There are two uses for natural gas in storage facilities: meeting base load requirements and meeting peak load requirements. Base load storage capacity is used to meet seasonal demand increases and is capable of holding enough natural gas to satisfy long term seasonal demand requirements. Typically, the turn-over rate for natural gas in these facilities is a year; natural gas is generally injected during the summer and withdrawn during the winter. These reservoirs are larger, but their delivery rates are relatively low, meaning the natural gas that can be extracted each day is limited. Instead, these facilities provide a prolonged, steady supply of natural gas. Depleted gas reservoirs are the most common type of base load storage facility. Peak load storage facilities are designed to have high-deliverability for short periods of time, meaning natural gas can be withdrawn from storage quickly should the need arise. Peak load facilities are intended to meet sudden, short-term demand increases. These facilities cannot hold as much natural gas as base load facilities; however, they can deliver smaller amounts of gas more quickly, and can also be replenished in a shorter amount of time than base load facilities. Salt caverns are the most common type of peak load storage facility, although aquifers may be used to meet these demands as well.

Australia’s biggest petroleum producer and the world’s largest mining company. Its petroleum unit contributed abut 15% of BHP’s revenue for the 2007 fiscal year. Proven reserves were 1.35 billion barrels of oil equivalent, with “probable reserves” to be developed within a decade from projects in Australia, Algeria and the Gulf of Mexico adding a further 2.24 billion barrels

The pressure used as a standard in determining gas volume. Volumes are measured at operating pressures and then corrected to base pressure volume. Base pressure is normally defined in any gas measurement contract.
