South Korea’s Samsung Heavy Industries on Friday announced that it had received contracts for the construction of two drillships without revealing who the costumer was. Today, Seadrill, a Norwegian/Bermudan offshore drilling contractor confirmed the deal.
The construction of the drillships is scheduled for completion in the second and third quarter 2014. Total project price per drillship is estimated to be under US$600 million, which includes a turnkey contract with the yard, project management, drilling and handling tools, spares, capitalized interest and operations preparations. Seadrill has also a fixed price option to order an additional drillship for delivery in 2014.
The drillships are of the same design as the three previous dual derrick drillships that Seadrill ordered at Samsung late 2010 and early 2011, with increased water depth, technical capabilities and accommodation capacities. These dynamic positioning drillships will have a hook load capability of 1,250 tons and a water depth capacity of up to 12,000 feet targeting operations in areas such as the Gulf of Mexico, Brazil as well as West and East Africa. In addition, these units will be outfitted with seven ram configuration of the Blow out Preventer (BOP) stack and with storing and handling capacity for a second BOP.
Chairman of Seadrill John Fredriksen says:
Our long relationship with Samsung has given us access to a proven rig design and favourable delivery slots. In combination with attractive global yard prices, this has created an opportunity to continue to organically build Seadrill with very compelling economics. Seadrill will have five new ultra-deepwater rigs scheduled for delivery in the period 2013 – 2014 and four existing units coming off current contracts in the same period. There has already been specific discussions regarding chartering of part of this capacity. We believe the open ultra-deepwater exposure position will serve Seadrill well and create a unique exposure to one of the fastest growing and most profitable energy businesses in the world. We also believe that this open exposure can be used to further strengthen our relationship with fast growing and dynamic oil companies. The recent increase in daily rates for drilling rigs will generate excess cash that can be used for a balanced combination of organic growth and a strong long-term dividend distribution. It is likely that Seadrill’s commitment to tender and ultra-deepwater new buildings will be further increased in the weeks to come.

BP announced today the drilling of a successful appraisal well in a previously untested northern segment of the Mad Dog field in the US Gulf of Mexico. The well results confirm a significant resource extension for the Mad Dog Field complex, which includes the existing field, in production since 2005, and appraisal drilling of the Mad Dog South field in 2008 and 2009.
Pending confirmation through future appraisal drilling, the total hydrocarbons initially in place in the Mad Dog field complex are now estimated to be up to four billion barrels of oil equivalent.
The well, drilled by BHP Billiton on behalf of the unit operator BP, is located on Gulf of Mexico Green Canyon block 738 approximately 140 miles (225 kilometres) south of Grand Isle, LA., in about 4,500 feet (1,371 metres) of water. The well encountered about 166 net feet (50 metres) of hydrocarbons in the objective Miocene hydrocarbon-bearing sands and discovered an oil column of more than 300 feet (91 metres).
“With these additional hydrocarbon resources north of the main field, Mad Dog has been firmly established as a giant field in BP’s Gulf of Mexico portfolio, rivalling Thunder Horse in size of resource,” said Bob Dudley, BP group chief executive. “Working with the industry and regulators, we will apply our enhanced standards of safety, reliability and compliance to all of our Gulf activities as we continue to provide important jobs and energy to the nation.”
BP maintains a 60.5 per cent working interest in Mad Dog. BHP Billiton has a 23.9 per cent interest, Chevron Corporation, through its subsidiary Union Oil Company of California, has a 15.6 per cent interest.
Due to the materiality of the Mad Dog South finds in 2009, BP has been advancing development options to increase production from Mad Dog by adding another spar production facility with a production capacity of 120,000–140,000 barrels of oil equivalent per day (boed).
“Coupled with the recent exploration success at the discovery at the Moccasin prospect, located in Keathley Canyon, the Mad Dog result re-emphasizes the exploration and development potential of the Gulf of Mexico and the region’s ability to continue to deliver material projects for BP,” Dudley added.
On Sept. 6, 2011 Chevron Corporation announced the Moccasin discovery in the Lower Tertiary play on Keathley Canyon block 736. BP has a 43.75 per cent working interest in the Moccasin prospect. The prospect is operated by Chevron U.S.A. Inc., also with a 43.75 per cent interest, and the co-owner is Samson Offshore Company with 12.5 per cent interest.
The Mad Dog Field started production in 2005 and utilizes a truss spar platform, equipped with facilities for simultaneous production and drilling operations. The facility is designed to process 80,000 barrels/day of oil and 60,000 standard cubic feet/day of gas.
Oil and gas is transported to existing shelf and onshore interconnections via the Mardi Gras Transportation System.
BP is one of the largest producers of oil and gas in the US Gulf of Mexico with net production of over 250,000 boed. BP is progressing eleven Gulf of Mexico projects: Atlantis Phases 2 and 3, Kaskida, Mars B, Galapagos, Na Kika Phases 3 and 4, Freedom, Mad Dog Phase 2, Mad Dog North and Tiber.
Major BP developments in the deepwater Gulf of Mexico include: Pompano, 1994; Marlin, 2000; Horn Mountain, 2002; Na Kika, 2003; Holstein, 2004; Mad Dog, 2005, Atlantis, 2007, Thunder Horse 2008.
