Measuring anisotropic stresses: from the lab to the field

Session ID#: 81486

Session Description:
Measuring stress in the subsurface is of prime interest. Its importance spans applications to earthquakes and energy resources extraction. For example, the failure of a wellbore stems from stress concentrations around the bore exceeding the strength of the formation. Earthquake slip occurs when stress overcomes the breaking strength of a fault. This session is a call for recent advances on approaches and techniques that accurately measure the anisotropic stresses in the subsurface. We highly encourage submissions that focus not only on field scale measurements, but also lab scale validations under controlled conditions.
