DOI: 10.1016/j.jsg.2017.02.011
Abstract: Regional natural fracture networks often show variations on a scale below that captured by seismic reflection data. This variability is not considered in most reservoir models, but likely impacts uncertainties in permeability. We quantify this… read more here.
