Jersey Oil & Gas (JOG), a key player in the UK North Sea oil and gas sector, has voiced concerns regarding the decelerated progress of its significant Buchan Horst development. The company attributes the slowdown to ongoing uncertainty surrounding the UK Government’s regulatory and fiscal policies for the North Sea.
The Buchan Horst project, situated approximately 115 kilometres north-east of the Aberdeenshire coastline within the Greater Buchan Area (GBA), is considered a “huge opportunity” for the company. This initiative represents a redevelopment of the original Buchan field, which ceased production in May 2017 due to limitations with its floating production vessel.
In its recent update, Jersey Oil & Gas highlighted significant progress made towards “monetising” the Greater Buchan Area. However, it noted a “frustratingly” slow momentum over the past year. The company stated: “Following the significant progress that has been made by the company towards monetising the Greater Buchan Area, the last year has frustratingly seen momentum slowing as a result of the Government’s consultations on the future regulatory and fiscal direction of the UK North Sea.”
Despite these headwinds, JOG maintains a strong market position. The company asserted: “Despite this, the company remains well positioned as one of the leading UK-listed small-cap oil and gas companies, with a high-quality development portfolio and the funding to deliver on its organic growth plans.”
The Buchan Horst development, in which Jersey Oil & Gas holds a 20% interest, is a joint venture with Neo NEXT+, which has a 50% stake and serves as operator, and Serica Energy, holding 30%. The company emphasised that the potential for the project to generate long-term shareholder value is “well understood and securing sanction for this project represents a huge opportunity”.
Government consultations on the North Sea’s future regulatory and fiscal framework concluded in late 2025, aiming to provide clarity for future investment decisions. JOG acknowledged this, stating: “While the end of the Government consultations in late 2025 helped provide additional clarity on the framework within which future investment decisions can be assessed, it is clear that the industry as a whole is still digesting the outcomes.”
A critical factor influencing the project’s timeline is the replacement of the Energy Profits Levy, often referred to as the “windfall tax.” This levy is expected to be succeeded by an “oil and gas price mechanism” by March 2030, or potentially earlier under specific market conditions. The industry has advocated for an earlier implementation of this new mechanism to encourage investment.
Jersey Oil & Gas also highlighted the importance of regulatory precedents set by other North Sea projects. The company stated: “Positive conclusions in respect of the protracted environmental and regulatory approval processes for the North Sea’s Jackdaw and Rosebank developments will inevitably help inform the optimal route forward for subsequent UK projects like Buchan.” Both Jackdaw and Rosebank have faced significant environmental and regulatory scrutiny, including legal challenges concerning their emissions assessments.

Financially, JOG reported robust figures for year-end 2025, with cash reserves of £11 million, no debt, and an annual cash burn rate below £1.5 million.
The Greater Buchan Area is estimated to hold over 100 million barrels of oil equivalent in gross resources, and JOG’s 20% interest is fully funded through prior farm-out agreements, including milestone payments totalling over $25 million. The company affirmed its focus on “unlocking the organic value of the GBA,” alongside utilising its existing UK tax allowances of more than $100 million through strategic asset acquisitions.
