摘要： Methods of reducing the fluid loss from a wellbore servicing fluid include combining a terpolymer with the wellbore servicing fluid to reduce the fluid loss from the fluid, followed by displacing the fluid into a wellbore. In an embodiment, the following monomers are used to make the terpolymer: from about 75 wt.% to about 95 wt.% of 2-acrylamido-2-methylpropanesulfonic acid or an alkali salt thereof; from about 3 wt.% to about 15 wt.% of acrylamide; and from about 3 wt.% to about 15 wt.% of N-vinyl-2-pyrrolidone, all weight percentages being based on a total weight of the monomers. The wellbore servicing fluid may comprise water or an aqueous salt solution such as a formate solution. The wellbore servicing fluid may also comprise clay such as montmorillonite and attapulgite clay.

摘要： Methods of reducing sag include combining a cystol ester compound with a non-aqueous fluid and particles to reduce sag in the resulting fluid composition without significantly increasing the viscosity of the fluid composition. The fluid composition comprises the non-aqueous fluid, the particles, and the cystol ester compound. Suitable cystol ester compounds include cystol ester and derivatives of cystol ester having mono-, di , or tri- substituted aromatic compounds as substituents. The non-aqueous fluid may comprise an invert emulsion, diesel oil, mineral oil, an olefin, an organic ester, a synthetic fluid, or combinations thereof. Further, the fluid composition may be used as a wellbore servicing fluid such as a drilling fluid. The particles may comprise a weighting agent, e.g., barite, galena, hematite, dolomite, calcite, or combinations thereof. The fluid composition may also include organophilic clay.
