Although containing twice as many grid cells, the new model ran up to four times faster than the previous model by making use of the Analytical Aquifer option within the model, improved relative permeability curves and other model refinements. This paper traces the history of the field...

The facies lateral variations have confirmed the nonuniform depletion throughout this sector of the field, which has led to its zonation. Once the reservoir characterization was complete...

...-classifying the well log responses into several distinct clusters or electrofacies and finding the optimum permeability correlation model for each cluster, improved permeability estimates may be obtained, particularly in heterogeneous carbonate reservoirs. Following conclusions can be drawn based...

... is approximately 250 feet, and average porosity is 10%. The permeability contrast in the reservoir is high, since vugs and fractures lie adjacent to much tighter matrix rock with average permeability of 3.0 md.
