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.

Another Success Offshore Mozambique for Anadarko

image

Anadarko​ today announced its seventh well in the discovery area offshore Mozambique successfully appraised previous discoveries at Lagosta and Camarao.

The Lagosta-2 appraisal well, located about 4.4 miles (7 kilometers) north of the Lagosta discovery and 5.3 miles (8.5 kilometers) south of the Camarao well, encountered 777 total net feet (237 meters) of natural gas pay in multiple zones.

“This is the largest pay count of any well in the complex to date, and it seems fitting that our seventh successful well in the discovery area would encounter 777 net feet of pay,” said Bob Daniels, Anadarko Sr. Vice President, Worldwide Exploration.

“These excellent results continue to support our recoverable resource estimates of 15 to 30-plus Tcf (trillion cubic feet) of natural gas in the discovery area on our block, as well as provide additional information that will be incorporated into our models to help determine the optimal subsea development plans for the complex. In addition, a second deepwater drillship, the Deepwater Millennium, has arrived in Mozambique to begin an accelerated testing program that will include installing observation gauges and conducting several drillstem tests, as we remain on track to reach a final investment decision for this project in 2013.”

The Lagosta-2 appraisal well was drilled to a total depth of approximately 14,223 feet (4,335 meters) in water depths of approximately 4,813 feet (1,467 meters) in the Offshore Area 1 of the Rovuma Basin. The partnership plans to preserve the Lagosta-2 well for future utilization during its planned drillstem testing program in the Windjammer, Barquentine and Lagosta complex. Once operations are complete, the Belford Dolphin deepwater drillship will be mobilized to drill the Lagosta-3 appraisal well.

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 Makes Substantial Gas Discovery Offshore Mozambique

image

Anadarko Petroleum Corporation today announced the successful Barquentine-3 appraisal well encountered more than 662 net feet (202 meters) of natural gas pay in two high-quality Oligocene-aged fan systems, significantly expanding the estimated recoverable resource range to 15 to 30+ trillion cubic feet (Tcf) of natural gas, with an estimated 30 to 50+ Tcf of natural gas in place.

Barquentine-3 marks the sixth successful penetration in the complex that includes the Windjammer, Lagosta, Barquentine and Camarao discoveries.

“The positive results of each appraisal well that we have drilled and analyzed have continued to increase our estimate of recoverable resources and natural gas in place on our block, and to add to our confidence that this could be one of the most important natural gas fields discovered in the last 10 years, with significant long-term benefits for Mozambique,” said Anadarko Chairman and CEO Jim Hackett. “In parallel, we’ve continued to advance an expandable LNG (liquefied natural gas) development that will support this world-class field. This is great news for Mozambique, as our ongoing activities will continue to spur meaningful investment in the region, generate significant revenue for the government and offer a multitude of opportunities for the people of Mozambique.”

Anadarko President and Chief Operating Officer, Al Walker, added, “The results of Barquentine-3 indicate that we continue to encounter very thick sands with high-quality rock throughout these massive, connected reservoirs. Recoverable resources of this size and quality are perfectly suited for a large-scale LNG development, which is currently being designed to consist of at least two trains with the flexibility to expand to six trains. We also plan to leverage our experience with Independence Hub by constructing an offshore hub facility that will be tied back to the LNG plant onshore. We are already nearing the completion of the pre-FEED (front-end engineering and design) activity and expect to begin FEED work in the near future. Simultaneously, we have analyzed our two new 3D seismic datasets and are excited to have the rig commitments in place to continue our appraisal work while accelerating our exploration activities, including testing a growing number of high-potential prospects in other areas of the Offshore Area 1.”

Anadarko is in the process of mobilizing the Deepwater Millennium drillship to accelerate its activity in the Offshore Area 1. The company also recently signed a four-year contract extension that will keep the Belford Dolphin drillship working in the basin as part of its ongoing program.

