Abstract

Transient indirect boundary element methods for poro-thermoelasticity A. Ghassemi & Q. Zhang Department of Geology & Geological Engineering, University of North Dakota, USA Abstract The development of transient indirect boundary element methods for porothermoelasticity is described. The formulation is within the framework of non-isothermal poroelasticity thus, it can be used to solve problems involving coupled thermal and poromechanical processes. The integral equation formulation and the numerical procedures are briefly described and an a p plication is presented. In particular, the fictitious stress model is used to study the stress and pore pressure distributions around a wellbore drilled in hot rock. There is good agreement between the numerical predictions and the analytical results. The numerical methods are useful for determining the conditions for wellbore failure in hydraulic fracturing or drilling operations. 1 Introduction When fluid saturated rocks are heated (cooled), the bulk so
