HOUSTON -- Argus Subsea is using the Offshore Technology Conference to introduce a new subsea tree and wellhead designed for jackup drilling rigs. The AZ-153 is the first purpose-built system that can drill and complete wells up to 15,000 psi working pressure without special riser systems or temporary abandonments, says Argus.

The well is drilled with conventional casing program to total depth, gravel packed and the tubing hanger is set and tested in the wellhead prior to breaking back all tie back strings. After the tie-backs are retrieved, the subsea tree is run landed, tested and left with the appropriate barriers in place before the tieback is made to the host facility.

“The AZ-15J can save a minimum of 15 days rig time as compared to the current industry standard drilling and completions time,” says Carl Aubrey, general manager, Argus.