The Barquentine-3 appraisal well was drilled to a total depth of approximately 13,400 feet (4,084 meters) in water depths of approximately 5,170 feet (1,575 meters). The well is located approximately 2.75 miles (4.4 kilometers) southeast of the Barquentine discovery well and approximately 1.8 miles (2.9 kilometers) south of the Barquentine-2 appraisal well. The partnership will preserve Barquentine-3 for use as a monitor well during its upcoming testing program. The drillship will next move to top set the Barquentine-4 appraisal well.

Deepwater Millenium Drillship Not Moving to Brazil. Stays in Ghana

image

An ultra-deepwater rig leased by Anadarko Petroleum Corp is no longer heading to Brazil, according to rig owner Transocean Ltd . A source familiar with the matter said last month that Anadarko was considering the sale of some assets in Brazil, which include some deepwater prospects.

Transocean said on Monday its Deepwater Millennium rig would now remain off Ghana at a rate of $576,000 per day through this month, with the rest of its Anadarko contract through July 2013 now up in the air.

“Subsequent operating location is yet to be determined, and the dayrate under the contract could change depending on the country of future operations,” Transocean said in its latest fleet status report.

The Millennium had been set to move to Brazil in July to work on a daily rate of $561,000, according to Transocean’s July fleet status report.

The Switzerland-based rig contractor also said on Monday its midwater rig, Actinia, would move from Malaysia to India to work for ONGC next May, on a three-year contract with a dayrate of $190,000.

Finally, a previously idle Transocean shallow-water rig, the Harvey H. Ward, will start work next month for Pertamina off Indonesia on a $97,000-per-day deal running to May 2013.

Tullow Strikes Oil at Enyenra Well, Offshore Ghana

image

Tullow Oil plc (Tullow) announces that the Enyenra-3A appraisal well, in the Deepwater Tano licence offshore Ghana, has successfully encountered oil in high quality sandstone reservoirs. Pressure data indicates that the Enyenra-3A well has confirmed an up-dip extension of the Enyenra oil field.

Located 6.5km north of the Owo-1 discovery well and 14km north of Enyenra-2A, the well was drilled to test the up-dip extent of the Enyenra oil field. Results of drilling, wireline logs, samples of reservoir fluids and pressure data show that Enyenra-3A has intersected 17 metres of 35o API net oil. Pressure data confirms a continuous oil column of at least 365 metres and that the oil at Enyenra-3A is in static pressure communication with both the Owo-1 discovery well and the Enyenra-2A appraisal well.

The Deepwater Millennium drillship drilled Enyenra-3A to a total depth of 4,031 metres in water depths of 1,102 metres. On completion of drilling operations, prior to flow testing the Enyenra field in late 2011, pressure gauges will be deployed in Enyenra-2A and Enyenra-3A to determine reservoir connectivity. The drillship will depart the Deepwater Tano block in late October having recently been replaced by the Sedco Energy drillship.

The Sedco Energy will later drill the Enyenra-4A well to further appraise the downdip extent of the field. The well will be located 6.8km south of Enyenra-2A and over 20km downdip from the Enyenra-3A well and a result is expected at the end of the year. The Enyenra-5A well also is then likely to be drilled north of Enyenra-3A to test the ultimate updip extent of the field.

Tullow (49.95%) operates the Deepwater Tano licence and is partnered by Kosmos Energy (18%), Anadarko Petroleum (18%), Sabre Oil & Gas (4.05%) and the Ghana National Petroleum Corporation (GNPC) (10% carried interest).

Elsewhere in West Africa, Tullow now expects to announce the result of the Montserrado-1 well offshore Liberia during October.

Commenting today, Angus McCoss, Exploration Director, said:

“This excellent result demonstrates that we are close to declaring the Enyenra and Tweneboa development commercial. Although the ultimate extent of the fields are yet to be fully determined, confirmation of this up-dip extension and long oil column in Enyenra is very encouraging.”
