... Abstract When oil is produced by water injection sulfide formation (souring) can be stimulated. Souring is often caused by sulfatereducing bacteria (SRB), which oxidize organic carbon (oil organics) with sulfate in the injection water to CO 2 and sulfide. As a result H2S concentrations...

... factors that control the effectiveness of ASP flooding. The effects of alkali, surfactant, polymer and oil properties on IFT were previously studied. This paper addresses the effect of injection water quality on IFT of ASP/crude oil. This paper analyzes the inorganic ion compositions and organism...

... wells is above 90%. To control water conformance, a large volume of weak gel treatment was proposed. Based on the specific features of offshore oilfields, such as small space of platform, high salinity on injection water, a new weak gel was developed. This paper introduced the properties of each...

... sulfide (pyrite), calcium carbonate, calcium sulfate, clays, formation fines, oil and bacteria. Sulfate reducing bacteria (S.R.B.) reduce injection water sulfate ions to sulfur ions. As a result, hydrogen sulfide (H 2 S) is produced and water corrosivity is increased. (3) . Sour corrosion allows...
