Cutting Settling in Deviated Wells Cause Stuck Pipe

For deviated wells, cuttings tend to accumulate at the low side of the wellbore and form a cutting bed. When there is a lot of cutting bed, it will fall down and pack the string when circulation is ceased. Moreover, while pulling out of a hole, BHA will move some cutting beds and finally, the cutting bed will pack BHA and drill string (stuck pipe).

Note: A well which has an inclination of more than 35 degrees is classified as a deviated well.
