Abstract
Systems and methods are disclosed. The method includes obtaining well data for a fluid-saturated rock and obtaining a poroelastodynamic relationship linking a deformation of the fluid-saturated rock to a poromechanical property of the fluid-saturated rock. The method further includes determining the poromechanical property of the fluid-saturated rock by applying a vector operator to the poroelastodynamic relationship. The method still further includes determining a value of the poromechanical property by substituting the well data into the vector-operated poroelastodynamic relationship.
