LONDON (ShareCast) - Cadogan Petroleum has reported an improvement in its well performance at the Borynya 3, but admitted it had encountered problems with brine leakages.

The firm said that following a process involving a light acid wash, flaring and hydrocarbon samples revealed that oil, condensate and gas were present, with no evidence of formation water in the fluids produced.

However, the group revealed that "persistent completion brine leakage from annulus to bottom packer is still preventing sustainable production at this stage", and that well testing will continue in order to properly purge the formation without brine interference in production.

As anticipated, an acid-frac will be planned for next year in order to obtain and support sustainable and commercial production at Borynya 3, the group said.
