Abstract:
1. A method for destruction of organic material in injection water for an injection well, said method making use of: a means for introduction of water in the injection well; and at least one electrochemical cell with associated operating means for in situ electrolytic generation, via radiolysis of water, of at least one reactive oxygen compound; said method comprising: (A) connecting the at least one electrochemical cell to the injection well; (B) conducting said injection water, by means of said operating means, through the electrochemical cell for in situ generation of said at least one reactive oxygen compound, thereby using the injection water as a source material for said radiolysis; and (C) arranging said electrochemical cell for in situ generation of short-lived, free hydroxyl radicals as at least a primary agent resulting from said radiolysis of the injection water, said hydroxyl radicals being a reactive oxygen compound species that will immediately destruct organic material engaged in the injection water.
