Enhanced Oil Recovery
OGA's Enhanced Oil Recovery (EOR) Strategy sets out a high-level overview of EOR UKCS opportunities. The importance of encouraging industry uptake of EOR was outlined in the Wood Maximising Recovery review and subsequently EOR is an integral theme of the MER UK Asset Stewardship Board.
Successful EOR can play a significant role in maximising economic recovery from the UKCS by increasing the volume of recovery, extending field life (by as much as 10 years), creating and maintaining jobs, help stimulate field redevelopments and defer decommissioning activities.
EOR Technologies are currently being successfully deployed around the world, usually onshore. Information on various EOR technologies by BP, Chevron, Shell and Statoil can be viewed on their websites.
However, offshore EOR is often unattractive due to being capital intensive and requiring higher operating costs than conventional water flood schemes.
The OGA’s ambition for EOR is to:
- Drive economic development of 250 million boe incremental reserves primarily through polymer EOR over the next decade; work with operators and the supply chain to support existing projects; to ensure readiness for future projects; drive risk reduction by technical and economic improvement
- Demonstrate a proven offshore operation of low salinity EOR by 2021 and encourage EOR evaluations for all new projects
- Advance the next tranche of EOR technologies and develop a roadmap for their economic implementation
In order to create the right conditions to meet this ambition, the following areas are crucial to advance polymer EOR:
- Cost reduction – the creation of a competitive, robust supply chain to improve polymer EOR economics and reduce risk
- Collaboration – share lessons learned to build EOR knowledge and competency in the UKCS and reduce barriers to EOR development at both producing and future fields; collective approaches will be developed to manage the risk profile of EOR developments and mitigate common risks
- Sustainability – identify potential standardisation of EOR-related technologies such as industry standards for testing EOR polymers
The EOR Delivery Programme builds on the EOR Strategy and describes in more detail how and when the near-term priority areas in EOR will be delivered. It takes into account the various obligations and commitments from the MER UK Strategy, the Energy Act and the OGA Corporate Plan, as well as the principles of stewardship outlined in the Asset Stewardship Strategy.
Any arising reports from the EOR Delivery Programme will be provided from this webpage.
Eight-step EOR Delivery Programme
- Existing EOR projects
- MER for future EOR projects
- Workgroups and industry partnerships
- Technology development and deployment
- Creating value – improving economics
- Advance next EOR and support CO2 storage
- Knowledge management
- Communication and stakeholder plans
The activities in the EOR Delivery Programme will be monitored by a joint industry task group made up of members from BP, Chevron, OGA, Shell and Statoil and reviewed annually by the MER UK Asset Stewardship Board and updated as necessary.
The Oil and Gas Authority (OGA) has published a comprehensive lessons learned document to help encourage oil and gas operators to use polymer technology to enhance oil recovery (EOR) from UK oil fields. See here for details
