Studies of wellhead production capability differ widely in their implications, but much of this is related to the definitional confusion. 'Productive capacity' refers to the maximum rates that wells can flow without regard to downstream constraints in gathering systems, processing plants and pipelines. 'Deliverability' which yields a smaller number, takes into account these potential downstream limitations on the capability to deliver wellhead gas into the pipeline grid. 'Deliverability' is the relevant measure for observers who are trying to monitor the ability of the system to provide gas to end users without potential breakdown. By such a definition the national system had a deliverability cushion of approximately six percent during the abnormally severe cold spell in December 1989. While this was enough to prevent all but isolated breakdowns not all of it was available where it might have been needed because of its location relative to peak market demands. It is important to monitor changes in deliverability as it is affected by the normal decline curve and by additional well drilling. It is also important to track the contribution to deliverability that is made by storage withdrawals, supplementary peaking supplies, and imports.
