Why do we use a subsea test tree assembly (SSTTA) during well test clean-up operations? To create a dual barrier in-riser subsea safety system required to control the hazards associated with bringing live hydrocarbons to the surface and providing the capability to disconnect/reconnect the well. The subsea test tree is positioned inside the rig’s blowout preventer (BOP) and spaced out so that, if needed, the BOP shear rams can be activated across the SSTTA shear sub. | Expro

Subsea Operations Method Online Course Preview The typical operation of subsea production system can be summarized as follows: Oil, gas and water flow from wellbore to subsea tree, thence to jumper, manifold and flowline, before finally reaching a riser that pipes it to surface for processing. Pressurized reservoir fluid samples collected in an open hole wellbore may be analyzed at surface to characterize the physical properties of the fluids.
