A group led by RWE Dea reported production test results for recently completed development wells A04 and A05 in Breagh field in the UK North Sea.
Well A05, now completed, was drilled to total depth of 12,810 ft measured depth about 2½ km northeast of the Breagh Alpha platform. The well has been tested at a maximum rate of 21 MMscfd, said field partner Sterling Resources Ltd.
“Following the testing of the A05 well, the A04 well which was drilled, completed, and suspended in February 2013, was tested and produced at a maximum rate of 26 MMscfd,” Sterling said.
The wells are expected to provide a combined initial production capacity of 45 MMscfd under expected production conditions.
Initial gross production at Breagh is expected to be 135 MMscfd with five of the seven planned production wells on stream. The average production rate for the field is now forecast to be 102 MMscfd for the remainder of this year, assuming first gas production in mid-September.
This estimate reflects appropriate field uptime assumptions following production start-up of the wells and the processing plant, and compares with the previous May 21 forecast of 170 MMscfd, which assumed an early August production start.
Total average production during 2014 at Breagh is now estimated to be 112 MMscfd. This compares with the previous forecast average production rate of 146 MMscfd.
“We are pleased to be able to put another two development wells into service with a combined total of 45 MMscfd of production," stated John Rapach, Sterling chief operating officer. “However, the A05 production rate is somewhat lower than expected, as our petrophysical analysis suggests that the well had encountered the best sands yet found across the field. RWE Dea as operator of Breagh is evaluating the data and may recommend remedial actions which could be conducted in early 2014,” Rapach added.
