Prior to 2011 exploration in Angola's Kwanza Basin had been disappointing with just a few small oil discoveries having been made in Late Cretaceous and Tertiary reservoirs. Explorers focused on the more productive reservoirs of the Lower Congo Basin instead. However more recently the phenomenal success of the Early Cretaceous pre salt reservoirs in Brazil has brought the exploration potential of the Kwanza back into view. The shared geological history of the two basins has led explorers to believe that the pre salt play in the Kwanza Basin could hold giant deposits of oil.While expectations for the play have rested on oil recent discoveries contain considerable volumes of gas. The lack of a gas market and uncertainties around gas commercialisation are key concerns for operators who will continue to focus on exploration and development of liquids.
