To address these uncertainties, a Single Well Injectivity Test was conducted in one of the existing primary production wells. The next step involves conducting the Multi-Well Test to determine interwell recovery performance...

... of the plan. Tracers injection was designed and executed to evaluate the incremental oil production due to ASP injection by using A) change in volume swept between the pilot wells and B) change in oil saturations due to ASP flooding. This paper focusses on the practical aspects of the tracer program execution...

The sensitivity analysis results showed that the initial oil saturation, oil viscosity, porosity, and matrix permeability were the most important parameters affecting improved oil recovery when combined technology applied. The matrix permeability was the most important parameter...
