METHODS AND APPARATUSES FOR DETERMINING TRUE VERTICAL DEPTH (TVD) WITHIN A WELL

摘要

A method of determining true vertical depth within a well penetrating a ground surface, the method including: positioning a pressure sensor at a downhole position within the well at the base of a fluid column extended from a ground surface to the pressure sensor; measuring, with the pressure sensor, a pressure exerted by the fluid column; and determining the true vertical depth (TVD) of the downhole position using the pressure measured by the pressure sensor. An apparatus for determining true vertical depth within a well, the apparatus including: a tubing string; a housing connected to the tubing string, the housing defining a chamber and having a port to the tubing string; a pressure sensor mounted to the housing and in fluid communication with the chamber.
