CONCLUSIONS

• Fuhrman-Mascho San Andres field comprises three
  very different reservoirs.
• Each reservoir has distinctive flow unit
  characteristics.
• Image logs provide high resolution identification
  of rock fabrics and architecture.
• Reservoir quality in the upper San Andres is a
  function of depositional facies and
  accommodation.
• Reservoir quality in the lower San Andres is a
  function of diagenesis at the G4 sequence
  boundary.
• Significant overlooked pay may exist below the
  lSA CS bounday.
