A STABLE ORGANIC-BASED FLUID LOSS ADDITIVE CONTAINING AN ORGANOPHILIC CLAY-BASED SUSPENDING AGENT FOR USE IN A WELL

摘要

The present invention provides a well treatment composition comprising: a water- soluble, organic liquid, wherein the organic liquid comprises the continuous phase of the well treatment composition, and wherein the organic liquid comprises a polyglycol or a derivative of polyglycol; a fluid loss additive, wherein the fluid loss additive is insoluble in the organic liquid, and wherein the fluid loss additive comprises a high molecular weight, water-swellable polymer; and a suspending agent, wherein the suspending agent comprises an organophilic clay, wherein the well treatment composition has an activity of at least 15%. The present invention also provides a method of cementing in a subterranean formation comprising: introducing a cement composition into the subterranean formation, the cement composition comprising: (i) cement; (ii) water; and (iii) the well treatment composition; and allowing the cement composition to set after introduction into the subterranean formation.
