Abstract
A process is provided for reducing the pressure for injecting a solution of water-soluble polymer from a given injection pump into various oil wells in a given field as a function of the fracturation pressure for each well. Between the injection pump and each well, a respective main volumetric pump is placed. The fracturation pressure of each well is detected with a respective manometer, and the flow rate of each volumetric pump is controlled, using a brake, as a function of detected fracturation pressure of the respective well.
