Abstract

The present invention provides a system and method for use of desulphated injection water from offshore platforms for utilization in inhibition squeeze operations. The system is capable of increasing the treatment capacity by joining the pumping system from the stimulation vessel with the water injection system from the offshore platform. In the initial treatment step, according to the method of this invention, the fluid containing the inhibitor is pumped exclusively by the vessel, followed by an aqueous overflush, where the injection water is mixed with part of the inhibitor cushion pumped by the stimulation vessel.
