Creep curves and fitting parameters for southeastern New Mexico bedded salt
Existing experimental data for 68 separate creep tests on rock salt from the Salado formation of SE New Mexico have been analyzed. The experimental conditions covered an intermediate temperature range from 22/sup 0/C to 200/sup 0/C, and shear stresses from 1000 psi (7 MPa) to 6000 psi (31 MPa). Most tests exhibited both transient and steady-state creep. Data for individual tests have been fitted both to an exponential transient creep law expected to hold at high temperaures (> 200/sup 0/C) and a logarithmic transient creep law expected to hold at low temperature (< 50/sup 0/C). A few tests also exhibited accelerating creep, and these were fitted with an exponential creep law which included an accelerating term. The exponential and logarithmic fits yielded steady-state creep rates which were in good agreement with each other. Low temperature and low stress tests were fitted much better by the logarithmic creep law. At higher tempertures both logarithmic and exponential creep laws were found to fit equally well. Tabulations of fitting parameters and plots of the experimental data and fitted creep curves are presented for each experiment, for use in further analysis.
