L41007 The Effects of Storing Odorized Gas in Gas Storage Reservoir Rocks

In an extensive series of experiments, odorized methane was flowed through sandstone and dolomite cores in the dry, water wet, and oil saturated states to determine the effects that odorants may have on storage reservoir rocks. The purpose of this research was to determine the effects of storing odorized natural gas in gas storage reservoir rocks. The investigation was tailored primarily to observe odorant adsorption and permeability changes in cores resulting from the flow of odorized methane through them. Three different odorant types were used to odorize chemically pure (C.P.) grade methane near and above the odor levels recommended by the manufacturer. Sandstone and dolomite cores were tested in the dry, water wet, and oil saturated states.
