As the most efficient technique employed in the stimulations for unconventional oil and gas reservoirs, hydraulic fracturing has been widely applied to all the tight gas sand and shale plays in United States. The hydraulic fracture propagation as well as the fracture network play very important role in the success of the fracturing operations. The initiation and propagation of a hydraulic fracture with nearby existing hydraulic fractures are affected by: poroelastic and thermoelastic phenomena as well as by fracture opening under the combined action of applied pressure and in-situ stress. In recent years, a couple of analytical and numerical studies have been done for analyzing the stress reorientations resulting from mechanical effects and poroelastic effects of pre-existing hydraulic fractures. However, few studies have focused on the sensitivity of pressure and temperature effects on the altered stress regime around an existing fracture.
