In this paper, we show the case history for the characterization of the naturally-fractured light oil reservoir, Sinan, which is located in the Gulf of Mexico continental shelf, at 40 km north of Frontera port, state of Tabasco, Mexico. Historic production test data from preciously drilled wells showed tremendous well productivity variation as function of well location, and trajectory design. We built a complex 3D structural framework with the use of static and dynamic information. Up-to-date well drilling data was used to continuously calibrate the model as well as 33 km 2 processed seismic information. The resulted framework was derived from the integration of two seismic cubes (time and depth post-migrated), resistive image logs, sonic logs, dipolar logs, core information (petrophysical data), well testing, and geological information. This model provides a quantitative framework for the spatial distribution of subsurface properties of the Sinan Field. As a result of the applied methodology, drilling trajectory and target of proposed development wells were reconsidered. Recommended proposals as a result of this study allow better reservoir fluid contribution which increase and optimize production. The resulted model will be continuously updated to support the drilling of approximately 5 wells per year to fulfill field development requirements.
