A field test of the strain recovery method of stress determination in Devonian shale
The strain recovery approach to in situ stress determination was applied to transversely isotropic Devonian shale core obtained from Meigs County, Ohio. The temperature-corrected recovery strains showed expansion in all directions for a period of about 30 hours. During this time, the average azimuth of the maximum recovery strain was N70E + or - 2/sup 0/. The calculated magnitudes of the maximum and minimum horizontal compressive stresses were about 1.5 times and .8 times the overburden, respectively. Attempts to measure the stresses by hydraulic fracturing at the same site produced inconclusive results. However, the results of the strain recovery approach at Meigs County appear to be consistent with published results from hydraulic fracturing measurements made in other parts of the Appalachian Basin.
