Abstract

A system, in certain embodiments, includes a tubing hanger running tool (THRT) configured to position a tubing hanger within a wellhead. The THRT includes an integrated pressure equalization system including a tube having a first end in fluid communication with an annulus of the wellhead, and a second end in fluid communication with a control line. The integrated pressure equalization system also includes a piston disposed within the tube. The piston is configured to move within the tube to balance a pressure differential between a first fluid within the annulus and a second fluid within the control line.
