steam soak

extraction process
Also known as: cyclic steam injection, steam cycling

Quick Summary

The term "steam soak" refers to a thermal method used in petroleum production to recover heavy crude oils that are too viscous to flow easily. This process involves injecting steam into an oil reservoir. The heat from the steam reduces the oil's viscosity, making it more fluid. After the steam condenses and releases its heat, the well is put into production, and the heated oil can be lifted to the surface. This cycle can often be repeated in the same well to maximize recovery.1

Extraction of oils from various sources, such as oilseeds, also involves processes to recover the oil. Mechanical pressing and solvent extraction are common methods. Solvent extraction, often using hydrocarbons like petroleum benzin, is an economical way to recover residual oil from materials that have already been pressed.2
