Patent ID: 8511386

Claim:
A subsea pumping system for the production of hydrocarbons with a high gas fraction, said system comprising a stationary production unit and a pumping module installed on the sea bed alongside an oil production well (P), comprising: a first transport pipe (T 1 ) which links the stationary production unit with the annulus of the production well (P) to deliver drive fluid to a well pump ( 13 ) installed at the bottom of a production well (P) draining a reservoir (R); a second transport pipe (T 2 ) connecting the outlet of the well pump ( 13 ) to an oil inlet pipe ( 2 ) of the pumping module; and a third transport pipe (T 3 ) connecting the outlet pipe ( 9 ) of the pumping module (PM) to the stationary production unit, wherein the pumping module contains separator equipment ( 3 ) connected to the oil inlet pipe ( 2 ), whereby oil originating from the oil production well is separated into a high gas fraction stream and a high liquid fraction stream, flowing separately.
