The oil quality, originally estimated at 17 degree API, has subsequently been confirmed to be of 21 degree API and further production testing is planned for this well in 2008. Well ERB-B-1X, which is planned to take 35 days to complete, is targeted to penetrate prospective reservoirs in the Nubian Sandstone and is expected to be drilled to a total depth of 8,300 feet. The ERB-B feature lies 5 kilometres north of the ERB-A discovery and has been identified using existing seismic data, including the 3D survey acquired in early 2007, and is targeting reservoirs proven to be productive in the nearby offshore Ras Budran field.
