Mt. Simon Formation, Michigan Basin and Ohio Area (12a)
Comments on Geologic Parameters
12a CO2 Solubility Brine: Formation Temperature:
According to Sass and others (1998) and Vugrinovich (personal communication, 2000), temperature measurements of the Mt. Simon are very scarce. Therefore, we have used the generally accepted temperature gradient for the Michigan Basin, 25 °C/km (Cercone, 1984). We also have used one data point obtained from Vugrinovich (personal communication, 2000).
