Heavy Oil

72 result(s) found.

heavy oil  Crude oils with high viscosity (typically above 10 cP), and gravity lower than 22.3° API are classified as heavy oils. These crudes generally require special producing techniques to overcome their high viscosity. This special section in the Oilfield Glossary reflects the growing importance of heavy oil to the E&P Industry, and provides an evergreen, comprehensive listing for major heavy-oil terms. Definitions ranging from API gravity to steamflood to wormhole have been reviewed by technical experts in the domain, with some terms supplemented by high-quality illustrations for clarification.
