In March 2018, the Sate Minister of Mines, Petroleum and Natural Resources Koang Tutlam reported that the recoverable gas reserves in the Calub field, Ogaden Basin had increased from 4.7 Tscfg to 6-8 Tscfg due to the discovery of a âdifferent horizonâ in the field.   Calub-Hilala development project, first gas planned for 2020-2021  Calub is operated together with the Hilala gas field by the China Poly Group-Golden Concord Group (Poly-GCL) which also continues exploring in other areas of the Ogaden Basin. The gas from Calub and Hilala will be transported by a 700 km pipeline (already under construction, expected commissioning in late 2018) to a port complex to be built near the coastal city of Damerjog. The complex will also host an LNG plant in its installations area. The fields host combined estimated in place gas resources of more than 4.7 Tscf (see above) and when operational, the plant will export 3 MMcm of LNG per year to be increased to 6 MMcm in the second year.   In late October 2016, Poly-GCL awarded the construction of the pipeline to China Petroleum Pipeline Bureau (CPP), which is a subsidiary of China National Petroleum Corporation specialized in pipeline engineering and construction. The pipeline had a cost of USD 3 billion, of which USD 2 billion were going to be paid by Djibouti and USD 1 billion by the Ethiopian government. The ministry expects to generate approximately USD 1 billion/year revenue from the gas exportation and intends to use part of the gas for domestic use.  In early November 2017, the newly appointed Minister of Mines, Petroleum and Natural Resources Motuma Mekassa reported that the Calub and Hilala fields will start producing gas in mid-2019.   In early 2018, several sources reported that the fields would start producing in 2020-2021.  Â
