Impact of Poroelasticity and Thermoelasticity on Hydraulic Properties of Natural Fractures

This paper will introduce a new method for determining horizontal stress magnitude with the consideration of near-wellbore pressure and temperature changes due to poroelastic and thermoelastic effects. Based on the interpreted direction and magnitude of in-situ stresses, we will assess how the deformation of natural fractures are affected by the in-situ stresses. As a result of the fracture deformations, how the fluid flow properties of natural fractures are affected by poroelasticity, thermoelasticity and the in-situ stresses. Actual examples will be used to explain the interpretation methods.
