The OGA estimates that there are some 3.8 trillion cubic feet (tcf) of remaining gas resources within the Southern North Sea (SNS), inclusive of infill opportunities, undeveloped discoveries and prospects.
Tight gas reservoirs are often disregarded as both high cost and high risk. License holders tend to focus their resources on opportunities that are less complex, have lower development costs and higher recovery factors.
OGA’s Tight Gas Strategy sets out a high-level overview. The successful implementation and delivery of this Tight Gas Strategy aims to help deliver tight gas developments across the SNS in support of the MER UK Strategy and OGA’s objectives and priorities within the Corporate Plan.
Beyond the immediate benefits, the development of tight gas opportunities also has the ability to extend the economic life of remaining infrastructure and thereafter stimulate field redevelopments, as well as, marginal pools. Further tangible benefits may also be derived by the local supply chain through the stimulation of activity, as well as, building local capability and expertise in tight gas.
The OGA’s tight gas ambition is to:
- Drive the economic development of some 3.8 tcf from tight gas reservoirs across the SNS
- Support existing tight gas projects and ensure readiness for future projects
- Support collaboration to reduce both costs and risks by sharing knowledge and expertise
- Identify and promote opportunities to campaign activities across licences and drive economies of scale
- Ensure appropriate technology is developed and deployed to support the economic recovery of tight gas, consistent with demand
The eight-step implementation programme maps out a range of activities intended to deliver the OGA’s tight gas ambition:
- Existing tight gas developments
- Future tight gas developments
- Workshops and industry partnerships
- Technology development and deployment
- Knowledge sharing and best practice
- Co-ordinating the supply chain
OGA, with EEEGR, ran a Tight Gas Hackathon in May 2017. A copy of the output report can be found here.
