Lithofacies are interpreted from well data and seismic facies descriptions. Lithofacies interpretations should be based on all available well and outcrop data and on seismic facies interpretations.
Procedure
Below is a suggested procedure for analyzing lithofacies.
- Learn as much as possible about the regional geology from well and outcrop control.
- Describe cores and cuttings from sequences of interest. Besides describing lithology, grain size, and sedimentary structures, also describe pore geometry.
- Calibrate core and cuttings descriptions to well logs and outcrops. Annotate logs with porosity and permeability data (if available) from potential reservoir and seal intervals.
- Integrate calibrated well logs into well log cross sections constructed during well log sequence analysis.
- Interpret depositional environments of lithofacies of depositional sequences using log cross sections and seismic sections with seismic facies analyses.
