ABSTRACT

ABSTRACT: Thermal strain relaxation tests were carried out on core samples from southwestern Ontario and from the Paris Basin to assess the feasibility of the method in orienting horizontal stresses. The strain response for both sets of core was anisotropic and repeatable. Maximum horizontal stress orientations obtained for the Paris Basin core was NE-SW, corresponding to measurements using the differential strain curve analysis and anelastic strain recovery techniques. The value obtained for southwestern Ontario was ESE-WNW. The results from both areas are orthogonal to the known directions. This is discussed in the light of the influence of in-situ microcracks on core-based stress orientation techniques.
