Paper presented at the SPWLA 56th Annual Logging Symposium, July 18–22, 2015
Paper Number: SPWLA-2015-VVV
... to pin parameters down to improve sand failure prediction, acquiring monopole and dipole sonic in stress sensitive formations together with borehole image prove to be an important piece of information. The integrated stress analysis provides valuable information regarding the field stress state. It also...

Paper presented at the SPWLA 52nd Annual Logging Symposium, May 14–18, 2011
Paper Number: SPWLA-2011-P
.... Resistivity images are fundamentally utilized in this study to measure fracture properties (dip, strike and apparent aperture) and to evaluate the tectonic stress state around the boreholes. Distributions of fractures identified on the resistivity images were correlated with additional log data including...

Paper presented at the SPWLA 43rd Annual Logging Symposium, June 2–5, 2002
Paper Number: SPWLA-2002-EE
.... Based on the breakout analysis and hydraulic fracturing data, the remnant stress state of the Minami-Nagaoka gas field is in strike-slip faulting regime, and the maximum horizontal stress, trending west-northwest to east-southeast, is about 1.6 times larger than the minimum horizontal stress. It means...

Paper presented at the SPWLA 40th Annual Logging Symposium, May 30–June 3, 1999
Paper Number: SPWLA-1999-WW
... that conventional long-spaced sonic tools will not be affected. If specially designed tools are used to log velocities of the damaged zone, the data may be interpreted to yield stress information. Unloaded cores will show a velocity anisotropy that reflects the forming stress state. Cores that have been loaded back...
