CO2-EOR has the potential to bring benefits for the UK offshore industry by improving recovery from depleted oil fields using CO2 captured from power plants and industry, says project leader Scottish Carbon Capture & Storage.
Other joint industry project partners include the Scottish government, Scottish Enterprise, 2Co Energy and Nexen Petroleum UK.
The project is focused on gaining a better understanding of the use of CO2 in EOR operations, with the aim of extending the life of North Sea oil fields using CO2 captured from large emitters — such as power plants and industrial facilities — and permanently storing the greenhouse gas in offshore oil reservoirs.
The first phase of research has investigated issues that could affect the development of CO2-EOR linked with CCS projects, such as the legal and regulatory frameworks and taxation. Various fiscal models are being explored, alongside an investigation of how CO2-EOR is perceived by government, regulators, NGOs, the public and other stakeholders.
In the project’s second phase, the partners will now focus on a range of research, including reservoir modeling, further analysis of fiscal arrangements and the carbon balance of CO2-EOR operations, as well as public engagement.
Enhanced oil recovery is a promising market for CO2 captured from electric power generation as EOR’s demand for the gas exceeds available supplies, according to a March report from analysts Visiongain.
