EnCore Oil plc declares an oil discovery at the Bowstring East Prospect (also known as ‘Cladhan’) located in Block 210/29a in the UK Northern North Sea.

The 210/29a-4 Bowstring East discovery well was drilled to a total depth of 9,734 feet. Wireline logging confirmed 25 feet of net hydrocarbon pay over a gross interval of over 110 feet. Wireline pressure data and fluid sampling has established the presence of light oil and, significantly, no oil-water contact was observed.

The group has taken the decision not to carry out a well testing programme and will now suspend the well with a view to re-entering and undertaking sidetracking, coring and testing operations at a future date, following integration of the well results into the seismic model. EnCore has a 16.6 per cent. interest in the licence, and Sterling Resources Limited is the operator.

Alan Booth, EnCore Oil’s Chief Executive Officer, commented, “I am absolutely delighted with the success of this well. The well has intersected a light oil column of over 110 feet within an Upper Jurassic stratigraphic trap. Given its stratigraphic nature, there is potential for the hydrocarbon column height to increase both up dip and down dip of the current location.

“The wireline logging programme confirmed the presence of light oil with no oil-water contact and the group has now obtained sufficient oil samples, reservoir pressure and permeability data to conclude that the cost of a winter well testing programme would be better spent on further appraisal of the discovery. As such the group has decided to suspend the well for likely use during any future appraisal or development drilling.”
