The small pools resource base has been estimated at some 363 discovered fields between 3 and 50 million barrels of oil equivalent (mmboe) distributed across the UKCS.
Enhanced recovery from small pools
Our Small Pools Solution Centre builds on all the work done by the UK Technology Leadership Board theme group identifying the issues and barriers to economic development. We seek to identify the technology requirements across the basins and define appropriate solutions per development area. We recognise that individual basin areas have a variety of specific issues to overcome, and these are not always common across all areas of the UKCS.
Our target is the development of currently fallow fields and accelerated investment in applied technologies applicable to ‘marginal field developments’. Within the first three years, working in partnership with the Oil and Gas Authority, we will seek to deliver:
- a cost reduction of 25% -30% of capital costs with benefits flowing through the full field lifecycle
- a portfolio of 3-5 developments on-going
- 1-3 clusters under development
Tieback of the Future
Our ‘Tie-back of the Future’ initiative aims to both half the cost and half the time to develop small pools. This would make an additional 400 million barrels economic.
The initiative brings together 25 operators, supply chain firms and technology developers to transform the approach to developing marginal fields. Creating a circular economy, whereby subsea equipment is designed for disassembly and reuse, is at the heart of the initiative.

Applied technology solutions
We are working to identify a technology road map for each basin within the UKCS. These maps will then be consolidated to create a single map of the potential resources. Our initial focus is on engaging with key stakeholders; building relationships with operators and leading service companies.
The Technology Leadership Board has compiled an initial summary of the key technology issues or barriers to the development of the marginal fields that have been grouped under the following headings:
- fluid commingling
- differential pressure
- gas disposal
- low energy reservoirs / difficult fluids
We have started a full analysis of the outputs from the TLB work group.
Working in partnership
We recognise there are several operators with whom a close working relationship should be mutually beneficial. These are primarily those operating companies that hold undeveloped discoveries and have reserves under production. The operating companies are Shell, Conoco Phillips, Nexen, Total, Apache, BP and Premier Oil. This list is not exhaustive but does reflect our current thinking.
The role of the Oil & Gas Authority with respect to the unlicensed discoveries is also pivotal to the success of the Small Pools Solution Centre.
Delivering economic benefit
There are approximately 363 small pools of hydrocarbons in the UKCS, defined as discoveries of oil or gas accumulations between 3 and 50mmboe, with total estimated recoverable reserves of 3.4 bnboe.
