Repsol Sinopec delivers first gas from Cayley field, in Montrose Area redevelopment

ABERDEEN -- First gas has been delivered on schedule from Cayley field, the third and final new discovery to be brought on stream during the major redevelopment of the Montrose Area in the Central North Sea operated by Repsol Sinopec Resources UK.

Gross incremental production from Cayley, Godwin and Shaw (brought onstream in May) is expected to peak at 40,000 boepd. This will extend the life of the Montrose facilities, which were installed in 1976, to beyond 2030.

The Montrose Area Redevelopment (MAR) is a major capital project that significantly enhances the long term Montrose Area infrastructure. The project incorporates the development of three new fields - Godwin, Cayley and Shaw - and a new bridge-linked production platform (BLP) connected to the Montrose Alpha to provide additional process and plant support facilities.

The Godwin field has already been developed via an extended reach well from the Arbroath platform. The Cayley and Shaw fields have been developed as subsea tie-backs to the BLP. The project overall is expected to unlock up to 100 MMboe of additional production, including through life extension of legacy fields.

Repsol Sinopec Resources UK Limited is the operator with a working interest of 58.97%, and Marubeni Oil & Gas (UK) Limited is the sole partner.
