Africa (Sub-Sahara) Marathon Oil has produced first gas from its Alba B3 compression platform offshore Equatorial Guinea. The startup enables the company to convert approximately 130 million BOE of proved undeveloped reserves, which more than doubles its remaining proved developed reserve base in the country. Marathon holds an operating interest of about 65% in the field, with Noble Energy holding the remaining stake. Aminex said that gas production from the Kiliwani North-1 well in Tanzania has reached 30 MMcf/D (about 5,000 BOE/D). The project's commissioning process is expected to conclude with a well test to determine the optimal production rate, which previous test data suggest will be approximately 30 MMcf/D, the company said. The operator of the Kiliwani North Development License, Aminex holds a 54.575% interest in the well.
Africa (Sub-Sahara) ExxonMobil will drill its first exploratory well offshore Liberia this month, the company announced on 18 October. Liberia has no oil production at present. Solo Oil plans to spud the Ntorya-2 appraisal well in Tanzania next month. The drilling pad is a mile southwest of the 2012 Ntorya-1 discovery well, which was tested at rates of 20.1 MMcf/D of gas and 139 B/D of condensate. An independent report estimated the discovery to hold 153 Bcf of gas in place, of which 70 Bcf is considered a gross best-estimate contingent resource. A gross best estimate of more than 1 Tcf of gas in place has been made for the Ntorya prospect as a whole, in which the company has a 25% interest. Asia Pacific BP has decided to abandon drilling plans in the Great Australian Bight offshore southern Australia, an area in which prospective drilling has long been contested by environmentalists.
Business drivers are many and varied. Success depends on many factors and how they are mitigated. This panel will look at how Operators and Investors have seen these challenges and coped with the fast-changing landscape they operate in. What will the Energy Industry look like? What are the areas that need to evolve?
Africa (Sub-Sahara) An initial drillstem test on the Mzia-2 well in Block 1 flowed at a maximum rate of 57 million ft3 of gas per day, increasing the estimated recoverable resources from the field to 4.5 trillion ft3. This is the first test carried out on a Cretaceous discovery in deepwater offshore Tanzania. BG (60%) is the operator in partnership with Ophir Energy (40%). Asia Pacific Production has begun from the Wei Zhou 6-12 oil field in the Beibu Gulf basin in the north part of the South China Sea. The project has 10 producing wells drilled at an average water depth of 29.2 m. Salamander Energy signed production-sharing contracts for the Northeast Bangkanai and West Bangkanai license areas, onshore central Kalimantan in Indonesia.
Africa (Sub-Sahara) Drilling began in the SL-5-11 block in the deepwater shelf of west Africa. The targeted depth is 4700 m in water depths of more than 2000 m. Lukoil Overseas (49%) is the operator in partnership with Oranto (30%) and PanAtlantic (21%). Asia Pacific Drilling began on an exploration well in Block G4/50 in the Gulf of Thailand. The planned depth is 2350 m targeting Miocene sandstones. The well is estimated to contain mean prospective recoverable resources of 30 million bbl of oil. Salamander Energy is the operator with a 100% interest. Drilling has been completed on the Klalin-14 development well located in the West Papua region of Indonesia. The well encountered 81 ft of total net pay and tested production rates of 9.8 MMscf/D of natural gas and 220 B/D of condensate on a 24/64-in.
Africa (Sub-Sahara) Oil was discovered at the Ekales-1 wildcat well located in northern Kenya. The well has a potential net oil pay in the Auwerwer and Upper Lokone sandstone reservoirs of between 197 ft and 322 ft. Tullow (50%) is the operator in partnership with Africa Oil (50%). Drillstem tests on the Pweza-3 well offshore Tanzania flowed at a maximum rate of 67 MMscf/D of gas. The tests confirmed the excellent properties of the Tertiary-section reservoir. BG Group (60%) is the operator in partnership with Ophir Energy (40%). Asia Pacific China National Offshore Oil Corporation issued a tender to invite foreign firms to bid for oil and gas blocks in the east and south China Sea. Twenty-five offshore blocks will be offered, including 17 in the South China Sea, three in the East China Sea, and five in the Yellow and Bohai seas.
Africa (Sub-Sahara) An 816-mile 2D seismic acquisition program was completed on the Ampasindava block, located in the Majunga deepwater basin offshore northwest Madagascar. The data will provide improved subsurface imaging of the large Sifaka prospect and will potentially mature additional prospects in the Ampasindava block to drill-ready status. Sterling Energy (UK) holds a 30% interest in the Ampasindava production sharing contract, which is operated by ExxonMobil Exploration and Production (Northern Madagascar) (70%). Asia Pacific The Jolly-1 well, located in the Otway basin onshore in South Australia, was spudded in petroleum exploration license (PEL) 495. The primary objective of the well, whose planned total depth is 4000 m, is to assess the unconventional oil and gas potential of shales within the Casterton formation. Beach Energy (70%) operates PEL 495, with partner Cooper Energy (30%).
Africa (Sub-Sahara) Drilling began on the Bamboo-1 well, located around 35 miles offshore Cameroon in the Ntem concession. The Bamboo prospect is a basin floor fan target within an Upper Cretaceous play. The well will be drilled to an estimated depth of 4200 m. Murphy Cameroon (50%) is the operator, with partner Sterling (50%). The Nene Marine 3 exploration well--located in the Marine XII block, which is around 17 km offshore Congo--encountered a wet gas and light oil accumulation in a presalt clastic sequence Eni (65%) operates the Marine XII block, with partners New Age (25%) and Société Nationale des Pétroles du Congo (10%). Asia Pacific China National Petroleum Corporation (CNPC) stated on its website that its subsidiary, PetroChina, discovered gas in the Moxi block of An'yue field, located in the Sichuan basin, China.
Africa (Sub-Sahara) A drillstem test was performed on the Zafarani-2 well--located about 80 km offshore southern Tanzania. Two separate intervals were tested, and the well flowed at a maximum of 66 MMscf/D of gas. Statoil (65%) is the operator, on behalf of Tanzania Petroleum Development Corporation, with partner ExxonMobil Exploration and Production Tanzania (35%). The FA-1 well--located in 600 m of water in the Foum Assaka license area offshore Morocco--was spudded. The well targets Eagle prospect Lower Cretaceous resources. Target depth is 4000 m. Kosmos Energy (29.9%) is the operator, with partners BP (26.4%),
