Gas Supply Manager Description 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.
Gas Supply Manager Description 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.
Gas Supply Manager Application 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.
