SAFERCCS: Sustaining fluid-flow and Assessing Feldspar solubility Enhancement Reactions in CCS reservoirs

The Acorn CCS project, part of the Scotland Hub, aims to inject supercritical CO₂ into a depleted Captain Sandstone hydrocarbon reservoir, to be stored indefinitely. Productivity and safety of CCS relies on our ability to flow CO₂ fluids into rocks and prevent it from leaking out. Our capability to predict (and maintain) fluid-flow during injection requires knowledge of micro-scale reservoir properties and how injected fluids might mechanically and/or chemically alter this microstructure and impact CCS project efficiency.
