The Untold Story of the Gibraltar Prospect, Eastern Cordillera Foothills, Colombia: From the Exploration Phase to the State of the Art 3D-Modelling of a Complex Fractured Reservoir

A recent discovery of gas and condensate in highly fractured reservoirs at the northern culmination of the<br>Eastern Cordillera foothills of Colombia was the result of an integrated exploratory effort in a frontier sub Andean<br>basin by Occidental de Colombia, Inc. and its partners, followed by an intensive re-exploratory effort by<br>Ecopetrol S.A. This discovery consists of east verging highly imbricated fault related folds that involve<br>Cretaceous and early Tertiary fracture reservoirs.
