Combined RF EM/Solvent Treatment Technique: Heavy/Extra-heavy Oil Production Model Case Study(Abstract)

摘要

The present paper discusses the technique of radiofrequency (RF) electromagnetic (EM) heating of an oil-bearing layer combined with solvent injection, aimed at increasing heavy and extra-heavy oil recovery rate. Such combined technology expands the displacement area and allows a deeper heating of the layer. This method increases the technical and economic efficiency of field development by treating a producing well in three stages. At the first stage, the well operates as in injector to inject a solvent with simultaneous RF EM exposure. At the second stage, the well is suspended to 'stay' without any treatment. Finally, the well is re-commissioned to produce from the layer.
