About Zennor Petroleum

Zennor Petroleum is an independent UK based oil and gas company specialising in the appraisal, development and production of hydrocarbons on the UKCS. Zennor currently has production of circa 5,000 boe/day.
Our core focus is to build out from our existing ETAP and Britannia production hubs with low-risk appraisal drilling and development opportunities identified via our differentiated subsurface work flow. We are an established UKCS operator and have recently sanctioned the development of the Finlaggan Field via the Britannia infrastructure where development drilling is underway, all construction contracts have been placed and debt funding secured.

The Zennor team

From a largely shared heritage at ARCO through the 1990s, the management team has subsequently brought success to several North Sea oil companies. This team has now been enhanced by experienced talent brought in from other successful North Sea operators.

  • Our Funding

    Kerogen Capital, Zennor's majority shareholder, increased it's commitment in Zennor to US$300 million in 2016. Kerogen, together with its limited partners, may commit up to a total of US$400 million to Zennor during the course of its investment. Proceeds from Kerogen’s investment are being used to fund the development of Zennor’s existing assets and expand the portfolio by way of new acquisitions, farm-ins and Licensing Rounds.

  • Our History

    Zennor’s heritage and focus can be traced back to the mid-1990s and the successful missed pay strategy of ARCO International. It was during this period that the ‘art’ of missed pay ("undeveloped discoveries") recognition was integrated with real science, producing a systematic process that holds the key to repeatability and hence to success. Zennor is the re-creation of the same subsurface principles, updated with new ideas and concepts.

  • Our Governance

    The Board of Zennor Petroleum Limited comprises Dr Alan Parsley (Chairman), Martin Rowe (Managing Director), Rod Crawford (Technical Director), James Henry (Finance Director), Jason Cheng, Philip Jackson and John Daniel (Non-executives).
