Lithofacies analysis

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.

  1. Learn as much as possible about the regional geology from well and outcrop control.
  2. Describe cores and cuttings from sequences of interest. Besides describing lithology, grain size, and sedimentary structures, also describe pore geometry.
  3. 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.
  4. Integrate calibrated well logs into well log cross sections constructed during well log sequence analysis.
  5. Interpret depositional environments of lithofacies of depositional sequences using log cross sections and seismic sections with seismic facies analyses.
