids to build up on the wellbore wall, especially in permeable formations. Differential sticking occurs when a portion of the drill string becomes embedded in this filter cake due to a pressure differential between the wellbore and the formation. The pressure in the wellbore is intentionally maintained higher than the formation pressure to prevent influx, but this pressure difference forces the drill solids against the drill string, creating a strong adhesive force. Inadequate hole cleaning means that drill cuttings are not effectively....
