Chemistry and Mineralogy of Samples from the Bayou Choctaw, Bryan Mound, Sulfur Mines, Weeks Island and West Hackberry Strategic Petroleum Reserve Sites, November 1979 Through August 1982

摘要

Chemical and mineralogical data collected on salt core, brine and related samples from five Strategic Petroleum Reserve (SPR) sites over the last three years are collected here for the purpose of documentation and easy reference. The data include identification of the minerals present in bulk core samples and in the water insoluble fractions of core, chemical analysis and densities of core and brine samples, and chemical analysis and mineral identification of materials produced during cavern leaching and during tests conducted on salt dome samples. Core samples are typically greater than 90% halite with the remainder anhydrite. Water insoluble minerals present during various stages of the leaching process are anhydrite and very small amounts of dolomite, calcite, barite and silicate minerals; and a water insoluble mineral inside Bryan Mound brine lines is vaterite. Brine samples analyzed are typically at or near NaCl saturation and contain variable amounts of Ca exp ++ (0.15 to 2.8 mg/g) and SO sub 42- / (0.41 to 4.1 mg/g). 25 tables. (ERA citation 08:038462)
