... ground-water flow westward down structural dip. The Rubiales field, a large oil reservoir within the eastern Llanos Basin with no structural closure, is located at the edge of one of these stagnation zones. This oil field hosts heavy oils (12° API) consistent with water washing and biodegradation...

... resulted in the discovery of the Guama gas-condensate field. The main reservoir consists of laminar, low-permeability sands in a relatively thick shale-prone sequence of Early and Middle Miocene age. Sequential application of acoustic and elastic inversion and AVO analysis was used to build an evolving 3D...

Petroleum exploration activity in this basin began with the drilling of the first well in 1944. Since then, two oil giants (Cano Limon and Castilla), three major oil fields (Rubiales, Apiay...
