UK-based Independent Oil and Gas has started a 3D seismic remapping project over its southern North Sea gas portfolio.
The project is being carried out on a phased basis, with the first results expected by the end of May.
The first phase will cover IOG's core southern North Sea area, including Elgood, Cronx and Blythe Skipper oil license area, followed by the prospective southern North Sea area, including Truman, Harvey and Hambleton.
On the core southern North Sea area, IOG has commissioned Baker Hughes Incorporated’s Reservoir Development Services (RDS) to complete a remapping on 3D seismic data IOG purchased last year.
IOG estimates that its 2P reserves on Cronx and Elgood could be more than doubled by this remapping project. Currently IOG’s 2P reserves in Blythe are 17.2 BCF or 3 MMboe (net share).
The remapping work commissioned by IOG will also provide a better understanding of the gas in the Carboniferous beneath Blythe and the oil in the Hauptdolomit above Blythe, the firm says.
The operator of Blythe remains on track to submit a field development plan application for the proven reserves in the Rotliegendes horizon on Blythe by September 2015.
IOG is considering a similar 3D seismic remapping project with Baker Hughes RDS on Skipper. This will help inform a Skipper appraisal well design.
Similar work will be performed by Baker Hughes RDS on the prospective southern North Sea area including Truman, Harvey and Hambleton.
Mark Routh, CEO and Interim Executive Chairman of IOG said: "We are delighted to progress this essential remapping work with the geophysical experts at Baker Hughes RDS. If successful, and subject to a new CPR and funding, our 2P reserves could be more than doubled.
"The remapping of the Blythe Carboniferous gas is also very exciting. I have experience of gas developments in the Carboniferous. The Kew field which flowed at similar rates (0.4 MMcf/d from a vertical unstimulated well) produced at rates in excess of 40 MMcf/d after a successful horizontal multi-zone fracture stimulated well. We look forward to sharing the results of our technical work in due course and also news of our funding plans."
