More Information
Summary:Geomechanical rock properties are a specific group of petrophysical parameters, directly measured in rock mechanics laboratories or by specific field tests. They are also more or less strongly correlated to other petrophysical parameters (for example velocities of elastic waves) and therefore an “indirect” derivation from geophysical measurements is the subject of research and application. There are two types of application:(1)general description or classification of the rock material related to its geotechnical behaviour (rock type, degree of fracturing, density, etc.),(2)determination of geomechanical properties (modulus of deformation, strength properties). With respect to the second type, the correlation between static and dynamic moduli and between seismic velocities and strength properties is discussed more in detail.
