Comments on Geologic Parameters
16 Rock Mineralogy:
Brine chemistry in the Gulf Coast basin is relatively well known because of the brine of hydrocarbon production. We have selected a high-quality, formation-specific data set (Macpherson, 1992); other data are available (for example, Kreitler and Richter, 1986; Kreitler and others, 1988).
