MODELING THERMAL EFFECTS ON HYDRAULIC FRACTURING

Temperature variations are pervasive phenomena in reservoir stimulatio n. To account for the important thermal influences on the pore-pressur e buildup in the hydraulic-fracturing operations, this paper presents a hydraulic-fracturing model (PKN) capable of delineating the impacts of pore-pressure buildup, energy dissipation, and elastic deformation on the hydraulic-fracture geometry. This improvement over the current poroelastic PKN models may provide useful utilities in simulating hydr aulic-fracturing operations where nonisothermal conditions are manifes t.
