ABSTRACT:
A method of initiating fractures in preselected zones by precooling the zones of interest. A cooling fluid is either circulated in a wellbore at the selected zone or injected into the selected zone. After cooling, conventional fracturing techniques are used, but fractures are more easily controlled by reduction of required pressures in the cooled zones.
