Schlumberger has more than 80 years of experience mapping, measuring, and modeling underground rock formations. The technologies we have pioneered and developed to explore, characterize, and produce hydrocarbon resources have been applied by Schlumberger Carbon Services to form a solid foundation to address the challenges of storing CO2 underground safely, reliably and efficiently. Since the mid-1990s, Schlumberger has directed R&D efforts towards this new frontier, investing substantially to innovate, adapt and patent technologies specifically for use in CO2 storage projects. Schlumberger Carbon Services has been involved in over 80 carbon capture and storage (CCS) projects around the world and this participation, in many different geological contexts, has provided us with a detailed understanding of the various challenges.
Examples of these projects include:
The Midwest Geological Sequestration Consortium (MGSC), led by the Illinois State Geological Survey in partnership with the Archer Daniels Midland Company (ADM) and Schlumberger Carbon Services, is injecting one million tonnes of CO2 over a three-year period into a geological formation more than two kilometers below ground level. Injection started in November 2011 and is already at the halfway point. In addition, this same team is in the process of constructing another injection site one mile away to inject one million tonnes per year for four years into the same reservoir, with injection starting in 2014.
Schlumberger is providing a series of cross-disciplinary studies to evaluate a geological site for potential CO2 storage. The work includes evaluating the local geology, building reservoir models, conducting geomechanical analysis, assessing risks and developing a monitoring program.
The world’s first industrial-scale CCS operation is under way at Statoil’s Sleipner field off the coast of Norway. Schlumberger is providing key services, particularly our advanced 4D seismic monitoring, which, through time, records the evolution of the CO2 in the subsurface.
Schlumberger provided technologies and project management personnel for Australia’s first demonstration of deep underground storage of CO2—the CO2CRC Otway project. This first phase conceived and executed over six years (2005—2010) injected over 65,000 tonnes and had an innovative and comprehensive monitoring program to track the injected CO2. This project also provided valuable input to the Victorian State Greenhouse Gas Legislation. Schlumberger continues to provide technological services and modeling software as the Otway Project researchers evaluate the data and define the ne
One response to concerns that human activity is influencing climate has been to remove the CO2 from emissions created when carbon-based fuels are burned and sequester it deep underground.
