REGIONAL UPDATE AFRICA Z Gas was discovered at the Mbawa-1 exploration well in the L8 license area, the first hydrocarbon discovery offshore Kenya. The well was drilled to a depth of 2553 m and encountered around 52 m of net gas pay in porous Cretaceous sandstones. The well will be drilled to a total depth of 3275 m. Apache (50%) is operator, with Origin Energy (20%), Tullow Oil (15%), and Pancontinental (15%). Z Eni made the first oil discovery in the Offshore Cape Three Points (OCTP) block, located in the Tano Basin about 31 miles offshore Ghana. The Sankofa East-1X well reached a total depth of 11,975 ft in 2,707 ft of water, and encountered 92 ft of gas and condensate and 249 ft of gross oil pay in Cretaceous sandstones. Eni (47.222%), through its subsidiary Eni Ghana Exploration and Production, is operator of the OCTP block, with Vitol Upstream Ghana (37.778%) and state company GNPC (15%). exploration permits—located offshore Northern Territory and Western Australia— as part of the second round of its 2011 Exploration Acreage Release.

The permit holders aim to spend around AUD 277 million exploring these areas during the next 3 years. Under the agreement, GOSH is set to launch exploration of the central region of al-Attarat-Um El-Ghudran, believed to hold the bulk of the country’s estimated 45 billion metric tons of oil-shale reserves. The term of the agreement is 24 months, during which GOSH is allowed to conduct feasibility studies and carry out drilling operations in the 220-km 2 area. Z Exploration drilling has commenced at the East Simrit prospect (Simrit-3 well), located on the Ain Sifni PSC in the Kurdistan region of Iraq. The well is about 6 miles east of the Simrit-2 discovery well and is exploring the eastern extent of the large-scale Simrit anticline. Hunt Oil Middle East (60%) is operator, with Afren (20%) and the Kurdistan Regional Government (20%). Z The Satyr-2 well encountered about 128 ft of net gas pay.
