An early production system includes an Emergency Disconnect Package ("EDP"), a production riser coupled between the EDP and a sea surface processing facility, a gas export tubing coupled between the EDP and the sea surface processing facility, and a flow base. The flow base is detachably connectable to the EDP. The flow base also includes an Independent Production Control System ("IPCS") for controlling at least one production valve.

Embodiments of the present invention relate to an underwater gas/liquid-liquid modular separation system which enables the disposal of produced water in undersea environment. The underwater gas/liquid-liquid modular system separation consists of a gravitational separator and a water polishing system consisting of deoiling membranes capable of withdrawing the residual oil contained in water. Furthermore, the underwater gas/liquid-liquid modular separation system also features a demulsifier injection which promotes the breakdown of the water-oil emulsion. Embodiments further relate to an underwater gas/liquid-liquid separation method and to the use of deoiling membranes in gas/liquid-underwater liquid separation systems.

The devised modular of 'Subsea Level Gas Separator of Oil Well Effluent (SLGOE) precludes giant gas entrainment entering the rig. The effluent, past the BOP, is diverted by gravity through a 'diversion' tube, into the bottom of 1-3 'gas separator' tanks, creating fountain-like flow. The downstream, syphoned from an 'oil passage tank', joins the partitioned collection system past the 'diversion' tube. The large top outlets of 'all' tanks let off 'instantly' rising gases. In another embodiment of two 'gas separator' tanks, oil flows from the top of the first. Its bottom outlet directs it into the top of the second. From it, oil is siphoned to the collection system. The large top outlets of both tanks instantly let off gases. In either device, the gas 'instantly' separates from the effluent tossed into aerial milieu of the tanks, a simplest model conceivable, the laws of nature taken advantage of.

It is described a subsea fluid processing system adapted to receive a wellstream flow (1A, 101A) comprising a pressure control device (2,112) adapted to regulate the pressure of the wellstream flow (1A, 101A), a gas-liquid separator unit (4,105) adapted to receive the wellstream flow (1A, 101A) downstream of the pressure control device (2,112) and provide a liquid stream (4A, 105A) and a gas stream (4B, 105B), a first membrane separator (5,106) adapted to receive the gas stream (4B, 105B) and provide a retentate stream (5B, 106A) and a permeate stream (5A, 106B), a compressor (6,110) adapted to receive the permeate stream (5A, 106B) and provide a compressed permeate stream (6A, 110A), a discharge cooler (7, 111) adapted to receive the compressed permeate stream (6A, 110A) and provide a cooled permeate stream (7A, 111A) for injection into a subsurface reservoir, whereby the cooled permeate stream (7A, 111A) has higher density than the compressed permeate stream (6A, 110A).
摘要:
A subsea fluid processing system is provided containing a liquid reservoir, an inlet tank, a pump, an outlet system, and a fluid re-circulation loop. The liquid reservoir circulates a primer liquid stream to the inlet tank via the fluid re-circulation loop. The inlet tank further receives a first production fluid stream and mixes it with the primer liquid stream to produce thereby a second production fluid stream having a reduced gas volume fraction (GVF) relative to the first production fluid stream. The pump receives the second production fluid stream from the inlet tank and increases its pressure. Further, the outlet system containing the liquid reservoir receives the second production fluid stream from the pump and separates at least a portion of the primer liquid stream from a principal production stream. The primer liquid includes at least one exogenous liquid not derived from the first production fluid stream.

A system (2) for offshore hydrocarbon processing comprises a host (6) at surface level, a subsea processing plant (4), and an umbilical (8) connecting the host and the subsea processing plant. The subsea processing plant is adapted to receive a multi-phase hydrocarbon stream (10) from a wellhead and to output at least a hydrocarbon gas-phase stream (14) satisfying a rich gas pipeline transportation specification to a pipeline. The umbilical provides a desiccant (12) for drying the hydrocarbon gas, as well as power and control (12), from the host to the subsea processing plant.
