Recent time-lapse seismic data show no indication of leakage at the Sleipner co2-injection site
bookPart
Injection of CO) into the Utsira Sand, a saline aquifer at the Sleipner site in the North Sea, has been in progress for more than seven years, with an annual rate of approximately one million tonnes. This project is considered as the first industrial-scale, environmentally driven CO, injection project in the world. In consequence, a European research project (initially called SACS succeeded by the ongoing CO2STORE) has been organized around it, with special focus on monitoring and simulation. To that end, four seismic surveys have so far been acquired, one prior to injection, and three afterwards in 1999, 2001 and 2002. In this paper results from the 2002 survey will be presented for the first time and compared to findings from the previous surveys. The major conclusion is that there are still no indications of CO, leakage to levels shallower than the Utsira Sand.
