This project describes a methodology designed for unconventional reservoir characterization of a field in northeast of Mexico. The target was an Upper Jurassic source rock formation, correlated with the Haynesville shale in USA. The main goals of this project were to estimate for target formation the distribution, abundance and maturity of organic matter as well as the susceptibility for fracking. This was achieved by means of parameters such as TOC, brittleness, natural fracture distribution and orientation, and principal in situ stresses orientation. This required an integrated geoscience analysis workflow comprising mainly: • Unconventional formation evaluation. • Azimuthal seismic analysis. • Geological framework. • 3D TOC and brittleness prediction. • Characterization of fracture and stresses. Formation evaluation allowed a reliable 3D TOC & brittleness prediction for the target with high correlation with well logs and supported by core data analysis. The seismofacies classification shows a remarkable consistency with TOC/brittleness in accordance with the stratigraphic model. The seismic survey was not wide azimuth, however fracture information could be successfully extracted as shown by the correlation with borehole image interpretation.
