Fluid Flow and Heat Transport Computation for Power-Law Scaling Poroperm Media

Figure 1

Effective porosity distribution in 2 Hm-scale simulation of the MWX crustal volume transected by a vertical wellbore. The colour-bar codes the degree of porosity in the section. Cool colours denote the 3D ambient distribution of spatially correlated porosity in accord with spatial fluctuation power-law spectral scaling (5) for well-log porosity range 0.1 < φ < 0.3. Warm colours denote elevated effective porosity with elevated poroconnectivity parameter α controlling permeability via (7). These layers represent crustal faults that intersect the transecting wellbore at depths recording spikes in neutron porosity well-log.
