摘要
There is taught herein a method of inducing micro fractures and fracture slip in formations thereby creating new dislocations in pre-existing fractures during hydraulic fracturing operations. An embodiment uses multi-component generated signals from multiple seismic signal generators located on or below the surface; and rotating the generated signals such that their vectors of propagation can be varied and optimized for inducing the micro-seismic and fracture slip events for highest cumulative hydrocarbon extraction considering the mechanical properties and direction of the stresses and pre-existing fractures. Embodiments relate to methods for inducing additional seismic events and fracture slip during hydraulic fracturing, particularly micro-seismic events and fracture slip which improve the short and long term production from the reservoir formation. More specifically, but not by way of limitation, embodiments of the present invention relate to such methods for inducing and optimizing the events in the target reservoir formation.
