A method for modeling a reservoir includes receiving vertical formation data describing geological formations in a vertical direction as a function of vertical depth, receiving near-wellbore horizontal formation data describing the geological formations in a horizontal or deviated direction near a wellbore up to a wellbore instrument range, correlating the vertical formation data with the near-wellbore horizontal formation data to create horizontally adjusted formation data to describe the geological formations in the vertical direction beyond the wellbore instrument range, along the horizontal or deviated direction, receiving hydraulic fracture geometry data that describes actual hydraulic fracture geometry, and limiting a described geometry of the geological formations to the actual hydraulic fracture geometry to provide an accurate estimation of usable reservoir.

A method for modeling a reservoir includes receiving vertical formation data describing geological formations in a vertical direction as a function of vertical depth, receiving near-wellbore horizontal formation data describing the geological formations in a horizontal or deviated direction near a wellbore up to a wellbore instrument range, and correlating the vertical formation data with the near-wellbore horizontal formation data to create horizontally adjusted formation data to describe the geological formations in the vertical direction beyond the wellbore instrument range, along the horizontal or deviated direction.

A procedure that integrates petrophysics and rock typing taken from vertical well measurements, 3D seismic elastic properties and seismic attributes, and geostatistical modeling to build a 3D reservoir model is provided. The 3D reservoir model may be directly incorporated into horizontal fracture model designs. The developed 3D reservoir model for a subsurface volume may be used in a fracture model to optimize fracturing designs and maximize well performance.

Rock physics based method of integrated subsurface reservoir characterization for use in optimized stimulation design of horizontal wells

Methods for determining whether to perform a stimulation treatment on a subterranean zone are disclosed. Process zone stress ('PZS'), indicative of a production potential of the subterranean zone, is determined, and a determination is made as to whether the PZS exceeds a preselected value. A PZS exceeding the preselected value may indicate a poor production potential, and a stimulation treatment of the subterranean zone may be avoided. As a result, a substantial cost saving associated with the avoided stimulation treatment may be realized.
