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.
