The FAWAG (Foam Assisted Water Alternating Gas) project is a full-scale demonstration by Saga Petroleum of the use of foam for gas mobility control. The foam injection started in the Central Fault Block (CFB) of the Snorre field in August 1998, after a two-year planning period, and many years of active research on foam. The first phase of the project, a Surfactant Alternating Gas (SAG) injection was completed in late November 1998. A co-injection phase was carried during January to June 1999. Approximately 1800 tons of commercial grade surfactant was used in this project.
