Figure 16 animation (6.5M)--Belle River Mills 3-D reef presentation, showing permeability voxels 25 md and greater (green), porosity voxels 13% and greater (red), rock types (blues and green), and transparent crestal reef structure surface. View is looking northwest, 30 degrees above horizontal. The best permeability and porosity is located in the upper wackestone (dark blue, lower reef) and lower boundstone (light blue, midreef) rock types. The stromatolite rock type (medium blue, upper reef) generally has poorer quality permeability and porosity. Storage and deliverability capacities of this gas storage reservoir could be optimized using this type of 3-D visualization analysis. Vertical exaggeration is 10x. The deviated well (refer to Figure 5) was removed from this presentation.
