The rig, scheduled to be completed by the end of Q3 2013, is already contracted to ConocoPhillips for a five-year period on the Norwegian Continental Shelf. The harsh-environment rig will be capable of drilling in water depths up to 150 meters.Seadrill also exercised an option to build a new ultra-deepwater drillship at the Samsung Shipyard in South Korea, with delivery scheduled for Q3 2013. The rig has a design similar to the two drillships previously ordered from Samsung and will be able to operate in water depths up to 12,000 ft. It will be outfitted with a seven-ram configuration of the BOP stack and a 165-ton capacity heave-compensated crane.A new tender barge, T17, is also being constructed at the COSCO Nantong Shipyard in China, to be delivered in Q1 2013. Its design is similar to the two tender rigs Seadrill ordered from COSCO in February 2011.In April, Seadrill’s semi-tender rig West Menang was awarded an 18-month contract by Murphy Sabah Oil to operate on the Kikeh Spar deepwater field in Malaysia.Further, through its affiliate Sea Dragon de Mexico, Seadrill settled an agreement with Pemex for the provision of the ultra-deepwater semi West Pegasus, previously named the Seadragon I.

Barents Sea discovery could open new oil province

Statoil and its partners Eni Norway and Petoro have made a significant oil discovery on the Skrugard prospect in the Barents Sea. Statoil has called this a breakthrough discovery and one of the most important finds on the Norwegian Continental Shelf in the past decade.The well was drilled in a water depth of 373 meters using Transocean’s Polar Pioneer rig, built specifically for the Arctic. The Skrugard prospect is located approximately 100 km north of the Snohvit gas field in the Barents Sea. The estimated volume of the discovery is between 150-250 million recoverable bbl of oil equivalent, and Statoil sees opportunities for further upside in the license of up to 250 million bbl, for a potential of 500 million bbl of oil equivalent. The discovery may open “a new oil province,” said Statoil executive VP for exploration Tim Dodson.

Statoil has plans for the drilling of a new prospect in the same license next year and for a possible appraisal drilling at Skrugard.

Large gas find confirmed near Gorgon in Western Australia

Apache Corp and its partners have made a large gas discovery in the Zola-1 discovery well in license WA-290-P offshore Western Australia. The well logged 410 ft of net pay in three Triassic Mungaroo sands over a depth range of 13,450 ft to 15,100 ft below sea level. Logging tools and formation pressure tests confirmed at least two separate natural gas columns.
Zola-1 is located in the Carnarvon Basin 60 miles north-northwest of Onslow, Western Australia, in a water depth of 930 ft. The discovery is on trend with the Gorgon gas field 16 miles to the north and is near both existing and developing gas infrastructure.

A new seismic survey covering the Zola structure is planned for later in 2011.
