    摘要: Disclosed are drilling fluids suitable for use in connection with oil well drilling. The drilling fluids of the invention include in one embodiment a liquid base, an alkyl glucoside, such as methyl glucoside, and a borehole stability agent that includes a maltodextrin, a carboxyalkyl starch, a hemicellulose-containing material, or a mixture of the foregoing. In another embodiment, the drilling fluid includes a liquid base and desugared molasses solids, preferably in combination with an alkyl glucoside and more preferably in further combination with one of the aforementioned borehole stability agents. The drilling fluids of the invention surprisingly have a reduced tendency to swell shale as compared with known drilling fluids. Also disclosed are a drilling apparatus and process. The drilling apparatus includes a drill string, which may be conventional, that is fluidically coupled to a source of drilling fluid, the source of drilling fluid including the drilling fluid of the invention. The process of the invention includes the step of circulating the drilling fluid of the invention through a drill string during borehole drilling.

    摘要: Disclosed is a method for inhibiting the freeze-clumping of an aggregate material, such as coal. The invention contemplates applying to the coal an anti-icing material, the anti-icing material comprising molasses solids, such as desugared sugar beet molasses solids or sugar cane molasses solids and/or an aqueous solution of glucose, fructose, or of DP 2-5 polymers thereof. The anti-icing material has a viscosity sufficient to adhere to the aggregate material to an extent suitable to inhibit freeze-clumping thereof. Also disclosed is a clump-inhibited aggregate material that comprises an aggregate of units of a material in combination with an anti-icing material as heretofore described.

    摘要: Disclosed are dust suppressant and aggregate stabilization compositions. In accordance with the subject disclosure, hemicellulose is used as a dust suppressant and/or as a stabilization composition for aggregates such as a road bed or soil field. Other ingredients may be used in a composition in conjunction with hemicellulose. For instance, a lignin compound may be used to enhance dust suppression and/or aggregate stabilization. A surfactant may be used to decrease the viscosity of the composition. A crosslinking agent may be used to enhance the water resistance of the composition. A chloride salt may be added to increase the hygroscopicity of the composition.

    摘要: Disclosed are drilling fluids that include carboxyalkylated corn hulls in an amount effective to inhibit fluid loss from a wellbore formation. The carboxyalkylated corn hulls are heat stable and surprisingly effective at inhibiting fluid loss. Also disclosed are a drilling apparatus and a drilling process.
