International Classification:

E21B 33/035
E21B 33/038
E21B 33/043

Abstract:

A subsea wellhead assembly having an arrangement of primary well barriers provided in equipment that is located within the well and/or the wellhead housing is provided. The subsea wellhead assembly may include a tubing hanger positioned in or below a wellhead housing coupled to a subsea well, a tree cap fluidly coupled to the tubing hanger and disposed atop the wellhead housing, and a pair of master production valves configured to be selectively actuated from an open position to a closed position to shut in the subsea well, each of the pair of master production valves located within or below the wellhead housing.

International Classification:

E21B 33/035
E21B 43/013
E21B 17/01

Abstract:

A subsea production system and method for installing the same are provided. The subsea production system includes a high pressure subsea wellhead, a tubing hanger landed proximate the wellhead, a production tree disposed above the wellhead downstream of the tubing hanger, a riser, a subsea flowline system coupled between the production tree and the riser, at least one barrier located downstream of the tubing hanger, and a secondary barrier valve disposed within the tubing hanger or in line with and upstream of the tubing hanger. The at least one barrier provides a pressure barrier that controls pressure of fluid flowing from components of the subsea production system located upstream of the barrier to components of the subsea production system located downstream of the barrier, and the secondary barrier valve is remotely actuable between a closed position and an open position.

Abstract:

In accordance with the present disclosure, a full top-to-bottom subsea system and method used to drill, complete, produce, and perform interventions on HPHT subsea wells is provided. The disclosed systems and methods involve the use of a controlled multiple barrier system, such as a high integrity pipeline protection system (HIPPS), incorporated into the subsea system to divide the system into two sections. The sections on either side of the barrier may be rated for different pressures, temperatures, and/or flow rates. For example, the first section (upstream of the barrier) is rated for operating at pressures/temperatures/flow rates up to a first (higher) threshold. The second section (downstream of the barrier) is rated for operating at pressures/temperatures/flow rates up to a second (lower) threshold. The disclosed subsea production system methodology, which uses barriers to divide the system components between two pressure ratings, may allow for enhanced development of HPHT reservoirs.
