Petroleum Related Rock Mechanics, 2nd Edition

The following tables are included in this appendix:
Table A.1 Static mechanical properties for some common rock types and materials.
Table A.2 Static mechanical properties for some specific rocks.
Table A.3 Density, elastic moduli and sound velocities for some common materials.
Table A.4 Sound velocities for some common rock types.
Table A.5 Thermal properties for some rocks and materials.
The data are compiled from the sources given in the list below. Elastic moduli are from tests under unconfined or near unconfined (low confining pressure) conditions.
Note: For most rocks, material properties such as elastic moduli, strength parameters and sound velocities vary from rock sample to rock sample, in addition to being dependent on measurement conditions (stress, temperature, saturation). Also, material properties are often anisotropic. We have therefore chosen to indicate expected intervals (Tables A.1 and A.4) for the properties. In Tables A.2, A.3 and A.5, when some specific materials are referred to, the values are taken from a specific experiment and need not be representative for other experiments with the same type of rock.
