The usual problem is differential sticking due to a higher pressure in the bore hole compared to a lower formation pressure. This causes the drilling string (Drill Pipe, Drill Collars, BHA) to be forced against the wall cake. The wall cake or filter cake is deposited across low permeable zones causing the filter cake to build up, By reducing the hole pressure, by circulation chemicals or simply diesel oil to the stuck point,which reduces the hole hydrostatic pressure is often the easiest way to get unstuck.
