Abstract

This paper presents an analysis of the deviation of hydraulic fractures associated with the poroelastic change in the in situ stress field caused by fluid injection and pumping in the reservoir. This mechanism is studied within the confines of a simple model involving one injection and one pumping well, and a hydraulic fracture propagating along the path initially equidistant from the two wells. Analysis of the fracture deviation from its straight-ahead path and determination of the conditions leading to attraction of the fracture by the injection well are both based on a theoretical study of the stress trajectories. Comparison of the analytical prediction of the fracture path with the computed path using a numerical technique shows excellent agreement between the two methods, provided that a certain dimensionless toughness is small.
