Identify the recommended overpull by multiplying 2208.5 by pipe weight/ft. Pull the calculated overpull(F) (Not to exceed the yield strength of the pipe) causing the free portion of the pipe to stretch to a new position (X 2)(in). Use the following equation to calculate the free point from the rig floor: L sp = 735,294(X 2 − X 1)W dp ÷ F

In addition to controlling the downhole (occurring in the drilled hole) pressure and the flow of oil and gas, blowout preventers are intended to prevent tubing (e.g. drill pipe and well casing), tools, and drilling fluid from being blown out of the wellbore (also known as bore hole, the hole leading to the reservoir) when a blowout threatens.
