The determination of a reservoir's mechanical properties is critical to reducing drilling risk and maximizing well and reservoir productivity. Acoustic logging can provide information helpful to determining the mechanical properties of reservoir rock. Mechanical properties include: * Elastic properties (Young's modulus, shear modulus, bulk modulus, and Poisson's ratio) [SeeStress strain relationships in rocks for calculations of these properties] * Inelastic properties (fracture gradient and formation strength) Elasticity is the property of matter that causes it to resist deformation in volume or shape. Hooke's law describes the behavior of elastic materials and states that for small deformations, the resulting strain is proportional to the applied stress. Depending on the mode of the acting geological force and type of geological media the force is acting upon, three types ofdeformation can result as well as three elastic moduli that correspond to each type of deformation.

Many theoretical models have been developed to predict or correlate specific physical properties of porous rock. Most theoretical models are built on simplified physical concepts: what are the properties of an ideal porous media. However, in comparison with real rocks, these models are always oversimplified (they must be, to be solvable). Most of these models are capable of "forward modeling" or predicting rock properties with one or more arbitrary parameters. However, as is typical in earth science, models cannot be inverted from measurements to predict uniquely real rock and pore-fluid properties.
