{{#category_index:K|keyseat}} Where a borehole changes direction so that the drilling pipe rubs the side of the borehole, the effect is to wear a groove in the borehole wall. The drill pipe may fit in this groove but the groove may be smaller than the couplings between units of drill pipe, making it difficult to pull the drill pipe.
