In a statement, Angus Energy revealed that, following analysis, it is extremely unlikely that commercial hydrocarbon flows can be established in the Kimmeridge layer via the BR-X4Z borehole using a conventional approach.
It also noted that stimulation techniques including hydraulic fracturing have been ruled out.
“The company, in its role as operator, has already made clear that it is not a proponent of the use of such unconventional production techniques in the Weald and this position remains unchanged,” Angus said.
Angus added that it continues to evaluate options for the licence, though it has also entered into preliminary talks with a third party regarding a sale of its 65% stake in the asset.
It added: “These negotiations are at a very early stage and there can be no certainty as to the outcome including the terms on which any such sale can be made.In the light of this, the company will be considering whether any impairment will be required in the carrying cost of the Brockham licence.”
Alba holds a 5% interest in the Brockham asset.
