Reevaluation of Colombia's Llanos basin has identified 10 plays and 94 leads and prospects. Some of the plays are conceptual and unproven, such as dip and fault closures within Paleozoic clastics, hydrodynamic trapping in the Paleozoic, and fractured/weathered granitic basement. But all of these higher risk plays have giant field analogs elsewhere in the world. The state oil concern Ecopetrol during third quarter 1993 set in motion a strategy to increase exploration investment in Colombia, specifically in three areas set aside for licensing: Llanos, Putamayo, and Upper Magdalena. In the first of a series of review articles on the areas set aside for licensing new potential is identified in the Llanos basin for both deeper higher risk but large Paleozoic targets and for smaller, shallower traps involving proven lower risk plays.
