    • 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.
    • 降低下垂的方法包括将鲸蜡酯化合物与非水性流体和颗粒组合以减少所得流体组合物中的下垂,而不显着增加流体组合物的粘度。 流体组合物包含非水性流体,颗粒和鲸蜡醇酯化合物。 合适的癸二醇酯化合物包括具有单取代基,二取代或三取代芳族化合物作为取代基的胱抑醇酯和二醇酯的衍生物。 非水性流体可以包括反相乳液,柴油,矿物油,烯烃,有机酯,合成流体或其组合。 此外,流体组合物可以用作井筒维修流体,例如钻井液。 颗粒可以包括加重剂,例如重晶石,方铅矿,赤铁矿,白云石,方解石或其组合。 流体组合物还可以包括亲有机粘土。
