Completion subsea test tree
This field-proven modular system consists of
The SenTREE 7 test tree provides large-bore (7.375-in [187-mm]) well access, dual-barrier well control, and a reliable means to disconnect the completion landing string in the event of an emergency.
Two independently controlled barriers—a ball valve and a flapper valve—govern wellbore fluid flow at the subsea BOP. These valves are fail closed to secure the wellbore if hydraulic control pressure is lost.
If required, the ball valve assembly can be used to cut a variety of media, including slickline, wireline, and coiled tubing. The ball valve can cut 2.0-in-OD coiled tubing (0.156-in wall thickness, 95,000-psi yield) in an emergency. An optional module can be added for increased cutting capability, if required. The retainer valve provides environmental protection by holding hydrocarbons in the landing string after disconnect.
Operating system options for the SenTREE 7 test tree support operations performed from anchored or dynamically positioned vessels in water depths ranging from shallow to ultradeepwater.
Multiple hydraulic and electrical ports allow customization of the SenTREE 7 test tree for
