BP makes 15th discovery in ultra-deepwater Angola block
Sonangol and BP have announced the Portia oil discovery in ultra-deepwater Block 31, offshore Angola. Portia is the 15th discovery that BP has drilled in Block 31. The well is approximately 7 km north of the Titania discovery. Portia was drilled in a water depth of 2,012 m, some 386 km northwest of Luanda, and reached 5,678 m TVD below sea level. This is the fourth discovery in Block 31 where the exploration well has been drilled through salt to access the oil-bearing sandstone reservoir beneath. Well test results confirmed the capacity of the reservoir to flow in excess of 5,000 bbl/day.
Pride drillships awarded contracts by BP, Petrobras
Pride International has announced two multi-year contracts for two ultra-deepwater drillships. First, a five-year contract with a BP subsidiary will allow Pride to expand its deepwater drilling operations and geographic reach in deepwater drilling basins to the US Gulf of Mexico. The contract is for a ultra-deepwater drillship under construction at the Samsung shipyard in South Korea. Scheduled for delivery during Q1 2010, the rig will be capable of drilling in water depths up to 12,000 ft (equipped for 10,000 feet) and drilling to a total vertical depth of up to 40,000 ft.
The second contract is with a Petrobras subsidiary, for the construction and operation of an advanced-capability, ultra-deepwater drillship in support of Petrobras’ international exploration and development drilling projects. The rig, to be constructed at the Samsung shipyard, is expected to be delivered in Q1 2011. The contract allows Petrobras to elect, by 31 January 2010, a firm contract term of at least five years and up to seven years.
Separately, Pride has announced contract extensions from Petrobras for deepwater semis Pride Rio de Janeiro and Pride Portland. The extensions, representing six years per rig, are expected to commence during late 2010 to early 2011, in direct continuation of each rig’s current contract commitment and a scheduled shipyard program. The rigs have operated offshore Brazil for Petrobras since entering service in 2004.
Rowan jackup moving to Middle East to drill offshore Saudi Arabia
Rowan Companies’ Bob Keller jackup has been awarded a three-year drilling contract, which includes an option for a fourth year, for work offshore Saudi Arabia. The Bob Keller recently concluded work in the Gulf of Mexico and is en route to the Middle East. It is expected to commence drilling operations during Q2 2008. Rowan re-entered the Middle East market two years ago after a 25-year absence. This contract expands its presence in the area to nine jackups.
Rowan also has announced a multi-well contract with McMoRan Oil & Gas Corp that includes re-entering the Blackbeard Prospect. The Gorilla IV has been committed for a minimum of 90 days, and work on Blackbeard is priced at a dayrate in the mid-$190s. The initial Blackbeard well was drilled to a depth of just over 30,000 ft during 2005-06 by Rowan’s first Tarzan Class jackup, the Scooter Yeargain.
Additionally, Rowan’s Super Gorilla class jackup, the Bob Palmer, is undergoing final preparations for its initial assignment on BP’s Eldorado Prospect. The rig will drill one or more wells targeting a depth of at least 28,000 ft.
StatoilHydro to drill first offshore prospect as operator in Canada
StatoilHydro will drill its first offshore prospect as operator in Canada in Q4 2008, at the Mizzen prospect off the east coast of Newfoundland and Labrador. Husky Energy will participate in the exploration well. A rig-sharing contract with Petro-Canada and Husky will allow StatoilHydro to bring in Transocean’s Henry Goodrich rig for the operation. It is expected to arrive in Newfoundland this summer. The Mizzen prospect is located in block EL 1049 in the Flemish Pass Basin offshore Newfoundland and Labrador in 1,100 m water depth.
