Abstract
A process for establishing well-to-well flow communication between a plurality of wells penetrating a subsurface formation is provided. A common fracture network is created by initiating a fracture from a first well, and then propagating that fracture from the first well to a second well. When the fracture has reached the second well, fracturing fluid is injected into the second well and thereby further propagates the fracture to a third well, and so on, so that the fracture is successively propagated to all of the wells. Such a fracture can be located adjacent either a lower or an upper boundary of a tilted subsurface formation, as desired. Techniques are also provided for reducing uneven areal distribution of injection fluids which are injected into fractures.
