ENSCO 121 was constructed at the Keppel FELS yard in Singapore and is expected to soon mobilize to Rotterdam, The Netherlands, for final load-out and crew familiarization.

Petrobras charters FPSO for Santos’ Carioca area

Petrobras and partners BG E&P Brasil and Repsol Sinopec Brasil have signed a letter of intent to charter, through Modec Inc and Schahin Petroleo e Gas S.A., a floating production, storage and offloading (FPSO) unit for the production development of the pre-salt layer in the Carioca area, part of the Santos Basin’s block BM-S-9.

The project will provide for the connection of eight wells to the FPSO, four as producing wells and four as injection. The platform will have a daily processing capacity of up to 100,000 bbls of oil and 5 million cu meters of natural gas.

In addition, Petrobras has drilled well 3-RJS-715D in the Santos Basin pre-salt lara area off the Rio de Janeiro coast to a total depth of 21,889 ft (6,672 meters). After drilling 2,952 ft (900 meters) of carbonate rock below the salt layer at a water depth of 6,981 ft (2,128 meters), a 1,017-ft (310-meter) hydrocarbon column was identified. It is the company’s fifth well in the Santos Basin.

Seadrill to acquire high-spec jackup from Prospector

Seadrill has entered into an agreement to acquire the high-specification Prospector 3 jackup from Prospector Offshore. The rig is based on the F&G JU2000E design with water depth capacity of 400 ft and a maximum drilling depth of 35,000 ft. It is scheduled to be delivered from Dalian Shipbuilding Industry Offshore Co in China during Q1 2014.

Seadrill’s West Auriga drillship, capable of operating in up to 12,000 ft of water, has begun development drilling on BP’s Thunder Horse field in the US Gulf.

Seadrill’s West Auriga begins development drilling

Seadrill’s new ultra-deepwater drillship, the West Auriga, recently began development drilling work on BP’s Thunder Horse field in the deepwater Gulf of Mexico (GOM). The sixth-generation drillship has forward and aft top drives, pipe rackers and a driller’s cabin. The rig can operate in up to 12,000 ft (3,657 meters) of water and has been equipped with a simulator that provides a virtual representation of drill floor equipment to facilitate onboard training.

BP also recently resumed development drilling at the Mad Dog field complex. The company added a reconstructed rig onto the Mad Dog oil and gas production platform to replace the original rig that was damaged and left inoperable by Hurricane Ike in 2008.

With both the West Auriga and Mad Dog rigs online, BP has a company record of nine rigs in its fleet. The company anticipates investing, on average, at least $4 billion in the GOM each year for the next decade. The company plans to concentrate future activity and investment in the GOM on growth opportunities around its four major operated production hubs and three non-operated production hubs in the deepwater, as well as on significant exploration and appraisal opportunities in the Paleogene and elsewhere.

Oil, natural gas discovered in Mirawa-1 well in Iraq

In the Kurdistan region of Iraq, Marathon Oil, Total and the Kurdistan regional government have discovered oil in the Mirawa-1 exploration well on the Harir block. The discovery well reached significant oil and gas columns and was drilled to a total depth of approximately 14,000 ft (4,260 meters).

Eni establishes exploration project with Quicksilver

Eni has signed an agreement with Quicksilver Resources to jointly evaluate, explore and develop unconventional reservoirs onshore in the US. Eni will earn a 50% share in the 52,500 acres held by Quicksilver in the Leon Valley area, located in Pecos County, Texas.

The agreement establishes a three-phase program that includes the drilling of up to five exploration wells and the acquisition of a 3D seismic survey, aimed at determining the hydrocarbon potential of the area and the subsequent development plan.

Eni, along with partners Shell, Petronas Carigali and Osaka Gas Australia, have also drilled an appraisal well in the Evans Shoal gas field in the Timor Sea, Australia. The field is located in the NT/P48 exploration permit in the north Bonaparte Basin.

The Evans Shoal North 1 well was drilled in a water depth of 364 ft (111 meters) and reached a target depth of 12,975 ft (3,955 meters).

Statoil finds oil at Snilehorn in Norwegian Sea

Statoil and its partners have made an oil discovery in the Snilehorn prospect in the Norwegian Sea, approximately 9 miles (15 km) northeast of the Njord field.

Exploration well 6407/8-6 and sidetrack 6407/8-6A, drilled by Songa Offshore’s Trym semisubmersible, have proven several oil columns in formations dating from the Jurassic period. The estimated volume of the discovery is in the range of 55 million to 100 million bbls of recoverable oil equivalent.

Platform P-63 begins production in Papa Terra field

Petrobras and Chevron have started production on platform P-63 in the Papa Terra field located in the southern Campos Basin off the Brazilian coast.
