Operating system for increasing the recovery of fluids from a deposit, simplifying production and processing installations, and facilitating operations with enhanced safety

摘要

A system involving at least one well equipped with an elevated or sub- sea production head, and at least one pipeline collecting the effluent from the production head leading to an effluent phase separation unit. The system comprises, in addition, a tube in the form of a U-tube connected to the unit and dipping into the sea to a predetermined depth; the exit in the sea of this U-tube can open into a balancing column that protects the air-sea interface from fluctuations due to the state of the sea. The invention also makes it possible to regulate the input pressure into the installations at a value which is preferably close to atmospheric pressure.
