Rock Mechanics is the theoretical and applied science of the mechanical behavior of rock; it is that branch of
mechanics concerned with the response of rock to the force fields of its physical environment.
Core Laboratories measures the mechanical properties of a rock, such as Young's modulus, Poisson's ratio, compressive
strength, tensile strength and compressibility. All these parameters are directly related to the drilling (wellbore
stability, drilling mud density determination), production (sand control), stimulation (hydraulic fracture) and
stress map of a reservoir. During a rock mechanical test, compressional and shear velocities are also measured
which generate a series of dynamic properties of the rock under the stress.
