SUBSEA DUMMY RUN ELIMINATION ASSEMBLY AND RELATED METHOD UTILIZING A LOGGING ASSEMBLY

摘要

A system and method to eliminate the need for a dummy run comprises a logging assembly to detect the position of one or more blow-out preventer (“BOP”) rams and a hang off location. During a logging operation, the logging assembly logs the positions of the BOP rams and wear bushing. The logged positions are then used to determine the correct placement of the subsea test tree (“SSTT”) in relation to its hanger. Thus, the need to perform a dummy run is eliminated because correct placement of the SSTT can be determined during routine logging operations.
