Hydrocarbon exploration and development

Map of Ethiopia highlighting Somali Region



The first exploration in the basin was undertaken by Standard Oil in 1920[2] More recent exploration by Tenneco resulted in the discovery of an estimated 68 million cubic metres (2.4 billion cubic feet) of gas in 1974.[2] Development of the reserves in the basin's Calub and Hilala gas fields is being carried out by the Gazoil Ethiopia Project, a joint-venture partnership between the government of Ethiopia and Texas-based Sicor announced in December 1999.[2] [1]

The basin has been divided into 21 blocks,[4] and exploration rights have been awarded for many of them. Companies with concessions in the basin include Netherlands registered Pexco Exploration, Petronas (Malasia), Lundin East Africa (Sweden), South West Energy (Hong Kong), and Afar Explorer (USA).[3]


Political instability and armed conflict

The Ogaden War between Ethiopia and Somalia took place for the control of the region between 1977 and 1978, with a further clash in 1988. In recent years the armed wing of the Ogaden National Liberation Front have been active, and have stated that they will not allow the resources of the region to be exploited, urging international oil companies not to sign agreements with the Ethiopian government.[5]

On April 24, 2007, members of the ONLF attacked and destroyed an oil exploration facility within the basin near Obala and Abole, killing approximately 65 Ethiopians and 9 Chinese nationals in the Abole raid.[6] The facility was being operated by the Chinese Zhongyuan Petroleum Exploration Bureau, a subsidiary of Sinopec[7], on behalf of Petronas.[8][9]
