Demonstrating storage of CO2 in geological reservoirs: The Sleipner and SACS projects

At the Sleipner gas field in the North Sea, CO2 has been stripped from the produced natural gas and injected into a sand layer called the Utsira formation. Injection started in October 1996, to date nearly 8 million tonnes of CO2 have been injected without any significant operational problems observed in the capture plant or in the injection well. The Sleipner project is the first commercial application of CO2 storage in deep saline aquifers in the world. To monitor the injected CO2, a separate project called the saline aquifer CO2 storage (SACS) project was established in 1998.
