ABSTRACT
A new approach in fractured reservoir characterization that integrates geomechanics, geology, petrophysics and reservoir engineering is proposed and illustrated with an actual oil reservoir. This approach uses a generalized form of the curvature method to derive a model for fracture intensity and orientation for the Young Deep Unit (YDU). A reservoir inverse model was used to convert the fracture properties into effective petrogeological attributes. The inverse model uses simulated annealing and a black oil simulator to estimate fracture directional permeabilities and pore volume, reservoir wettability, and wellbore properties. The conditioned reservoir model that matches oil, gas, and water monthly rates, and reservoir pressure for a 151 month period, was used to construct an infill drilling criterion map to locate the best infill locations in the YDU.
