Kosmos Energy has made a significant deepwater gas discovery off Senegal. The Guembeul-1 well in the northern part of the St. Louis Offshore Profond license in 8,858 ft of water encountered 331 net ft of gas pay in two excellent-quality reservoirs, the company reported. The results demonstrate reservoir continuity and static pressure communication with the Tortue-1 well, which suggests a single gas accumulation. The mean gross resource estimate for the Greater Tortue complex has risen to 17 Tcf from 14 Tcf as a result of the Guembeul discovery, the company said. Kosmos, the operator, has a 60% interest in the well. Timis (30%) and Petrosen (10%) hold the remaining interest.
In Salah Gas has started production from its Southern fields in Algeria. The project is the latest in a program of developing seven central-Algerian fields, which began in 2004. The Southern fields comprise four dry-gas fields: Gour Mahmoud, In Salah, Garet el Befinat, and Hassi Moumene. Drilling began in 2014 and will continue through 2018 with a total of 26 wells planned. Production is expected shortly to reach 500 MMcf/D and eventually to peak at 868 MMcf/D. In Salah is a joint venture between partners Sonatrach (35%), BP (33.15%), and Statoil (31.85%).
China National Offshore Oil Company (CNOOC) has begun production from two shallow-water oil projects in the Beibu Gulf Basin of the South China Sea. The Weizhou 12-2 project includes the Weizhou 12-2 and Weizhou 12-1 West fields and the north part of the Weizhou 11-2 field. Production from three platforms and 18 wells has reached a designed peak level of 16,000 B/D. The Weizhou 11-4 North project is producing about 500 B/D from one well, but is set to achieve peak production of 8,000 B/D within a year as the remainder of its 15 producing wells, spread over two platforms, come on line. CNOOC is the operator and sole interest holder in both projects.
OGDCL discovered oil and gas at the Nashpa X-5 well in the Karak District of Pakistan. Drilled to a 16,587-ft depth, the well targeted the potential of the Shinawari, Lumshiwal, Samanasuk, and Lokhart formations. A test of the Lokhart formation yielded 1,032 B/D of oil and 780 Mcf/D of gas through a 32/64-in. choke at a wellhead flowing pressure of 600 psi. OGDCL is the operator with a 56.45% stake in the well, with the remaining stakes held by Government Holdings (15%) and Pakistan Petroleum (28.55%).
Woodside Petroleum found gas at the Thalin-1A exploratory well in deepwater Block AD-7 in the Rakhine Basin off Myanmar. The well, in 2,743 ft of water, was drilled to a 9,954-ft total depth and encountered a 210-ft gross gas column. Interpretation of the results indicated 203 ft of net gas pay in the primary target zone. Woodside has a 40% interest in the block and is responsible for deepwater drilling. Daewoo, with a 60% interest, is responsible for all other block-related operations.
Bengal Energy announced that hydraulic stimulation has successfully been completed on wells in the ATP 752 Barta Block in the Cooper Basin of Queensland, Australia. Four stimulated wells placed back on production have achieved an aggregate gross increase of more than 200 B/D of oil. The fifth stimulated well was slated to be tested. The results have exceeded technical and commercial expectations, the company said. Bengal has a 30.36% working interest in the block, which is operated by Santos.
Statoil has made a minor natural gas discovery at the 30/9-28 S wildcat well, near the Oseberg field in the North Sea. The well encountered a gas column of about 65 ft, of which 32 ft were situated in sandstone with good reservoir quality in the Tarbert formation. The well also encountered a 39-ft gas column in the Statfjord group in sandstone with moderate reservoir quality. The discovery is preliminarily estimated to hold between 35 MMcf and 70 MMcf of recoverable oil equivalents and will be considered for development as part of the Oseberg Future Phase 2 project.
BP and Oman Oil Company will expand an exploration and production sharing agreement for the Khazzan natural gas field to include a second development phase, at an estimated cost of USD 16 billion for the entire project. The original 1,042-sq-mile development area will be enlarged by 386.1 sq miles. The project will produce 1.5 Bcf/D of gas, or 40% of Oman’s output. The new development requires final approval of Oman’s government and BP, which is expected next year. The reservoir has tight gas, and extraction will require techniques that include hydraulic fracturing.
Petróleos Mexicanos (Pemex) has received approval from Mexico’s oil regulator, the National Hydrocarbons Commission, to drill two new deepwater wells this year near the maritime border with the United States. The planned wells lie within the Gulf of Mexico’s Perdido Fold Belt, which has been very productive in adjacent US waters. The Vasto-1001 well will be drilled to a 23,717-ft depth and is estimated to hold 203 million BOE of mostly light crude oil. The Nobilis-1 well will be drilled to a 19,619-ft depth and is estimated to hold 161 million BOE of mostly superlight crude oil. The Nobilis well is about 4 miles from the Maximino-1 well, a highly promising Pemex deepwater discovery.
Total has started production from the Vega Pleyade gas and condensate field offshore the Tierra del Fuego region of Argentina. It is the world’s southern-most gas development, the company said. The project consists of a wellhead platform in 164 ft of water, which is tied back to the company-operated Rio Cullen and Cañadon Alfa onshore treatment facilities. Vega Pleyade has a production capacity of 353 MMcf/D of gas (70,000 BOE/D). Total is the operator with a 37.5% interest in the project. Wintershall Energía (37.5%) and Pan American Energy (25%) are the other participants.
