The influence of heat-transfer mechanisms during fracture propagation is determined using a general model combining convection along the fracture with conduction and convection in the reservoir. A series of simplified models is also given, together with their ranges of applicability. The thermal simulator is coupled with a fracture propagation model, the rheology of the fracturing fluid being assumed to be time- and temperature-dependent. Implications of the heat-exchange processes on the proppant transport in the fracture and on the post-stimulation well performance are given.
