The SCCS CO₂-EOR Joint Industry Project (JIP) has published the results from a collaborative programme of work to develop an understanding of CO₂-Enhanced Oil Recovery (EOR), with the aim of creating a commercial use for CO₂ captured from power plants and industry. The project is led by SCCS partners and funding has been provided by the Scottish Government, Scottish Enterprise, 2Co Energy Limited, Nexen and Shell.

CO₂-EOR technology, which has been used in North America for decades, involves injecting CO₂ into partially depleted oilfields deep beneath the seabed to force out additional volumes of oil, with the majority of the injected CO₂ remaining permanently stored deep underground. Although to date there has been no supply of CO₂ to support implementation of industrial scale CO₂-EOR in the North Sea, the large-scale development of Carbon Capture and Storage (CCS) could change this.

This project has focused on addressing issues, which are of major importance to project developers looking to link CO₂-EOR in the North Sea with CCS projects. It has been undertaken as a series of work packages in two phases.

A total of 17 detailed reports have been produced covering a wide variety of topics. These are divided into six subcategories and are available to download below. The summary report brings all 17 pieces of work together in one publication.
