A new technical approach called PetroMod 3D-TecLink® has been applied to a study area in the Bolivian Andes to address and understand complex, compressional tectonic structures in a fully integrated petroleum systems modeling framework. Thrusted strata imply the duplication of individual layers, which poses problems during numerical simulation as it results in multiple depth-values for a given layer. In order to address this problem, the model needs to be subdivided into individual “thrust-” or “fault
blocks”, each representing a geometrical unit, without repetitive strata, within the model cube. While this is a common procedure in software packages that are designed to reconstruct and balance tectonic movement through time (both compressional and extensional), in petroleum systems modeling not only the geometrical aspects through time but also physical properties such as compaction, decompaction, pressure, temperature, maturity, petroleum saturations, etc. need to be addressed. The new technique links the structural geological approach with the petroleum systems modeling approach and is used to investigate and improve predictions for petroleum systems in complex tectonic settings.
