The Role of Moldic Porosity in Paleozoic Kansas Reservoirs and the Association of Original Depositional Facies and Early Diagenesis With Reservoir Properties

Kansas Geological Survey
Open-file Report 2003-32

Facies (10) Chert (Non-reservoir)

#23 Batman 2504.8’

Chert commonly occurs as a replacement of carbonate facies (typically preserving original textures) and, locally, original evaporite minerals. Chert replacement commonly results in tight and impermeable areas. Locally, where only partial replacement occurs, some vuggy and intercrystalline porosity is developed.
