- Reabold-backed Rathlin Energy is beginning preparatory work for a £2.5m recompletion, stimulation and testing programme at the West Newton A-2 well in East Yorkshire.
- The work is intended to overcome reservoir damage that hampered earlier testing and establish whether the field’s estimated 197.6bcf of 2C recoverable gas resources can support commercial development.
- Reabold is separately assessing a behind-the-meter data centre powered by West Newton gas, expanding an earlier proposal to use onsite generation for bitcoin mining.
Reabold Resources is moving ahead with a £2.5m work programme at its West Newton gas discovery in East Yorkshire as it examines whether the undeveloped field could also provide dedicated power for data centre infrastructure.
Operator Rathlin Energy has authorised initial spending on access-road improvements and long-lead equipment ahead of the recompletion, stimulation and testing of the West Newton A-2 well.
Final engineering and contract awards are under way, with Rathlin planning to install a new completion string before conducting a reservoir stimulation and subsequent well test.
The programme is expected to cost around £2.5m gross before contingency. Reabold, which has a 69.9% economic interest in the PEDL183 licence, said its share is funded following a £4.16m equity raise earlier this year.
The work represents the most consequential operational test at West Newton for several years. WNA-2 was drilled in 2019 to a depth of 2,061 metres but subsequent analysis indicated that drilling and earlier treatments had damaged permeability close to the wellbore, limiting the reservoir’s ability to flow.
Independent consultant RPS subsequently estimated gross technically recoverable 2C resources of 197.6 billion cubic feet of sales gas and 593,000 barrels of liquids across West Newton. Those volumes are contingent resources, however, rather than booked reserves, and commercial production still depends on demonstrating viable flow rates and establishing an economic development plan.
Reabold co-chief executive Stephen Williams described the latest work as “a significant operational milestone” towards unlocking the field.
“We remain highly confident in the strategic value of West Newton, given the scale of the resource, its onshore location and the growing importance of enhancing the UK’s domestic energy security,” he said.
Stimulation targets damaged reservoir
The planned treatment is specifically intended to bypass damage caused during previous drilling.
Rathlin’s technical work concluded that the Kirkham Abbey Formation is particularly sensitive to water-based fluids, which can mobilise material within the reservoir and reduce permeability. The Environment Agency’s permit documents say previous acid treatment had also failed to improve flow sufficiently.
The new programme will instead inject up to 85 cubic metres of gelled hydrocarbon fluid and sand proppant to create and hold open fractures around WNA-2.
The Environment Agency describes the treatment as a reservoir stimulation or proppant squeeze. It works on the same physical principle as hydraulic fracturing, by injecting fluid above the rock’s fracture pressure, but the volumes are far below the statutory UK definition of associated hydraulic fracturing, which requires more than 1,000 cubic metres in a single stage or 10,000 cubic metres overall.
The regulator approved a variation to Rathlin’s environmental permit in February after public consultation, concluding that the proposed activity would not present a significant risk to groundwater. The permit still requires relevant pre-operational conditions to be met, including regulatory oversight of the hydraulic fracture plan.
The operation has nevertheless faced sustained local opposition. East Riding of Yorkshire councillors voted against the fracturing proposal in April, while a local campaigner filed a High Court challenge in May seeking to overturn the Environment Agency’s permit decision.
Rathlin has said it will establish a community benefit fund associated with the project.
From bitcoin mining to AI infrastructure
The more novel element of Reabold’s latest strategy is the proposal to consume some West Newton gas at the wellsite rather than send it directly into the gas network.
A feasibility study is now examining co-located power generation and data centre infrastructure, allowing gas to be converted into electricity behind the meter.
Williams said growing AI demand had made access to scalable and reliable electricity “a key constraint”, adding that West Newton could offer an additional route to monetising the field alongside conventional gas production.
The idea is an evolution of plans announced in August 2025, when Rathlin signed a non-binding agreement with US company 360 Energy to investigate using gas from West Newton to power modular bitcoin-mining facilities. Reabold later created KryptoByte, a subsidiary intended to monetise stranded gas through computing infrastructure.
The latest announcement shifts the emphasis towards conventional data centres, potentially giving the concept greater relevance to Britain’s rapidly expanding AI infrastructure market.
There is a genuine power bottleneck. The government’s Compute Roadmap estimates the UK will require at least 6 GW of AI-capable data centre capacity by 2030, around three times existing capacity, with demand potentially rising considerably further. Ofgem is meanwhile consulting on tougher requirements for data centre grid connections to clear speculative projects from an increasingly congested queue.
Behind-the-meter generation could theoretically shorten the wait for grid capacity, but it also raises questions around emissions and the long-term compatibility of dedicated gas generation with the UK’s clean-power objectives. Reabold has not yet disclosed the proposed data centre’s size, generation technology, emissions profile, customer base, capital requirement or planning route.
