Geosynthetic Composite Liners for Brine Ponds
serving the NATURAL GAS STORAGE industry
Natural gas is colorless, odorless and a gaseous hydrocarbon that may be stored a number of different ways. It is most commonly held in inventory underground under pressure in three types of facilities. These are: (1) depleted reservoirs in oil and/or gas fields, (2) aquifers, and (3) salt cavern formations. According to the U.S. Federal Energy Regulatory Commission (FERC), depleted oil and gas reservoirs account for 87% of the total storage capacity, aquifers (10%) and the remaining 3% using salt caverns. Depleted oil and gas reservoirs are most common because of their availability and the advantage of using existing infrastructure whereas salt caverns are more expensive to construct due to the increase in capital cost associated with the leaching and mining of the salt.
Specific to the use of salt caverns, the industry uses brine water to control the flow of the natural gas to and from the salt cavern. In order to facilitate the flow of natural gas, the industry extracts or pumps brine water (a mixture of salt and water) into the cavern. The brine water is stored above ground in ponds referred to as as brine ponds. These brine ponds are generally lined with HDPE geosynthetic liners that can be supplied and installed by ESI.
