Gas Supply ManagerDescription

• GSM generates a sales gas forecast by allocating
  the demand of multiple contracts among several
  pools according to their deliverability. The gas
  supply from each pool is determined by
  deliverability decline.

3
Gas Supply ManagerDescription cont.

• The principal use of the program is to generate a
  multi-pool gas forecast based on each pools
  deliverability and the total gas contract demand
  including demand from direct sales.
• The deliverability of each pool is determined
  using standard deliverability decline analysis.
• Pool pressure is calculated based on the
  cumulative production and the Initial Gas in
  Place.

4
Gas Supply ManagerApplication

• Knowledge of corporate supply and demand is
  critical in managing multiple gas properties.
  The applications are
• Identify gas contract short falls.
• Identify direct sale potential.
• Investigate the impact of infill drilling.
• Generate corporate gas supply and demand
  forecast.
• Determine economic reserves.
