ABSTRACT:
A process and apparatus for simultaneous hydraulic fracturing of a hydrocarbonaceous fluid-bearing formation. Fractures are induced in said formation by hydraulically fracturing at least two wellbores simultaneously. While the formation remains pressurized curved fractures propagate from each wellbore forming fracture trajectories contrary to the far-field in-situ stresses. By applying simultaneous hydraulic pressure to both wellbores, at least one curved fracture trajectory will be caused to be transmitted from each wellbore and intersect a natural hydrocarbonaceous fracture contrary to the far-field in-situ stresses.
