Enbridge to Build Crude Oil Pipeline in US GoM

Enbridge Inc., announced that it will build, own and operate a crude oil pipeline in the Gulf of Mexico to connect the proposed Heidelberg development, operated by Anadarko Petroleum Corporation, to an existing third-party pipeline system.

The lateral pipeline is expected to be operational by 2016. Construction of the pipeline is subject to finalization of definitive agreements and sanction of the development by Anadarko and its project co-owners.

The Heidelberg lateral will originate in Green Canyon Block 860, approximately 200 miles southwest of New Orleans and in 5300 feet of water. The pipeline will be 20 inches in diameter and approximately 34 miles in length.

“We are pleased to be working with Anadarko and the Heidelberg producers,” said Leon Zupan, President, Gas Pipelines. “The Heidelberg lateral pipeline is an attractive investment opportunity for Enbridge. It also furthers our objective of diversifying our offshore business to include facilities that support the substantial crude oil discoveries in the deepwater of the US Gulf Coast.”

Enbridge’s offshore pipelines transport approximately 40 per cent of the natural gas produced in the deepwater Gulf of Mexico. The company’s offshore assets include interests in 13 natural gas gathering and transmission pipelines and one crude oil pipeline in five major pipeline corridors off the coasts of Louisiana and Mississippi.

Ecopetrol Updates on US GoM Parmer Propect

Ecopetrol S.A., through its affiliate Ecopetrol America Inc., provided the results of the Parmer Prospect, deepwater Gulf of Mexico.

The Parmer prospect #1 is located on Green Canyon 867, at a depth of 18,900 ft (5,760 meters), which allowed for several pressure readings and the collection of several fluid samples from Miocene sands. The data indicate a column of approximately 240 ft (73 meters) of net condensate-rich gas pay, as prospect as one of 40 ft (12 meters) of net oil pay. In the coming months, Ecopetrol and its partners will reprocess 3-D seismic data and determine a comprehensive delimitation and development plan according to these results.

The two Parmer leases (GC 823 and GC 867) are located within the Green Canyon protraction area, at a depth of approximately 4,200 ft (1,280 meters) underwater. Each covers an area of 5,760 acres (23.3 square kilometers) and is located approximately 143 miles (230 km) from Louisiana.

Ecopetrol America has a 30% interest in the Parmer Prospect. Its partners are Stone Energy, and Apache that is the prospect’s operator.

The Parmer discovery is Ecopetrol’s second deepwater discovery in the Gulf of Mexico, one of the regions with the highest oil hydrocarbon potential in the world.

The results are expected to assist in Ecopetrol S.A.’s strategy to attain a production level of 1.0 million clean barrels of oil equivalent a day by 2015, and 1.3 million clean barrels by 2020.

USA: Nexen’s Kakuna Well Fails to Impress

http://d3n6f555sx1wcx.cloudfront.net/wp-content/uploads/2012/05/USA-Kakuna-Well-Fails-to-Impress-2.jpg

Nexen Inc. today reported that drilling operations are complete on the Kakuna sub-salt exploration well on Green Canyon block 504 located approximately 180 miles southwest of New Orleans in deepwater Gulf of Mexico.

The well did not encounter commercial hydrocarbons, and is now in the process of being plugged and abandoned. Kakuna was drilled to a depth of 30,300 feet at a total cost of approximately $120 million, net to Nexen ($80 million after-tax).

Nexen is the operator of Kakuna with 72.5 %, while Statoil owns the remaining 27,5 %. Norway’s oil giant Statoil farmed into the Kakuna prospect in June 2011.

Nexen owns a broad inventory of exploration prospects in the Gulf of Mexico, including the sub-salt Miocene play in the central Gulf of Mexico and the Norphlet play surrounding our Appomattox discoveries.

The company’s 2012 exploration program includes approximately 15 offshore exploration and appraisal wells in the UK North Sea, West Africa and the Gulf of Mexico.

AMEC, the international engineering and project management company, has been awarded a contract from BP Exploration & Production Inc. (BP) to provide Front End Engineering Design services (FEED) for the topsides facilities for the second phase of the Mad Dog field development. The new facility will be of one of the largest floating production systems to be installed in the Gulf of Mexico.

The contract value has not been disclosed.

“This award is the latest in our on-going global engineering and project management services agreement with BP and continues our long-term collaboration with the largest oil producer in the Gulf of Mexico,” said Simon Naylor, President of AMEC’s Natural Resources Americas business. “The contract further strengthens AMEC’s track record in the development of global deepwater facilities, building on current offshore projects in Brazil and Angola.”

The new facility will produce oil and gas from the Phase 2 development area within the existing Mad Dog field in the Green Canyon region of the Gulf of Mexico, about 200 miles (320 kilometres) south of New Orleans, Louisiana.

Deepwater projects are increasingly important in helping to meet rising demand for oil and gas around the world.

Statoil’s operations in North America got another boost when operator Anadarko Petroleum and co-owners Shell and Chevron today, 12 March, announced the beginning of first production from the Caesar Tonga deep-water project in the Gulf of Mexico.

Caesar Tonga, in which Statoil Gulf of Mexico LLC has a 23.55% working interest, began flowing high-quality oil on 7 March.

Production from the project’s first three wells is expected to ramp up to approximately 45,000 barrels of oil equivalent (BOE) per day.

A fourth development well is expected to be drilled and completed later this year as part of the planned phase one development. Caesar Tonga has an estimated resource base of 200 to 400 million BOE.

“Caesar Tonga fits well with our strategy to significantly grow Gulf of Mexico production over the next several years,” says Statoil’s Jason Nye, senior vice president, U.S. Offshore, Development and Production North America.

“And it’s a great example of using existing infrastructure in the deep-water Gulf to achieve cost savings. The project teams worked well together on this.”

Caesar Tonga is developed as a subsea tieback to Anadarko Petroleum’s Constitution spar floating production facility in about 5,000 feet of water in Green Canyon Block 680 as a host.
In 2009, Anadarko began making modifications to the Constitution’s topsides to accommodate production from Caesar Tonga, about 10 miles to the east.

Caesar Tonga also included the first application of steel lazy wave riser technology in the Gulf of Mexico.

Co-owners in the project are:  Anadarko, with 33.75 percent working interest; Shell Offshore Inc., 22.45 percent; and Chevron U.S.A. Inc., 20.25 percent.
