Repsol Sinopec Resources UK Ltd., Aberdeen, has started gas production from Cayley field, the third and final discovery to be brought on stream during the major redevelopment of the Montrose area in the central North Sea.
Gross incremental production from Cayley, Godwin, and Shaw fields is expected to peak at 40,000 boe/d, extending the life of the Montrose facilities, installed in 1976, to beyond 2030. Production from Shaw field began last month (OGJ Online, May 9, 2017).
The Montrose area redevelopment project incorporates a new bridge-linked production platform connected to the Montrose Alpha platform to provide additional process and plant support facilities.
Godwin field has already been developed via an extended reach well from the Arbroath platform. Cayley and Shaw fields have been developed as subsea tie-backs to the BLP. The project overall is expected to provide up to 100 million boe of additional production, including life extension of legacy fields.
Repsol Sinopec is operator with 58.97% working interest. Marubeni Oil & Gas (UK) Ltd. is the sole partner. Repsol Sinopec is a joint venture of Repsol SA and Addax Petroleum UK Ltd., a wholly owned subsidiary of China Petrochemical Corp.
