Abstract
852,769. Treating oil-bearing strata. OIL RECOVERY CORPORATION. Feb. 20,1959, No. 5939/59. Class 85. A subterranean formation is treated for oil recovery by disseminating within the formation, by CO 2 carbonated water at a pressure of CO 2 of at least 400 pounds per square inch, a surface active agent preferably non-ionic. The agent may be introduced separately, or simultaneously with the carbonated water, as a liquid or in solution, suspension or dispersion, the carbonated water being used as the drive; or the materials may be introduced intermittently or in alternation. Suitable non-ionic agents are obtained by reaction of a hydrophobic hydroxy compound, such as phenol or alcohol, with several moles of an alkylene oxide, principally ethylene oxide or propylene oxide. Alkylene oxide reaction products with higher fatty acids or fatty acid esters; phosphoric acid esters of polyethylene glycol; low order condensation products of polyhydric alcohols with polybasic water-soluble acids such as glycol tartrate, glycerol citrate, esterified with stearic acid; higher fatty acid reaction products with alkylolamines such as coconut fatty acids with diethanolamine; and saponins are stated to be suitable surface agents. Polyoxyethylene sorbitan monostearate, as illustrating a preferred group of non-ionic surface agents soluble in water, dilute acids and alkalis, alcohol and toluol, but insoluble in mineral oil, is used in carbonated water in the proportion 0À1% as a drive at 900 pounds per square inch in unconsolidated sand carrying naphthenic crude oil, the oil content of the sand being reduced from 17À1 to 8À8% of the pore space. The solubility of CO 2 in the solution containing the wetting agent may be modified by adding a salt or salts or other organic or inorganic compound, a large number of suitable substances being mentioned. Carbonated water or brine may be used as the only drive, or it may be used with other drives, e.g., a COz drive. Dry CO 2 may be introduced first, followed by carbonated water and then by an air, methane or other fluid drive. The wetting agent is removed from the effluent and returned to the inlet well. The solubility at high pressures of gaseous hydrocarbons, particularly lower paraffinic hydrocarbons in.crude oil, is stated to be increased by CO 2 . In an example, a formation was treated with CO 2 of at least 300 pounds per square inch, or preferably 600-1400 pounds per square inch, the effluent containing CO 2 and hydrocarbons which are both gaseous and liquid at 0‹C and 760 mm., and after liquids are condensed from such effluent, the gas residuum is recycled as the gaseous medium for contacting the hydrocarbon oils.
