The interpretation and analysis of depositional systems played an important role in the definition of hydrocarbon reservoirs in the Rodador field of the Isthmian Saline Basin in southeastern Mexico. The two major sandstone reservoirs of the middle Miocene-lower Pliocene Encanto Formation, which are referred to as the 17-A and 18 sands, are located at depths ranging from 2873 m to 2995 m and 2877 m to 3031 m, respectively. The thickness of these two sands ranges from 8 m to 28 m (17-A) and from 7 m to 48 m (18).
The stratigraphic distribution of the hydrocarbon reservoir units and seal rocks has been established, allowing the identification of new, potential areas for exploitation.
The prograding complex of the Encanto Formation is the most attractive from a petroleum perspective, because it hosts the hydrocarbon-producing Rodador field.
A detailed analysis of sand-top maps in this study was used to estimate the original hydrocarbon volume in place, to rank the potential areas for new exploitation plans in the Rodador field. Calculated hydrocarbon reserves are not included in this paper.
