HOUSTON, July 7 – BP PLC has let a key contract for development of Devenick gas-condensate field on Blocks 9/29a and 9/24b in the northern UK North Sea.
The company plans two wells linked to a subsea manifold, which will be tied back to Marathon Oil UK Ltd.’s East Brae platform. East Brae, 33.5 km south of Devenick on Block 16/03a, has been on production since 1993.
The Devenick manifold will have two extra slots for potential future production.
Devenick lies in 114 m of water, 187 miles southeast of Fair Isle and 234 km northeast of Aberdeen.
BP expects production to start in the second quarter of 2012 or earlier.
It expects annual average condensate production rates of 3,231 b/d in 2012 and 4,911 b/d in 2013, declining to 94 b/d by 2027. Peak throughput on East Brae will be 6,814 b/d in 2013.
Gas production will average 78 MMscfd in 2012 and 129 MMscfd in 2013, declining to 17 MMscfd by 2027 and peaking at 201 MMscfd in 2013.
BP let a contract to Technip for project management, engineering, fabrication, installation, and commissioning of the 33.5 km pipe-in-pipe production pipeline, with 16-in. carrier pipeline, 3-in. piggyback methanol line, and infield pipelines comprising various flowlines and umbilicals.
Separately, BP awarded Technip a 3-year diving repair and maintenance frame agreement contract covering all the operator’s platforms, subsea fields, and pipelines in the UK North Sea.
