| titleOfInvention |
Process for stimulating a well with a saline surfactant sulfate, alkanol and acid system |
| abstract |
The injectivity of an oil-containing reservoir is increased by injecting successive portions of a solution or slightly turbid dispersion of reservoir-tailored amounts of polyalkoxyalcohol sulfate surfactant and lower alkanol in highly saline aqueous liquid and a reservoir acidizing solution. |
