Abstract:
A technique for providing a fluid conduit between a main bore and a substantially non-producing region of a fracture at a horizontal section of the bore. The technique includes forming a micro-tunnel from a location of the bore adjacent the fracture. The micro-tunnel may be directed at the non-producing region with a angled deflector or in a steerable manner. Additionally, the well may be configured with micro-tunneling at the outset or retrofitted with micro-tunnels as a manner of restoring production.
