The Satyr-3 well encountered approximately 243 feet (74 meters) of net gas pay. The well is located 113 miles (182 kilometers) north of Exmouth in the WA-374-P permit area, and was drilled in 3,688 feet (1,124 meters) of water to a depth of 13,369 feet (4,075 meters).
George Kirkland, vice chairman, Chevron Corporation, said, “Satyr-3 represents our thirteenth offshore discovery in Australia since mid-2009. This recent discovery reinforces the quality and value of our Australian exploration lease holdings in the Carnarvon Basin.”
Melody Meyer, president, Chevron Asia Pacific Exploration and Production Company, said, “The Satyr-3 discovery adds to our Australian resource base, further supporting our long-term plans to position Chevron as one of the world’s leading LNG suppliers.”

The Azul-1 well, the first to penetrate pre-salt objectives in Angolan deepwater, was drilled in water depths of 923 meters and reached a final depth of 5,334 meters. The condition of the well prevented an assessment of flow capacity by a conventional test. This was performed as a mini-Drill Stem Test that enabled the recovery of two good quality oil samples.
The preliminary interpretation of the data indicated a potential flow capacity greater than 3,000 barrels of oil a day. Taking into account these encouraging results, Maersk Oil will further evaluate the results of this discovery and will proceed with exploration work in the block.
Sonangol E.P. is the block Concessionaire. Maersk Oil is operator of Block 23 with a 50% working interest with partners Svenska (30%) and Sonangol P & P (20%).
“We are encouraged by the results of our first pre-salt exploration well in this region, which was also the first ever deep water well targeting pre-salt reservoirs in the Kwanza Basin. The result may be a further step towards our goal of building up a significant business in Angola,” said Lars Nydahl Jorgensen, Head of Exploration at Maersk Oil.
“There is substantial evaluation work ahead of us to determine whether the discovery is enough to invest further to get production going. This will be done by, amongst other things, state of the art reprocessing of seismic data. Fully appraising the discovery will take several years and it is far too early to guess the outcome,” Jorgensen said.

Fairmount Marine was contracted in July by Diamond Offshore, a leading deepwater drilling contractor headquartered in Houston, to tow the semi submersible drilling rig Ocean Yorktown to the Mexican Gulf region. At that moment Fairmount Alpine just finished a special survey in Durban, South Africa.
The tug was instructed to mobilize towards Ro de Janeiro. Upon arrival in Rio de Janeiro Fairmount Alpine assisted the Ocean Yorktown in the field until the rig was ready in each and every aspect to commence the voyage towards Brownsville. Fairmount Alpine successfully towed the Ocean Yorktown over a distance of 5,400 miles in just 34 days with a general average speed of 6.6 knots, including a two day bunker stop.
The tow of the Ocean Yorktown was the fifth operation for Diamond Offshore Drilling performed by Fairmount Marine. In 2010 Fairmount’s super tugs were involved in four operations for Diamond Offshore.
