 Kansas Geological Survey Open-file Report 2003-32 |
Facies (5) Ooid packstone-grainstone (Reservoir)
#1 Madsen 3383’
Oomoldic packstone, #23 Batman 2472’, plane polarized light, blue epoxy. |
Oomoldic packstone, #2-05 Poland 3315’, crossed polarized light, blue epoxy. |
Typically massive, horizontally bedded or crossbedded and typically interbedded with undifferentiated packstone-grainstone and wackestone-packstone facies. Ooids compose more than 80% of the grains but other coated grains, peloids, and lumps are also present. This facies indicates higher energy deposition in subtidal to pertidal settings. This facies typically has good oomoldic and intercrystalline porosity and variable moderate to high permeability.
