Africa (Sub-Sahara) Namibia's Ministry of Mines and Energy approved a 1-year extension to its offshore license covering Block 2714A to Chariot Oil & Gas. The extension will allow for the completion of its analysis of the drilling results of the Kabeljou-1 exploration well. Petrobras (30%) is the operator in partnership with Chariot (25%) and BP (45). Asia Pacific Australia's government awarded 13 new offshore petroleum exploration permits after receiving 23 bids for 15 blocks. A total of USD 172 million will be spent exploring the areas, which are located offshore Western Australia and Tasmania, over the initial 3 years of the permit terms. Awardees include China National Offshore Oil, Royal Dutch Shell, Inpex, and Total. The Basset West-1 well encountered 25 ft of gas pay in Jurassic sandstones on the Browse basin offshore Western Australia. The well was drilled to a total depth of 5240 m.

China National Offshore Oil Corporation is the operator with a 100% interest. The Tayum-1 exploration well encountered approximately 49 vertical ft of net gas pay from multiple sandstone intervals within the Miocene and Pliocene section.
Africa (Sub-Sahara) Oil and gas was discovered at the Nene' Marine exploration prospect located in the Marine XII Block offshore Congo. The prospect is estimated to hold 600 million bbl of oil and 700 Bcf of gas. The well was drilled to a total depth of 3031 m and encountered a pre-saline clastic sequence of Lower Cretaceous age. Eni (65%) is the operator in partnership with New Age (25%) and Societé Nationale des Pétroles du Congo (10%). Gas was discovered at the Mkizi-1 well in Block 1 off Tanzania. The well encountered gas pay in three reservoir intervals within a Tertiary aged stacked channel complex. Total net pay was 108 ft. Ophir (40%) is the operator in partnership with BG Group (60%).
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.
Africa (Sub-Sahara) Gas was discovered at two separate levels in the Mronge-1 well in Block 2 offshore Tanzania. The discovery is estimated at between 2 and 3 Tcf of natural gas in place, bringing Block 2's estimated total in-place volumes up to 17 to 20 Tcf. Statoil (65%) operates the Block 2 license on behalf of Tanzania Petroleum Development Corporation, and partners with ExxonMobil Exploration and Production Tanzania (35%). Oil was discovered at the Agete-1 exploration well on Block 13T in northern Kenya. The well, drilled to a total depth of 1929 m, encountered 330 ft of net oil pay in good-quality sandstone reservoirs. Tullow Oil (50%) is the operator with partner Africa Oil (50%).

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%). Production began on the Liuhua 19-5 gas field in the Pearl River Mouth basin in the South China Sea.
