Optimal petrophysical evaluations of shale plays require advanced logging programs with appropriate core studies. 3D seismic, micro-seismic, DFIT, and frac job analysis provide additional insight into what impacts reservoir performance. A probabilistic evaluation model, tied to extensive core analysis, identifies critical rock properties that will optimize production. Dipole Sonic mechanical properties computations, with frac job response integration, provide quality stress gradient and brittleness estimates. Image logs identify many geologic features and promote high quality depth control of core samples. With this technology added to the tool box, comprehensive analyses are utilized to create a strong development program.
