AB1000-SUBSEA COST DATABASE

Subsea production systems are typical wells located on the sea floor, shallow or deep water. Generally termed as Floating production system, where the petroleum is extracted at the seabed and the same can be tied back to an already existing production platform or an onshore facility. The oil well is drilled by a movable rig and the extracted oil or natural gas is transported by pipeline under the sea and then to rise to a processing facility.

Subsea production systems are generally arranged as shown in Figure X-X. Some subsea production systems are used to extend existing platforms. For example, the geometry and depth of a reservoir may be such that a small section cannot be reached easily from the platform using conventional directional drilling techniques or horizontal wells. Based on the location of the tree installation, a subsea system can be categorized as a dry tree production system or a wet tree production system. Water depth can also impact subsea field development. For the shallower water depths, limitations on subsea development can result from the height of the subsea structures.

Christmas trees and other structures cannot be installed in water depths of less than 30 m (100 ft.). For subsea development in water depths less than 30 m (100 ft.), jacket platforms consisting of dry trees can be used.
