A process is disclosed for enhancing oil recovery in oil-containing reservoirs formed of water-wet sand. The process involves placing oil-wet sand in the near-bore region of a production well. The process can be used to provide an improvement to both a conventional pressure driven fluid drive process and a conventional steam-assisted gravity drainage process. In the fluid drive process, the drive fluid is injected intermittently.
