Abstract (en)
[origin: WO2018049311A1] Apparatus and methods for drilling and stimulating a subterranean formation. The method may comprise drilling a wellbore comprising a deviated wellbore portion extending through a subterranean formation, forming a plurality of lateral tunnels extending from the deviated wellbore portion through the subterranean formation such that at least a portion of each of the plurality of lateral tunnels extends along a plane of maximum horizontal stress of the subterranean formation, and performing stimulation operations of the subterranean formation via the plurality of lateral tunnels.
