LONDON, Oct. 21 -- Sterling Resources Ltd., Calgary, has tested 10.2 MMscfd of natural gas from two zones in the East Breagh well in the UK southern North Sea. The data suggests that this could become one of the larger discoveries of recent years in the area.

Before the well was shut in due to a pressure buildup, it flowed for 12 hours through a 32/64-in. choke at a flowing wellhead pressure of 1,630 psi.

The lower sand zone was perforated at 7,635-7,746 ft measured depth and tested at up to 1.6 MMscfd. "This is the first time such a lower unit has been tested individually, and in addition to proving gas, it provides additional upside and potential for stimulation in future wells," said EnCore Oil, a partner in the well.

The upper sands were then perforated at 7,490-7,560 ft MD.

"The results of this well suggest that the Breagh field is likely to be a single significant gas accumulation," said Alan Booth, EnCore's chief executive. "Both wells—42/13-3 and 42/13-4—have demonstrated reservoir deliverability from vertical well bores, and the latter well has also demonstrated productivity from a lower reservoir."

The partners will drill another well on the western part of the Breagh structure to see how it would deliver gas from a horizontal well and will then analyze development options, production profiles, and recoverability.

EnCore has a 15% interest in the license, and Sterling Resources has 50%. Other partners are Stratic Energy Corp. 10%, Faroe Petroleum (UK) Ltd. 10%, and RegEnergys Ltd. 15%.
