see Free Point Constant. Used in stuck pipe depth calculations.

n: an area or point above the point at which a tubular, such as drill pipe, is stuck in the wellbore.

n: the depth at which pipe is struck, or more specifically the depth immediately above the point at which pipe is stuck.

a technique for estimating the highest free point in a string of stuck pipe. It is based on a differential stretch calculation with amount of pull and the free point constant (FPC).

a calculation used in the stuck pipe calculation to correct for pipe wall thickness and diameter.
