Reservoir selection matches location, capacity, and deliverability to market demand; gathering, Previous HitprocessingNext Hit, compression, land acquisition, and pipeline connection significantly impact economics.

Geologic considerations include field-wide variations in permeability, porosity, pay thickness. Well deliverability, and the number of wells required to meet targeted field deliverability can be estimated from (k)h or ^phgr(h). Analogous reservoir types can be used to estimate (k)h, ^phgr(h) ranges for particular fields. Capillary pressure Previous HitdataNext Hit define pore size distribution and gas-water threshold pressure. Existing well location and log Previous HitdataNext Hit are essential in mapping subtle stratigraphic relationships. Definitions of field type, trap type, and liquid phases are important to the economics of storage development and operation, since safe high pressure storage is of greatest benefit.

Well construction considerations include location, type (vertical/slant/horizontal), and completion type to maximize drainage and deliverability; casing sizing to eliminate frictional pressure loss; and casing cementing for long-term mechanical integrity.

Deliverability prediction uses well/gathering system nodal pressure Previous HitdataNext Hit. The importance of deliverability maintenance/ enhancement is increasing as markets demand ever greater deliverability. By design, a field allows cycling of an expected volume; loss of potential decreases efficiency.

Inventory verification relies on well pressure and fluid Previous HitdataNext Hit, accurate metering, and estimation of losses or leaks and fuel use.
