Engineers work near an oil rig used in drilling at the Ngamia-1 well on Block 10BB, in the Lokichar basin, which is part of the East African Rift System, in Turkana County April 5, 2012. Kenya has seen a surge of interest for new oil blocks after striking oil last week, Martin Heya, commissioner of petroleum at the ministry of energy, said on Thursday. The east African country is abuzz with news of its first oil discovery in the dry and dusty northwest town where Africa-focused UK firm Tullow Oil Plc has been exploring.
