WebApr 15, 2024 · Differential sticking occurs when the hydrostatic pressure of mud is greater than the formation pressure, pushing the drill string into a filter cake of permeable formation. When differential sticking occurs, it’s virtually impossible to move the drill string in an upward or downward direction, requiring operators to reduce the hydrostatic ... WebAfter drilling 100 m, it is attempted to keep the mud weight above the median line for the rest of the section. However, at the bottom, the mud weight of Fig. 10.6 drops below the median line for the following reasons: • to minimize the risk of lost circulation and • to minimize the risk for differential sticking. breastfeeding teas to avoid
