The ARCO operated Deben gas field flowed first gas yesterday, just 14 months after project sanction. The western extension of the Bure reservoir is also ready to flow gas.

Both Deben and Bure West are being produced via one subsea well each, tied into a new minimal facilities platform which has been added to the existing ARCO operated Thames complex located in block 49/28 of the Southern North Sea. From here the field's gas is exported to shore at Bacton. Production from the fields is remotely controlled via ARCO's shore base in Great Yarmouth.

The Deben field holds estimated recoverable reserves of 33 billion cubic feet of gas, which will be produced over a five year period, with peak production set to reach 37 million cubic feet of gas per day. Bure West's estimated recoverable reserves of 31 billion cubic feet of gas will also be produced over five years with a peak production of 40 million cubic feet of gas per day.

The new Thames platform was constructed by Odebrecht Oil & Gas Services, based on their existing Sea Harvester design. Other key contracts included installation by Seaway Heavy Lift, pipe and umbilical lay by Stolt Comex Seaway, subsea trees by Vetco Gray, control systems by FSSL, and protective structures by AMEC Offshore. Development drilling was conducted by Rowan Drilling. The twin development project is expected to cost approximately £49 mm.

ARCO British Limited's Southern Gas Basin Director, Javan Ottoson commented: "This is the second time in under a month that we are celebrating first gas from new Southern North Sea fields. By using an existing platform design and capitalising on our established processing and export infrastructure we have again successfully brought two small gas accumulations on stream quickly and economically. We have also been able to secure a new lease of life for Thames, ensuring that the complex is fulfilling its potential for years to come."
