Topic: Geophysics for CCS – Repurposing a Depleted Reservoir for the Energy Transition
The Acorn Carbon Capture and Storage (CCS) project aims to inject CO2 at an initial rate of some 324,000 tonnes/yr into the depleted Goldeneye field reservoir in the North Sea through the decarbonisation of the St. Fergus gas terminal in Aberdeenshire and builds on an extensive bed of work undertaken for previous iterations of the project. This presentation will outline the geoscience work required to support the project decisions, emphasising the similarities and strong skills overlap between CCS and conventional field development, which include seismic interpretation, static modelling, geohazard analysis and well planning, as well as supporting dynamic modelling. These elements feed into capacity and injectivity assessments, containment evaluations and monitoring plans, which all support key elements of the project.
