The exploration potential for Serrania, Los Picachos, and Macaya contracts are characterized by large, faulted anticlines similar to Capella. Serrania is believed to contain one of the largest undrilled 4-way closure structures in northern South America. Cumulatively, management estimates that the contracts contain at least 6 exploratory candidates with over 65 million barrels of net unrisked prospective heavy-oil resources. Canacol aims to utilize its local knowledge acquired at Capella and extensive exploration activity in the area.
