HOUSTON, Dec. 2, 2013 (GLOBE NEWSWIRE) -- ERHC Energy Inc. (OTCQB:ERHE), a publicly traded American company with oil and gas assets in Sub-Saharan Africa, today announced that its wholly owned subsidiary, ERHC Energy Chad Ltd., has submitted its completed Environmental Impact Assessment (EIA) of Block BDS 2008 to the government of the Republic of Chad. Once review of the EIA is completed, ERHC can advance to the next step in its oil and gas exploration work program: an aeromagnetic survey of BDS 2008. ERHC has 100 percent of the interest in BDS 2008 in southern Chad, which encompasses 41,800 square km., equal to more than 10 million acres. The Block stretches from Chad's western border with Cameroon to the Eastern border with Central African Republic. Aeromagnetic surveys are a common and cost-effective tool for aiding geological mapping over large regional areas and locating target areas for hydrocarbon exploration. ERHC plans to use the information gathered through the aeromagnetic survey with more detailed 2D seismic acquisition. "With an exploration Block as big and spread out as BDS 2008, it is essential that we use this proven and cost effective method of mapping disturbances in the earth's magnetic field that are caused by magnetic minerals in the upper regions of the earth's crust," said Gertjan van Mechelen, ERHC's exploration manager. "We have identified two main areas of focus. One is north of Esso's Tega and Maku discoveries in the Doseo basin and the other is east of and on trend with OPIC's Benoy-1 margin discovery in the Doba basin. We expect the aeromagnetic survey to help identify the most highly prospective areas." Based on its current understanding of the data, ERHC estimates the resource potential in the two focus areas to be as much as 250 million barrels of oil equivalent (MMBOE).
