Abstract
A subsea pumping system using a subsea module is installed on the sea bed, preferably away from production wells and intended to pump hydrocarbons having a high associated gas fraction produced by subsea production wells to the surface. The system achieves an advantage by the design of a pumping module (PM) which is linked to pumping equipment already present in a production well and which includes: an inlet pipe (), separator equipment (), a first pump () and a second pump (). Another advantage of the subsea pumping system for the production of hydrocarbons with a high gas fraction is that, when oil is pumped from the production well (P), the well pump () increases the energy of the fluid in the form of pressure and transmits this increase in energy in the form of an increase in suction pressure in the second pump () of the subsea module (PM).
