Based on experiences of several integrated studies in naturally fractured reservoirs (NFR´s), this paper shows the success obtained from apply synergism in the dynamic and static conjugation in a complex fractured Mesozoic field producing in the south of Mexico, and its impact in the simulation process, providing the highest possibilities to be successful in the evaluation of different production alternatives.

The methodology contemplate results like those permeability distributions of the well test analysis, petrophysical parameters from the well logs interpretation, validated with fracture models supported in microstructures through a rigorous analysis on core samples. The adequate treatment of seismic data to define both structure and attributes is transcendent. The existence of fractures associated to folds and faults are the source of preferential fluid channels, affecting the petrophysical properties and the flow efficiency of wells, and therefore the fluid flow in porous media. The suitable combination with sedimentary, megascopic and microscopic fracturing studies, make easy to define NFR´s with low productivity or highly fractured with infinite transmissibility, showing a homogeneous behavior.

This work, for the field example shows that the most important producing wells are associated to patchs reefs with high permeability, surrounded in a same area with permeabilities least than 0.01 mD. The existence of fractures associated to normal and strike slip faults and the fold phenomena have influence in its generation and distribution, and impose the best conditions of productivity in wells near to faults. Due to the different scales used in this study to define the fracture model, the preferential directions of flow are consistent with those results of well testing and validated with the numerical simulation.
