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.

System and method for use of desulphated injection water from offshore platforms for utilization in inhibition squeezes

A system and method for inhibiting or removing scaling in wells equipped with intelligent completion (IC), including sealing failures, includes a mixture of viscous gel and solid material in different granulometries is used and spheres soluble in water and in oil. The system and method aim to maintain production of wells equipped with intelligent completion and aim to reduce costs in relation to operations commonly performed with rigs.

Method of remote divergence for wells equipped with intelligent completion

A joint application process of two treatments, scale removal and inhibitor squeeze injection, is described herein. Through the simultaneous positioning inside the reservoir, it can be applied in scale removal operations for carbonate formations, such as the pre-salt case. Accordingly, there is a way to improve the efficiency of reservoir management, through an innovation in the scaling management process.
