Noble’s New Drillship Enters Three-Year Contract in GoM

Noble Corporation announced that the Company has entered into a three-year term drilling contract with Anadarko Petroleum Corporation for the Noble Bob Douglas, one of Noble’s new ultra-deepwater drillships currently under construction at the Hyundai Heavy Industries Co. Ltd. (HHI) shipyard in Ulsan, South Korea. The drillship, which is being constructed on a fixed price basis, is expected to be utilized for operations primarily in the U.S. Gulf of Mexico.

The Noble Bob Douglas is expected to be delivered in the fourth quarter of 2013. The contract is expected to commence thereafter following mobilization to an initial operating location and client acceptance. Revenues to be generated over the three-year term are expected to total approximately $677 million. The contract also provides for an operating cost escalation provision.

The Noble Bob Douglas is one of four ultra-deepwater drillships being constructed for Noble by HHI. All four drillships are based on a Hyundai Gusto P10000 hull design, capable of operations in water depths of up to 12,000 feet and offering a variable deck load of 20,000 metric tons. The Noble Bob Douglas will be delivered fully equipped to operate in up to 10,000 feet of water while offering DP-3 station keeping, two complete six-ram BOP systems, multiple parallel activity features that improve overall well construction efficiencies and accommodations for up to 210 personnel. The rig will also be equipped with a 165-ton heave compensated construction crane to facilitate deployment of subsea production equipment, providing another level of efficiency during field development programs.

With the award of this contract for the Noble Bob Douglas, two of the Company’s four ultra-deepwater drillships under construction at HHI are now under contract. The remaining two uncontracted drillships are scheduled to be delivered from the shipyard in 2014.

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.

Anadarko Petroleum Corporation , as operator, today announced first production at the Caesar/Tonga development in the Green Canyon area of the deepwater Gulf of Mexico.

Production from Caesar/Tonga, with an estimated resource base of 200 to 400 million barrels of oil equivalent (BOE), is expected to ramp up to approximately 45,000 BOE per day from the first three subsea wells. A fourth development well is expected to be drilled and completed later this year, as part of the planned Phase I development.

“We are excited to announce we began producing high-quality oil from the Caesar/Tonga development on March 7, 2012; an outstanding accomplishment by our project team consisting of co-owners, our employees and contractors,” said President and Chief Operating Officer Al Walker. “Our ability to safely achieve cost savings of almost $1 billion by leveraging our existing, operated infrastructure in the deepwater Gulf of Mexico continues to demonstrate the value of our hub-and-spoke approach to exploration and development. Caesar/Tonga is yet another capital-efficient, deepwater project in our Gulf of Mexico portfolio that we have successfully developed. This development and the Gulf of Mexico are an important part of Anadarko’s liquids growth and our domestically produced energy.”

Anadarko’s First Flow Test Offshore Mozambique Successful

image

Anadarko Petroleum Corporation today announced the results of its first flow test offshore Mozambique. The Barquentine-2 well flowed at an equipment-constrained rate of 90 to 100 million cubic feet per day (MMcf/d), with minimal pressure drawdown, providing confidence in well designs that are capable of 100 to 200 MMcf/d.

“The test at Barquentine-2 exhibited exceptional flow characteristics, confirmed the deliverability of this reservoir and indicated a low density of development wells may be sufficient to produce the reservoir,” Anadarko Sr. Vice President, Worldwide Exploration, Bob Daniels said. “Using pre-set gauges in an offset well, we were able to confirm connectivity and reservoir continuity over a distance of more than 3 kilometers. The test also proves the reservoir has very high permeability, meeting the quality specifications for the partnership’s LNG development plans. This is a very encouraging way to start our testing program, which is an important component in the reserve certification process, as we focus on achieving FID (final investment decision) around the end of 2013.”

The Barquentine-2 well is located in water depths of approximately 5,400 feet (1,650 meters) in the Offshore Area 1 of the Rovuma Basin. The drillstem test was conducted by the Deepwater Millennium drillship, which is expected to be mobilized to the Barquentine-1 location for a second flow and interference test in the complex. The 2012 testing program also includes drillstem tests in the Lagosta and Camarao areas to the south of Barquentine.

Anadarko is the operator of the 2.6-million-acre Offshore Area 1 with a 36.5-percent working interest. Co-owners in the area are Mitsui E&P Mozambique Area 1, Limited (20 percent), BPRL Ventures Mozambique B.V. (10 percent), Videocon Mozambique Rovuma 1 Limited (10 percent) and Cove Energy Mozambique Rovuma Offshore, Ltd. (8.5 percent). Empresa Nacional de Hidrocarbonetos, E.P.’s 15-percent interest is carried through the exploration phase.

Anadarko Strikes More Mozambique Gas

image

Anadarko Petroleum Corporation today said that its latest appraisal well offshore Mozambique, Lagosta-3, encountered approximately 577 total net feet (176 meters) of natural gas pay in multiple zones.

The partnership’s successful appraisal drilling continues to confirm and expand the world-class nature of this massive natural gas accumulation offshore Mozambique,” said Bob Daniels, Anadarko Sr. Vice President, Worldwide Exploration. “The Lagosta-3 well encountered high-quality sands and successfully confirmed an area of the field that was not as well-imaged in our seismic data due to overlying faulting. Additionally, we continue to accelerate our operational learning curve, safely drilling the last two wells faster and more cost effectively than the preceding wells. We expect these drilling-efficiency improvements to translate into significant cost savings over time, as we continue to advance the project.”

The Lagosta-3 well is located about 2 miles (3 kilometers) west of the Lagosta-1 discovery well and 9 miles (15 kilometers) south of the Camarao-1 well. It was drilled to a total depth of approximately 13,715 feet (4,180 meters) in water depths of approximately 4,606 feet (1,404 meters) and will be suspended while the rig is mobilized to drill the Barquentine-4 appraisal well. Anadarko has two deepwater drillships operating in the discovery area offshore Mozambique, the second of which is now on location at the Barquentine-2 well preparing for drillstem testing.

Anadarko and its partners are now advancing a commercial liquefied natural gas (LNG) development in Mozambique that is initially expected to consist of at least two 5-million-tonne-per-annum liquefaction trains.

Anadarko is the operator of the 2.6-million-acre Offshore Area 1 with a 36.5-percent working interest. Co-owners in the area are Mitsui E&P Mozambique Area 1, Limited (20 percent), BPRL Ventures Mozambique B.V. (10 percent), Videocon Mozambique Rovuma 1 Limited (10 percent) and Cove Energy Mozambique Rovuma Offshore, Ltd. (8.5 percent). Empresa Nacional de Hidrocarbonetos, E.P.’s 15-percent interest is carried through the exploration phase.
