Petronas may begin exporting gas from Ethiopia in 2015 after a production build-up from its Calub and Hilala gas fields, Bloomberg reported July 2, citing a Mines Ministry official. "After five years, Ethiopia will become a producer of natural gas. Our focus will be on the export sector since the local market will consume little," said Eshetu Chala, a senior economist at the ministry. Annual production rates have yet to be determined. "Drilling is going on, but the output capacity will be determined after an appraisal of reserves," said Chala. In 2007, Petronas paid US$80 million for the rights to develop the fields. The fields are located in the Ogaden basin and may contain as much as 4 tcf of recoverable gas. Petronas also plans to build a gas-treatment plant and gas pipeline to a port in Djibouti for US$1.9 billion, according to the Reporter, an Ethiopian newspaper.
