A continuation of the regional overview of the the Southern Llanos Basin discussed in the first two phases (Southern Llanos Basin Hydrodynamics Overview and Southern Llanos Basin Hydrodynamics Overview II). The primary goal of this study is to understand the role of regional hydrodynamics in the CPO 8 area of the southern Llanos Basin and to determine if hydrodynamics plays a role in trapping oil beyond the observed structural and stratigraphic closures.
