n: to find the top position of freeze-in zone where the drilling pipe is checked with free point detector or by bachreaming the pipe

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

free point indicator tool.

n: pipe above which is over free point on freeze in drill column.

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).

Free Point analysis followed by downhole unscrewing of a pipe coupling above the stuck point.

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

n: A wireline tool used to determine the free point on a stuck string. The free-point indicator operates by detecting stretch in the tubular when tension is applied at surface. If stretch is not detected, the string must be stuck above the tool;if stretch i

a tool with strain gauges that is run on wireline and moved along the stuck pipe with successive pipe pulls until the stuck point is located.

n: the tool that ascertain the point of the top of fish and free point of drilling point.
