Presentation Transcript

  1. PETROGRAPHY OF TRENTON/BLACK RIVER CARBONATE RESERVOIRS, APPALACHIAN BASIN

  2. Enhance field studies and core descriptions: Identification of constituent grains Detailed classification of reservoir rocks Interpretation of depositional environments Diagenesis Timing of significant diagenetic events (i.e., cementation or secondary porosity development relative to the emplacement of hydrocarbons) PETROGRAPHY - PURPOSE

  3. PETROGRAPHY - PURPOSE • Frame of reference for geochemical studies • Dolomitization processes: • Stable isotopes • Fluid inclusions • 87Sr/ 86Sr • Trace elements • Source rock studies
