摘要： A method is disclosed for recovering oil from a subterranean oil-bearing formation wherein a liquid solution in injected into and driven through the formation and oil is recovered from the formation. The liquid solution contains an effective amount of a surface-active agent having the general formula: ##EQU1## or ##EQU2## wherein R.sub.1 is a benzene, toluene, or xylene radical having a linear or branched alkyl substituent containing from 6 to 24 carbon atoms;R.sub.2 is an alkyl, cycloalkyl, alkene or aryl radical containing up to 8 carbon atoms;R.sub.3 is a hydrogen atom, a hydroxyl radical, or an aliphatic radical containing from 1 to 8 carbon atoms;n has a value of 2 or 3;m has an average value of from 1 to 20; andX is a cation.

摘要： One embodiment includes an oil recovery process, more particularly a secondary or tertiary type crude oil recovery process utilizing a drive fluid to move a displacing fluid through a subterranean formation wherein the displacing fluid displaces crude oil therefrom and is driven through the formation by means of the drive fluid. The crude oil recovery process is improved by utilizing as the drive fluid a thickened, transparent, aqueous solution of a water-soluble sulfated, polyethoxylated C.sub.10 -C.sub.18 primary alcohol or alkylated phenol. The displacing fluid is generally an aqueous surfactant solution, a miscible displacing medium or most preferably a microemulsion. In a further embodiment, the water-soluble, polyethoxylated C.sub.10 -C.sub.18 primary alcohol or alkylated phenol is employed as a mobility control agent in a waterflood thereby increasing the sweep efficiency thereof.

摘要： A method for recovering oil from a subterranean formation is disclosed wherein an aqueous surfactant solution is injected into the formation to reduce the mobility of gas in a gas-flooding process. The gas may include hydrocarbon gas, inert gas, carbon dioxide, and steam. The surfactant is represented by the general formula ##STR1## where R is a linear or branched chain alkyl group with n carbon atoms wherein n ranges from 0 to about 18, except that if the gas is steam n ranges from about 9 to about 30;x ranges from 0 to about 20 and y ranges from 0 to about 20, provided x+y does not exceed about 20;R' is a linear or branched chain alkyl group with m carbon atoms wherein m ranges from 0 to 4, except that if the gas is steam m ranges from 1 to 4, with the proviso that the sum of x+y+m is at least one; andeach M.sup.+ is a cation.

摘要： An oil recovery method is disclosed which uses a particular class of alkylaryl sulfonate surfactants. The surfactants are derived from an extracted aromatic feedstock consisting essentially of benzene, toluene, xylenes, and lesser amounts of ethylbenzene, trimethylbenzenes, and tetramethylbenzenes. The aromatic feedstock is then alkylated with linear .alpha.-olefins to favor second-carbon attachment, and sulfonated to result in surfactants having high oil solubilization parameters and whose phase behavior is substantially independent of temperature over 120.degree.-250.degree. Fahrenheit.
