Block EA5
Block EA5, "the Rhino Camp Basin" is a 6,040 sq km licence area situated at the northern end of the Albertine Graben in northern Uganda (see Figure 1). Figure 2 represents the license area following the renewal of the license in March 2010. The new license area, after relinquishment agreed with the Government, now amounts to 2941 square kilometres.
The block is still in the early stages of exploration. A regional aeromagnetic survey has identified that Block 5 contains one of five identified sedimentary depocentres (or basins) within the Albertine Graben. This has been confirmed by extensive good quality gravity surveys.
The Rhino Camp Basin can be considered to have good hydrocarbon potential by analogy to the other basins within the Albertine Graben where very substantial volumes of commercial reserves have now been discovered. There is a reasonable probability that reservoir, structure and seal are present within the basin and there is strong evidence from gravity and seismic data to support structural presence. The main exploration risk is considered to be the thermal maturity of source rocks and the volume of oil that can be generated.
A first well completed in 2009 showed strong evidence of the presence of oil but favourable reservoir development was not clearly established.. A second exploration well, named Avivi-1, located 3 kms west of Rhino Camp town was drilled in February 2010. The presence of well developed fluvial sandstone reservoirs was thought to be more likely at that location and Rhino Camp town is also where the strongest oil micro seeps are encountered. The well was drilled to a depth of 764 metres but failed to encounter oil. Plans are being prepared for further seismic and another well. Continued
