Key words: hydraulic fracturing, residual oil reserves, oil recovery factor, sweep efficiency, displacement efficiency, light absorption coefficient.
This paper presents integrated analysis of hydraulic fracturing efficiency in residual oil displacement. Enhanced oil recovery methods increase both oil displacement efficiency and sweep efficiency. The authors propose integrated analysis of well flow rates and light absorption coefficient variations to evaluate the effect of fracturing technology on reservoir performance. This paper also presents comparative analysis of well performance and light absorption coefficient variation data. The analysis has been performed for Devonian terrigenous deposits of the Romashkinskoye field.
