Title: Avery Island core aging and storage effects study: Topical report

A 1-year program of rock property measurements was conducted to assess the possible influences of core aging and shipping, handling, and storage conditions on the hydrothermomechanical properties of domal salt. Core samples collected from the Avery Island mine were randomly assigned to one of several age groups within two test series to be shipped/handled/stored under carefully controlled or under conventional, less well-controlled conditions, respectively. Sets of test measurements were made on specimens of each age group within each series and provided an extensive data base on the stress-strain behavior, compressional wave velocity, electrical resistivity, pore fluid permeability, thermal conductivity, moisture content, and petrofabric features of these samples as a function of age and storage/handling conditions. A substantial increase in predeformation permeability with core age was observed that provides one potentially significant indication of an aging effect. In addition, an apparent trend of decreasing moisture content with increasing age was noted for samples stored/handled under conventional conditions. Except for these effects, however, no data trends were observed that indicate the influence of either core age or storage/handling conditions on the measured behavior of domal salt. 18 refs., 8 figs., 1 tab.
