Covers topics needed to calculate dynamic elastic rock properties, such as shear modulus, Poisson’s ratio, Young’s modulus, brittleness, overburden stress, pore pressure, and closure stress from modern well logs. Integration and calibration to static and dynamic lab data, implications for hydraulic fracture design, and log editing are discussed.
