Abstract:
A system for extracting resources from a subsurface formation, comprising:a plurality of well bores, each well bore extending from one of a plurality of surface locations to a target zone, the plurality of surface locations disposed substantially linearly relative to each other; a plurality of articulated well bores extending from a single articulated well bore surface location to the target zone, the articulated well bore surface location offset from the plurality of surface locations, each articulated well bore intersecting at least one of the plurality of well bores at a junction proximate the target zone; a plurality of well bore patterns, each well bore pattern extending from a junction of one of the articulated well bores and one of the plurality of well bores into the target zone; and a pumping unit disposed proximate at least one of the well bore patterns operable to remove resources from the target zone through at least one of the respective plurality of well bores.
