Transocean John Shaw Arrives at Timon Prospect (UK)

Transocean John Shaw to Complete Drilling of UK Timon Prospect

MPX North Sea Limited announces that the Transocean John Shaw semi-submersible drilling rig has arrived on location to complete the drilling of the Timon prospect located in the UK Northern North Sea in Blocks 211/11b and 211/16b.

The 211/11b-7 well was originally spudded in May 2012 before being suspended due to operational problems with the drilling rig. Operations are being undertaken by TAQA Bratani on behalf of the P1633 group as part of its multi-well programme with the John Shaw and the well is anticipated to take around 40 days to complete. The partners in the P1633 licence are MPX North Sea Limited (operator, 15%), Agora Oil & Gas (UK) Limited (a wholly owned subsidiary of Cairn Energy PLC) (25%), Taqa Bratani Limited (18%), Wintershall E&P Limited (17%), Sorgenia E&P (UK) Ltd (15%) and Valiant Causeway Limited (10%).

In a different area and after a full review of prospectivity, the Company (and its partners) have decided to relinquish Licence P1793 (Blocks 22/1a and 22/2c) effective 10th January 2013, rather than take on a drilling commitment.
