|
Base (cushion) Gas |
The volume of gas needed as a permanent inventory to maintain adequate reservoir
pressures and deliverability rates throughout the withdrawal season. All native gas is
included in the base gas volume.
|
Natural Gas |
A gaseous mixture of hydrocarbon compounds,
the primary one being methane.
|
Net Withdrawals |
The amount by which storage withdrawals exceed storage injections.
|
Storage Additions |
Volumes of gas injected or otherwise
added to underground natural gas reservoirs or liquefied natural
gas storage.
|
Storage Withdrawals |
Total volume of gas withdrawn from
underground storage or from liquefied natural gas storage
over a specified amount of time.
|
Underground Storage Injections |
Gas from extraneous sources put into underground storage reservoirs.
|
Underground Gas Storage |
The use of sub-surface
facilities for storing gas that has been transferred from its original
location. The facilities are usually hollowed-out salt
domes, natural geological reservoirs (depleted oil or gas
fields) or water-bearing sands topped by an impermeable cap
rock (aquifer).
|
Underground Storage Withdrawals |
Gas removed from underground
storage reservoirs.
|
Working (top storage) Gas |
The volume of gas in the reservoir that is in addition to the cushion or base gas.
It may or may not be completely withdrawn during any particular withdrawal season.
Conditions permitting, the total working capacity could be used more than once during any season.
