Figure 16.
Hydrostratigraphic model of the Wolfcamp showing a horizontal well and two hydraulic fractures. We represent each hydraulic fracture stage as a single planar hydraulic fracture. The horizontal layers represent the permeable dolomitized carbonate flow deposits. The strata between these permeable layers correspond to the low-permeability organic-rich siliceous mudstones. Hydraulic fractures intersect both the high- and low-permeability layers; during production, the more permeable layers drain fluids from the mudstones (red arrows) due to cross-facies flow. The green rectangle represents the model domain described in Figure 19. The thickness of permeable flow deposits and the width of hydraulic fractures and well are not to scale.
