Oil well production fluid composed of oil and water and containing in excess of 100 ppm water soluble petroleum carboxylates in anionic form dissolved in the water is treated by acidifying the fluid to a pH of 6.0 or lower with a combination of a strong organic acid and a strong mineral acid and then is intimately mixed. The oil and water are separated one from the other. The content of the water soluble organics in the water is thereby substantially transferred to the oil phase. In a second aspect of the invention, water used to extract corrosive compounds to render the oil suitable for fueling gas turbine power plants is acidified to a pH of 6.0 or lower and is thereafter intimately mixed with fuel oil.
Fluide pour l'exploitation de puits de pétrole, renfermant de l'huile et de l'eau, ainsi qu'un excès de 100 ppm de carboxylates pétroliers solubles, sous forme anionique, dissous dans l'eau. Ce fluide est acidifié à un pH de 6,0 ou moins, à l'aide d'une combinaison d'un acide organique et d'un acide minéral forts, puis est soumis à un brassage énergique. L'huile et l'eau sont séparées l'une de l'autre. Les composés organiques hydrosolubles sont ainsi transférés en grande partie dans la phase huileuse. Dans un second aspect de l'invention, l'eau utilisée pour extraire les composés corrosifs et rendre l'huile utilisable comme combustible pour centrales électriques à turbines à gaz, est acidifiée à pH 6,0 ou moins, puis brassée énergiquement avec du mazout.
