Figure 18.
Lithofacies distribution, thickness, and net-to-gross (NG) ratio of the high-permeability (perm) layers in the upper Wolfcamp. (A) Lithofacies distribution and thickness of low-perm deposits (blue line) and high-permeability dolomitized carbonate deposits (orange line) in the Wolfcamp B and Wolfcamp A units. The permeable deposits are the dolomitic calcareous mudstone and dolomitic calcareous sandstone lithofacies (magenta). (B) The NG profile of high-perm deposits to low-perm strata. The NG was calculated using half the thickness of the deposits (h1/2).
