Integrating Plug to Well-Scale Petrophysics with Detailed Sedimentology to Quantify Fracture, Vug, and Matrix Properties in Carbonate Reservoirs

Kansas Geological Survey
Open-file Report 99-47


Laminated Muddy Algal Boundstone and Stromatolites (Non-reservoir): Brecciated stromatolite facies typically grades upwards to non-brecciated, in-place stromatolites. Locally or near unconformity may contain isolated vugs which can result in high core-scale permeability that are not (representative of scales larger than whole-core.

Laminated Grainy Algal Boundstone and Stromatolites: Current-modified (ripple) lamination occurs locally. Where stromatolites trapped grains, intercrystalline porosity is present and fenestral, keystone vug, and solution enlarged porosity that closely follows laminations may occur. This facies likely represents subtidal to peritidal (where fenestrae are present) environments. This facies is locally oil stained and can exhibit some of the highest matrix permeabilities in the Arbuckle.
