Reservoirs in the Lansing-Kansas City limestone result from complex interactions among paleotopography (deposition, concurrent structural deformation), sea level, and diagenesis. Analysis of reservoirs and surface and near-surface analogs has led to developing a "strandline grainstone model" in which relative sea-level stabilized during regressions, resulting in accumulation of multiple grainstone buildups along depositional strike. Resulting stratigraphy in these carbonate units are generally predictable correlating to inferred topographic elevation along the shelf. Primary porosity in these grainstones was modified by early meteoric diagenesis which laterally and vertically compartmentalized these reservoirs. Effective permeability in oolitic grainstone was radically changed through time eventually controlled by early meteoric leaching to form oomolds and interparticle cements. Continued leaching and later burial crushing of the oomoldic fabric led to a patchy permeability within the original oolitic grainstone facies. This model is a valuable predictive tool for 1) locating favorable reservoirs for exploration, and 2) anticipating internal properties of the reservoir for field development.
