    摘要： An oil-based reservoir drill-in fluid (RDF) comprising an oil-based RDF additive that includes a blend, reaction product, or mixture thereof, of (A) one or more hydrophobizing component or agent (e.g., an amine or amide containing compound), and (B) one or more phenolic material or composition comprising phenolic polymers or salts thereof (e.g., lignin, a lignin derivative, or mixture thereof), which may be utilized as an oil-base RDF additive or as a component of an oil-based RDF additive, is described. A method of drilling a reservoir section of a wellbore with the oil-based RDF, the method including the oil-based RDF additive.

    摘要： An evaporative emission control canister system comprises an initial adsorbent volume having an effective incremental adsorption capacity at 25° C. of greater than 35 grams n-butane/L between vapor concentration of 5 vol % and 50 vol % n-butane, and at least one subsequent adsorbent volume having an effective incremental adsorption capacity at 25° C. of less than 35 grams n-butane/L between vapor concentration of 5 vol % and 50 vol % n-butane. The evaporative emission control canister system has a two-day diurnal breathing loss (DBL) emissions of no more than 20 mg at no more than 210 liters of purge applied after the 40 g/hr BETP butane loading step.

    摘要： Emulsifier particles and methods for making and using same. The emulsifier particles can include an alkali metal salt or an alkaline earth metal salt of a carboxylic acid terminated fatty amine condensate, an alkali metal salt or an alkaline earth metal salt of a modified tall oil, or a blend of an alkali metal salt or an alkaline earth metal salt of a carboxylic acid terminated fatty amine condensate and an alkali metal salt or an alkaline earth metal salt of a modified tall oil. The emulsifier particles can have a BET specific surface area of about 0.3 m2/g to about 1 m2/g. The method for making the emulsifier particles can include reducing a size of an emulsifier solid via a mechanical attrition process to produce the emulsifier particles.

    摘要： A composition containing a blend, reaction product, or mixture thereof, of (A) one or more hydrophobizing component or agent (e.g., an amine or amide containing compound), and (B) one or more phenolic material or composition comprising phenolic polymers or salts thereof (e.g., lignin, a lignin derivative, or mixture thereof), which may be utilized as a drilling fluid additive or as a component of a drilling fluid additive, is described. A method of making the composition or drilling fluid additive is also described. Further, a drilling fluid containing the drilling fluid additive or composition is described.
