ABSTRACT:
A process for creating multi-azimuth fractures by hydraulically fracturing a formation via a single wellbore where a special polymer is used as the fracturing fluid. An induced fracture is formed and a solidifiable gel material is injected into the fracture which is allowed to solidify. Thereafter, hydraulic fracturing with the special polymer is repeated causing the fracture trajectory to form contrary to the far-field in-situ stresses.
