Enhanced Oil Recovery Patents – 2016 (Part 2) Radiation-Assisted Oil Recovery

Enhanced oil recovery techniques can loosely be grouped into methods conducted at ambient temperatures and those at high temperature. Ambient temperature methods include techniques using water flooding, solvent or surfactant injection, and cold heavy oil production with sand (CHOPS). High-temperature techniques function by heating recoverable material in the reservoir to lower its viscosity and improve flowability. Such techniques typically use steam, i.e., steam injection in various ways, although radiation assisted oil recovery would also fall into this group. However, while conventional heat treatments using steam are effective, they can sometimes result in a wastewater stream that is not desirable. While radiation techniques may additionally utilize other injectable streams, they need not rely on a separate heat-input stream to transfer heat, so typically don’t generate the wastewater streams characteristic of steam injection.
