Data acquisition and interpretation, Geomechanical and microseismic interpretation, geomechanical integrity of storage site. Client: Gassnova, BP, Statoil, Sonatrach NGI Reference: Sleipner CO 2 storage site Sleipner is located in offshore Norway, central North Sea. CO 2 injection was started 1996 and is on-going with an injection of about 0.85 million tonnes per year. As a member of the SUCCESS FME Centre, NGI had the following activities for Sleipner: Analysis of geophysical data (seismic, EM, gravity) Modelling of plume migration and stress change due to injection Client: SUCCESS industry partners (CGG, Dea, Dong Energy, ConocoPhillips, Lundin, Octio, Statoil, Store Norske) and the CLIMIT Program of the Research Council of Norway NGI Reference: Snøhvit CO 2 storage site Snøhvit is a gas field in the Barents Sea, offshore Norway. CO 2 storage was started in 2008 and is on-going. The CO 2 is captured from the natural gas on the island of Melkøya, northern Norway. The captured CO 2 is transported via pipeline back to the Snøhvit field offshore where it is injected into an offshore storage reservoir. As a member of the SUCCESS FME Center, NGI had the following activities for Snøhvit: - Analysis of CO 2 injection data and injection scenarios for Tubåen formation - Geomechanical investigation and the risk of fault re-activation due to CO 2 injection Client: SUCCESS industry partners and the CLIMIT Program of the Research Council of Norway NGI Reference:

The vision is to make Longyearbyen CO 2 neutral by capturing tonnes of CO 2 produced by a local coal-fired power plant and storing in a saline aquifer about meters underground. Standard and advanced rock testing program Analysis of water injection tests Geomechanical studies of reservoir, cap rock and the risk of containment breach Geophysical studies to develop CO2-related rock physics, including naturally-fractured rock Client: University Center at Svalbard, SUCCESS partners and the CLIMIT Program of the Research Council of Norway NGI references: , Decatur CO 2 storage site The Illinois Basin Decatur Project (IBDP) aims to validate the capacity, injectivity and containment of the Mount Simon Sandstone, which represents the primary carbon storage resource in the Illinois Basin and the Midwestern United States. Carbon dioxide was captured from the ADM corn-to-ethanol plant in Illinois and injected in a nearby storage site from November 2011 to November Over this time period about 1 million tonnes of CO 2 was injected and stored.

SSC Ramore -Subsurface Storage of CO 2 - Risk Assessment, MOnitoring and Remediation To evaluate potential CO 2 leakage from subsurface storage, SSC-RAMORE focused on the geochemical interaction of CO 2 with caprocks and with engineered materials in wells, as well as with the corresponding changes in geo-mechanical properties. Furthermore, the project carried out simulations of injected CO 2 in reservoir models to improve monitoring of CO 2 reservoirs, and developed a methodology for risk assessments of CO 2 storage in the subsurface. - Flow of supercritical CO 2 in reservoir rocks and monitoring with CT scanner - Capillary entrance of supercritical CO 2 into shale samples - Investigating geochemical effects of CO 2 on cement and cap rocks Client: Research Council of Norway (CLIMIT Program) NGI reference: Matmora II -Geological Storage of CO 2 : Mathematical Modelling and Risk Assessment The primary objective of the project was to develop methods for modelling and simulating leading-order effects of pertinent flow dynamics of CO 2 in appropriate geological formations for CO 2 storage. Secondary objectives were the quantification of thermal and mechanical effects and effect of pressure on reservoir/ caprock integrity. Tore Ingvald Bjørnarå completed his PhD study entitled "Model development for efficient simulation of CO 2 storage". The focus was on the development of a simplified mathematical model for efficient simulation of the essential processes, particularly two-phase fluid flow, temperature change and stress change, to evaluate suitability and integrity of the reservoir and the sealing formations. NGI reference: CO2 bypass of reservoir-caprock systems An exhumed reservoirs in Utah, USA, showing evidence of CO 2 accumulation in geological history offer a unique possibility to supplement our knowledge on leakage processes observed along faults and fractures, and to understand the relevant spatial and temporal scales of CO 2 migration in order to support safe CO 2 injection operations.
