Enhanced Oil Recovery Techniques

Enhanced Oil Recovery Techniques is a research topic within Ocean Engineering. Science Explorer counts 37k research works in it since 1950. 9.9% of them reached the world's top 10% most cited for their field and year.

This cluster of papers focuses on the use of advanced imaging techniques such as X-ray computed tomography for pore-scale modeling and analysis in the context of enhanced oil recovery. It explores methods for wettability alteration, the use of nanofluids and surfactants, and the application of foam for improved recovery in porous media and reservoir rocks.
