METHODS AND DEVICES FOR HYDRAULIC FRACTURING DESIGN AND OPTIMIZATION: A MODIFICATION TO ZIPPER FRAC.

摘要

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.
