PETROLEUM DIRECTORY: New undersea tree from Schlumberger

Schlumberger Oilfield Services has added a new high-performance tree for subsea wells in water depths of up to 10,000 feet.

The new SenTREE HP has a bore of 6 3/8 inches and a working pressure rating of 15,000 pounds per square inch. It can be used for horizontal subsea Christmas tree technology, and also can be brought in as a conventional tree.

The new technology will allow testing and completion of exploration, appraisal and development wells in difficult underwater environments.

Schlumberger is upgrading its Commander telemetry in-riser controls to match the SenTREE HP system. The new control systems will provide a 15-second response time to shut in the well and disconnect the landing string in any water depth.
