Natural gas demand is seasonal . We use more gas in the winter to heat our homes, than we do in the summer. This is illustrated in the graph on the right. Natural gas is stored in depleted fields , salt caverns , and aquifers . As shown in the table on the left, depleted gas or oil reservoirs are used most often and comprise the majority of storage.
Aquifers are water reservoirs that are conditioned to hold the gas.
The structural integrity and impermeabilty of salt domes make this underground a good choice. The high withdrawal and injection rates are also important characteristics. All rights reserved.
