Paper presented at the ISRM International Symposium on In-Situ Rock Stress, May 10–12, 2016
Paper Number: ISRM-ISRS-2016-037
... in this site seems to be in-between strike slip and normal faulting stress regimes. The ASR measurements and hydraulic fracturing tests were consistent in terms of the maximum horizontal stress orientation. Introduction Determination of in situ stress state at a large depth is a very important measurement...

... to verify this method. The shore-based verification and calibration experiments were carried out on the same three core samples used for the onsite measurements. Calibration experiments consist of two steps: K 0 consolidation using a triaxial compression test system, and then ASR measurement using...

Paper presented at the ISRM International Symposium on In-Situ Rock Stress, August 25–27, 2010
Paper Number: ISRM-ISRS-2010-029
... ABSTRACT: To determine three-dimensional stress orientation, we carried anelastic strain recovery (ASR) measurements out using drill core samples taken from a scientific ocean deep drilling project. The lithology of the core samples is mudstone or siltstone with larger porosities ranged from...
