Drilling Activity Summary


Three stratigraphic wells were completed in the CPO-17 license in Colombia by the Bogota-based Ecopetrol S.A. subsidiary and operator, Hocol Petroleum. The reservoir target of both stratigraphic wells was the Basal sandstones of the Oligocene Carbonera. The #5a EST was drilled to 848 meters and showed oil-impregnated sandstones from 813 to 826 meters. During the operation, a total of 63 meters of core were obtained and petrophysical analysis indicated 11 meters of net oil sandstones with 27% average porosity. The #6-Est was drilled to 804 meters and showed several oil- impregnated sandstone sections for a total of 6.7 meters of net oil sands, according to a petrophysical analysis. The #6-Est is on the eastern flank of the Merlin prospect channel and confirmed lateral oil saturation with good results. Additional stratigraphic wells and an exploration well, #1-Merlin, will be drilled before the end of 2011.
