Abstract: The present invention provides a method of hydraulically fracturing a well penetrating an subterranean formation by optimizing the spacing of fractures along a wellbore to form a complex network of hydraulically connected fractures by identifying a deviated wellbore in a subterranean formation; introducing a series of fractures in the deviated wellbore, wherein the series of fractures comprising at least a first fracture, a second fracture, a third fracture and a fourth fracture each separated by a non-uniformed and an increased spacing distance such that the spacing distance from each adjacent fracture in the series of fractures is at an increased distance; and forming one or more complex fractures extending from the series of fractures to form a complex fracture network.

Abstract: The present invention provides a method of optimizing the placement of fractures along deviated wellbores by identifying at least two parallel lateral wellbores in a subterranean formation comprising at least a first wellbore and a second wellbore; introducing a first fracture and a second fracture in the first wellbore; introducing a third fracture in the second wellbore between the first fracture and the second fracture, wherein the third fracture extends to an intermediate area between the first two fractures and alters the stress field in that region; and forming one or more complex fractures extending from the first fracture, the second fracture, the third fracture or a combination thereof to form a complex fracture network.
