Abstract
An enhanced recovery method that optimizes the stages of pumping, transport and surface treatment of the production effluent, during which a sweep fluid having at least one polymer so as to displace hydrocarbons towards a production well is injected into a reservoir, the resulting production effluent having hydrocarbons is collected through the production well, and a degradation agent for a polymer within the sweep fluid is injected into the effluent.
