Abstract:
Carbonate aquifers and carbonate oil reservoirs contain significant volumes of fresh-water storage and hydrocarbon reserves globally, yet their characterization is extremely complicated. Flow simulations were preformed through a permeability field, including matrix, fracture, and fault permeability distributed in a pattern that mimics observations on an exposure of the Cretaceous Edwards Group in Texas. Matches between location and size of vugs on the outcrop and location of areas having high fluxes on the outcrop slice of the simulation grid suggest that vugs observations can help in characterization of matrix-bed permeability and fracture connectivity. Outcrop surveys of vugs revealed a significant correlation between the relative vug area of a bed and its permeability (R2 = 0.99, P < 1E-5). Vug dimensions and whether the vug is intersected by a fracture were found to be good predictors for distinguishing connected from isolated vugs. These findings open new possibilities for improving reservoir characterization using remotely sensed lidar/phato images. Copyright 2007 by the American Geophysical Union.
