To keep model size manageable, yet accurately reflect the fine scale vertical and horizontal heterogeneity over the entire Panoma Field in Kansas, the Council Grove was subdivided during the lithofacies, porosity and permeability modeling phase. The Panoma was divided horizontally into seven genetically related stratigraphic units, A1 (Funston) through C (Neva). Each is a cycle that has a nonmarine interval underlain by a marine interval (e.g.: A1SH and A1LM). The seven permeability models will be joined and uspcaled in the later reservoir simulation phase.
Proportional layering method results in layers proportional to mean thickness of the interval being layered. Number of nonmarine interval layers equals the number of feet in the thickness mean. Number of marine interval layers equals mean thickness in feet plus one standard deviation. Marine and nonmarine intervals were carried through each model resulting in 12 “dummy” layers in each.
Cell size for the modeling is 1000 X 1000 feet, resulting in an average of 8.6 million cells per 5,200 square mile model. The largest model has15 million, the C cycle, and the smallest has 5.7 million, the B2 cycle. Approximately 11 million cells are in the model highlighted in this poster, the A1 cycle.
