NAIROBI, Kenya, July 10, 2013 (GLOBE NEWSWIRE) -- ERHC Energy Inc. (OTCBB:ERHE), a publicly traded American company with oil and gas assets in Sub-Saharan Africa, announced today that its wholly owned subsidiary, ERHC Energy Kenya Ltd., has contracted Bell Geospace to acquire an airborne Full Tensor Gravity Gradiometry (FTG) survey of Block 11A in northwestern Kenya. The selection of Bell Geospace follows a competitive bidding process. The FTG survey is an airborne survey that aids significantly in the structural mapping of prospective hydrocarbon basins. Using a converted DC-3 aircraft, Bell Geospace will fly a dense grid of flight lines to measure small changes in gravity caused by changes in density of subsurface rocks. This survey method has been used successfully in Africa and contributed to recent oil discoveries in Uganda and Kenya. "Bell Geospace has impressed us with their expertise and experience, and we are excited to be moving forward with this airborne gravity gradiometry survey, a crucial element of ERHC's oil and gas exploration work program in Kenya," said Dr. Peter Thuo, general manager of ERHC Energy Kenya Limited. "When combined with other existing geologic data, this FTG survey will be used to further assess the geological structure of the area, which helps us to identify potential leads and prospects." Subject to certain contingencies and governmental approvals, the survey is expected to be flown through this summer according to a pre-determined timeline. The information gathered will enable ERHC to focus on the most promising areas for acquisition of 2D seismic data, which is the next step in the work program for the Kenya Block. The combined results of the FTG and seismic work will then determine the nature and location of any drilling in the Block. Block 11A is in the vicinity of blocks operated by one of the most prolific oil and gas explorers in Africa. The proximity and in-trend relationship of the Lotikipi plain – the main surface feature of Block 11A – with those blocks as well as the Abu Gabra Rift basins of southern Sudan, which are established petroleum provinces, suggest a high prospectivity for hydrocarbons.
