Title: (EN) WELLBORE SERVICING COMPOSITIONS COMPRISING A FLUID LOSS AGENT AND METHODS OF MAKING AND USING SAME
Abstract:
(EN) Disclosed is a method of servicing a wellbore comprising: preparing a composition comprising a calcium aluminate cement, water, and a fluid loss additive, wherein the calcium aluminate cement comprises aluminum oxide in an amount of greater than 60 wt. % based on a total weight of the calcium aluminate cement and wherein the fluid loss additive comprises an acid gelling polymer (such as comprising a mixture of guar or cellulose, and crosslinking agent; or comprises a synthetic polymer comprising copolymers of acrylamide and 2-acrylamido-2-methylpropane sulfonic acid (AMPS); copolymers of acrylamide and acrylic acid; copolymers of acrylamide and trimethylaminoethylmethacrylate chloride; copolymers of acrylamide and trimethylaminoethylmethacrylate sulfate; copolymers of acrylamide and trimethyaminoacrylate chloride; copolymers of acrylamide and trimethylaminoacrylate sulfate; copolymers of AMPS and dimethyl amino ethyl methacrylate (DMAEMA); N-vinylpyrrolidone/AMPS copolymers; terpolymers of acrylamide, 2-acrylamido-2-methylpropane sulfonic acid and acrylic acid; terpolymers of acrylamide, acrylic acid and trimethylaminoethylamethacrylate chloride; terpolymers of acrylamide, acrylic acid and trimethylaminoethylmethacrylate sulfate; terpolymers of acrylamide, acrylic acid and trimethylaminoethylacrylate chloride; terpolymers of acrylamide, acrylic acid and trimethylaminoethylacrylate sulfate; or combinations thereof); placing the composition in the wellbore; and allowing the composition to set, wherein the composition has a fluid loss of from 10 cc/10 min to 600 cc/30 min at a temperature of from 50��F (10��C) to 500��F (260��C)...
