CenterPoint Energy Waterville Gas Storage Project
by John Heer, PE, Allen Boerboom, and Tyler Froman, CenterPoint Energy
Presentation Overview
CenterPoint Energy operates underground natural gas storage and production facilities near Waterville in southern Minnesota. The facilities are used to store natural gas during the summer and withdraw gas during periods of peak needs in the winter. This is an aquifer storage site. The gas is stored about 800 to 900 feet underground below an anticline formation of non-porous shale. Below the non-porous rock is a natural sandstone aquifer called the Mt Simon. The gas is held in place by the natural pressure of the water in the aquifer.
The storage formation holds seven billion cubic feet of natural gas. Two billion cubic feet of this working gas; this is the gas that can be cycled each year for storage and production.
The production section of the facility has a maximum capacity to output 50,000 MCF/Day, (approximately 50,000,000,000 BTUs of energy per day). The gas is withdrawn from the storage field, compressed, dried, and delivered to the Interstate Pipeline system near Medford, MN.
The storage facility development began in 1966 with the first gas injected in 1968. It has been in continuous service since then.
The Minnesota Department of Natural Resources regulates the storage of gas underground.
