Anadarko: Another Major Discovery Offshore Mozambique

Anadarko Petroleum Corporation today announced the Golfinho exploration well discovered a new, major natural gas accumulation nearly 20 miles (32 kilometers) northwest of its Prosperidade complex within the Offshore Area 1 of the Rovuma Basin.

The Golfinho discovery well encountered more than 193 net feet (59 net meters) of natural gas pay in two high-quality Oligocene fan systems that are age-equivalent to, but geologically distinct from, the previous discoveries in the Prosperidade complex.

“The success of the Golfinho well significantly expands the tremendous resource potential of the Offshore Area 1 in the deep-water Rovuma Basin, with additional opportunities yet to test,” Anadarko Sr. Vice President, Worldwide Exploration, Bob Daniels said. “The Golfinho discovery, which is entirely contained within the Offshore Area 1 block, adds an estimated 7 to 20-plus Tcf (trillion cubic feet) of incremental recoverable resources over a significant areal extent. This new discovery is only 10 miles offshore, providing potential cost advantages for future development options.

“We are very excited about this new discovery and the value these additional resources represent for the people of Mozambique and our partnership. We look forward to continuing an active exploration program in the highly prospective northern and southern portions of the Offshore Area 1, as well as delineating this new discovery.”

The Golfinho exploration well was drilled to a total depth of approximately 14,885 feet (4,537 meters), in water depths of approximately 3,370 feet (1,027 meters). Once operations are complete at Golfinho, the partnership plans to mobilize the Belford Dolphin drillship to drill the Atum-1 exploration well.

Additionally, at the Barquentine-1 well location in the Prosperidade complex, the partnership successfully tested the upper Oligocene zone, which flowed at a facility-constrained rate of approximately 100 million cubic feet of natural gas per day. This is the third successful drill-stem test flowing at this facility-constrained rate.

Anadarko is the operator in the Offshore Area 1 with a 36.5-percent working interest. Co-owners include 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, ep’s 15-percent interest is carried through the exploration phase.


Norway: PSA Conducts Audit of Major Accident Risk in Connection with Light Well Intervention


In December 2011 and January 2012, the Petroleum Safety Authority Norway (PSA) conducted an audit of Statoil Petroleum AS (Statoil) and Island Offshore Subsea AS (Island Offshore). The audit was aimed at management of major accident risk and the barrier management system in connection with light well intervention on Island Constructor.

Each year, more than 500 well interventions are carried out on the Norwegian shelf, and this number is expected to grow.

There is a high level of risk associated with work on live wells (major accident potential) and many interfaces (multiple alliance partners).

A survey of well intervention activities carried out during the period 2003 – 2008 concluded that there was a significant need for well interventions on subsea installations. Verification on one of the facilities that carries out light well intervention was implemented to investigate HSE challenges linked with this type of operation.

Island Offshore Management and Island Offshore Subsea have an alliance with FMC and Aker Well Service for operation of the Island Constructor which carries out light well intervention on subsea wells for Statoil.


* Evaluate the companies’ understanding, knowledge and expertise as relates to major accident risk and managing barriers, on the part of both company management and among the employees.

* Evaluate strategies and principles which are to form the basis for design, use and maintenance of barriers so that the barriers’ function will be safeguarded throughout the entire facility lifetime.

* Verify that performance requirements are established and implemented.

* Develop the PSA’s expertise in following up management’s work to reduce major accident risk, and clarify the need to develop a framework and supervision methods.

* Contribute to the PSA developing its own methods that will form the basis for more effective barrier supervision.


The audit activity uncovered three nonconformities and four improvement items as regards Island Offshore.

The nonconformities related to deficient analysis of defined hazard and accident situations, layout of kill and stimulation lines, and deficient basis for and documentation of maintenance.


DOE Releases Reports on Major Potential of Wave and Tidal Energy Offshore USA


The U.S. Department of Energy (DOE) released two nationwide resource assessments showing that waves and tidal currents off the nation’s coasts could contribute significantly to the United States’ total annual electricity production, further diversify the nation’s energy portfolio, and provide clean, renewable energy to coastal cities and communities.

These new wave and tidal resource assessments, combined with ongoing analyses of the technologies and other resource assessments, show that water power, including conventional hydropower and wave, tidal, and other water power resources, can potentially provide 15% of our nation’s electricity by 2030. The reports represent the most rigorous analysis undertaken to date to accurately define the magnitude and location of America’s ocean energy resources. The information in these resource assessments can help to further develop the country’s significant ocean energy resources, create new industries and new jobs in America, and secure U.S. leadership in an emerging global market.

The United States uses about 4,000 terawatt hours (TWh) of electricity per year. DOE estimates that the maximum theoretical electric generation that could be produced from waves and tidal currents is approximately 1,420 TWh per year, approximately one-third of the nation’s total annual electricity usage. Although not all of the resource potential identified in these assessments can realistically be developed, the results still represent major opportunities for new water power development in the United States, highlighting specific opportunities to expand on the 6% of the nation’s electricity already generated from renewable hydropower resources.

The two reports—”Mapping and Assessment of the United States Ocean Wave Energy Resource” and “Assessment of Energy Production Potential from Tidal Streams in the United States”—calculate the maximum kinetic energy available from waves and tides off U.S. coasts that could be used for future energy production, and which represent largely untapped opportunities for renewable energy development in the United States.

The West Coast, including Alaska and Hawaii, has especially high potential for wave energy development, while significant opportunities for wave energy also exist along the East Coast. Additionally, parts of both the West and East Coasts have strong tides that could be tapped to produce energy.

Earlier this year, DOE announced the availability of its national tidal resource database, which maps the maximum theoretically available energy in the nation’s tidal streams. This database contributed to the “Assessment of Energy Production Potential from Tidal Streams in the United States” report, prepared by Georgia Tech.

The wave energy assessment report, titled “Mapping and Assessment of the United States Ocean Wave Energy Resource,” was prepared by the Electric Power Research Institute (EPRI), with support and data validation from researchers at Virginia Tech and DOE’s National Renewable Energy Laboratory (NREL). The report describes the methods used to produce geospatial data and to map the average annual and monthly significant wave height, wave energy period, mean direction, and wave power density in the coastal United States. NREL incorporated the data into a new marine and hydrokinetic energy section in their U.S. Renewable Resource atlas.

In addition to the wave and tidal resource assessments released , DOE plans to release additional resource assessments for ocean current, ocean thermal gradients, and new hydropower resources in 2012. To support the development of technologies that can tap into these vast water power resources, DOE’s Water Power Program is undertaking a detailed technical and economic assessment of a wide range of water power technologies in order to more accurately predict the opportunities and costs of developing and deploying these innovative technologies. The Program is currently sponsoring over 40 demonstration projects that will advance the commercial readiness of these systems, provide first-of-a-kind, in-water performance data that will validate cost-of-energy predictions, and identify pathways for large cost reductions.

These resource assessments, techno-economic assessments, and technology demonstration projects are critical elements of DOE’s strategy to capture the very real opportunities associated with water power development, and to further define the path to supplying 15% of the nation’s electricity through water power technologies.

DOE’s Office of Energy Efficiency and Renewable Energy invests in clean energy technologies that strengthen the economy, protect the environment, and reduce dependence on foreign oil. DOE’s Water Power Program is paving the way for industry and government to make sound investment and policy decisions about the deployment of renewable water power technologies by quantifying the nation’s theoretically available water power resources.
