METHOD FOR ENHANCING PRODUCTIVITY OF HYDROCARBON FORMATIONS USING FLUID CONTAINING ORGANOMETALLIC CROSSLINKING AGENT AND SCALE INHIBITOR

摘要

Scales are prevented or inhibited from forming in a well or in a formation penetrated by a well by pumping into the well a fluid comprising a hydratable polymer, a crosslinking agent, such as an organometallic crosslinking agent containing a polyvalent metal and a scale inhibitor selected from the group consisting of polyvinyl sulfonates, a polyacrylamidomethylpropane sulfonic acid, carboxymethyl inulin and sulfonated polyacrylates and mixtures thereof.
