摘要

A system and method utilizing a painted joint simulator to reduce the time required to conduct a dummy run in order to space out subsea test equipment within a blow-out preventer. In certain embodiments, a heavy weight fluid is injected into a chamber of the joint in order to assist in its downhole descent speed. In other embodiment, a high pressure fluid is injected into a second chamber of the joint in order to force the heavy weight fluid out of the joint in order to assists in the assent back to the surface.
