  • Gas is produced from the Leman Sandstone Formation of Early Permian age. The reservoir section is comprised predominantly of stacked aeolian dune sands possessing excellent poroperm characteristics.

Low structural relief has presented a major challenge to field development, which has utilized extended reach wells to maximize drainage potential
