    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： A bituminous composition comprising a bitumen emulsion in an amount from about 2% to about 10% by total weight of the bituminous composition, and aggregate in an amount from about 90% to about 99% by total weight of the bituminous composition, wherein the bituminous composition is at a temperature range of about 50° C. to about 140° C. The bitumen emulsion comprises hard bitumen in an amount from about 50% to about 75% by total weight of the bitumen emulsion, the hard bitumen being characterized by a penetration number of about 100 dmm or less at 25° C. as determined according to the AASHTO Method T49, and an emulsifier in an amount from about 0.05% to about 2% by total weight of the bitumen emulsion, the emulsifier having a Hildebrand solubility parameter of at least of about 19 (MPa)½. Also disclosed are the methods of producing and using such bituminous compositions.
