13 Years Of Safe CO2 Injection At K12-B

Abstract

Since 2004 the feasibility of CO2 injection and storage in depleted natural gas fields has been researched and demonstrated at K12-B, a gas field on the Dutch continental shelf. In total over 100 Kton of CO2 was injected. The entire operation at the K12-B field was completed without any major complications. It can therefore be stated that safe and uneventful underground storage in depleted gas fields is possible. During the many activities taking place at K12-B, numerous techniques were tested and enhanced and many processes, including corrosion tests, investigated. This has helped in assessing other projected CCS projects, such as P18. There is now a proven track record of over a decade of continuous CO2 injection, supported by many risk assessment studies. The findings of this extensive scientific CO2 re-injection research can be showcased and applied to other Carbon Capture and Storage Projects in the world. One year ago the project came to an end. In this abstract we present some of the highlights. © 2018 European Association of Geoscientists and Engineers, EAGE. All rights reserved.
