摘要： A method of recovering oil from a subterranean oil reservoir by waterflooding in which at least a portion of the injected water contains an anionic surfactant comprising a hydrocarbyl hydroxyalkane aminoalkane sulfonate. The hydroxy group is in the 4- or 5-position with respect to the sulfonate group. This surfactant is stable in the presence of high concentrations of divalent metal ions. Thus, this process is applicable in those situations in which the reservoir waters and/or the waters employed in formulating the flooding medium exhibit high divalent metal ion concentrations.

摘要： Various water-soluble additives, either alone or in various combinations, for use in water-based clay drilling fluids. The additives are an acrylate polymer, an acrylate propylene glycol copolymer and three structurally different sulfonate amide polymers. One of the sulfonate amide polymers is a terpolymer consisting of a random distribution of units of the formulae ##STR1## wherein R.sub.1 and R.sub.2 are the same or different and each is hydrogen, methyl, or ethyl, and X.sup.+ is a cation. A second sulfonate amide polymer is a copolymer consisting only of a random distribution of units (a) and (b). The third sulfonate amide polymer is a copolymer consisting of 2-acrylamido-2-methyl propane sulfonic acid and acrylamide. The acrylate polymer is of the formula ##STR2## while the acrylate propylene glycol copolymer is of the formula ##STR3## Drilling operations using a drilling fluid containing these compositions can be carried out at pH levels from about 8 to 11.5 and at temperatures up to about 220.degree. C. The use of the above compositions in a water-based clay drilling fluid results in a reduced fluid loss rate.

摘要： The present invention relates to a process for the substantial reduction of hydrogen sulfide formation during retorting of oil shale by previously treating the oil shale under mild oxidative conditions to passivate the pyrite present in the oil shale. The oxidation of the oil shale under mild oxidative conditions results in the reduction of hydrogen sulfide formation during retorting without a decrease in the amount of oil produced.
