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.

Abstract: A technique facilitates hydrocarbon fluid production. A well is formed in a subterranean region by drilling a borehole, e.g. a generally vertical wellbore. At least one tunnel is formed and oriented to extend outwardly from the borehole at least 10 feet into a formation surrounding the borehole. The orientation of the at least one tunnel is selected such that it extends at a desired angle with respect to a direction of horizontal stress in the formation. A fracture stimulation of the at least one tunnel is performed to create a network of fractures. The orientation of the at least one tunnel ensures that the network of fractures extends through a target zone in a hydrocarbon bearing region of the formation.

Abstract: Methods utilizing ultrasonic acoustic logging tools are provided for detecting thin formation layers that present markedly higher compliance than that of the surrounding rock in, for example, a laminated tight hydrocarbon-bearing formation. These layers may be interpreted as presenting potential interfacial and planes of weakness that may have bearing on the extent of a hydraulic fracture propagating across them.

Abstract: A method of performing a fracture operation at a wellsite is disclosed for a wellsite positioned about a subterranean formation having a wellbore therethrough and a fracture network therein. The fracture network includes natural fractures. The method involves generating wellsite parameters of the wellsite comprising seismic measurements, generating smooth fracture parameters of a smooth fracture by solving governing equations based on the wellsite parameters, and generating ledged fracture parameters of a ledged fracture by identifying ledge locations and generating ledged fracture parameters of a ledged fracture at the ledge locations by solving the governing equations based on the wellsite parameters for the ledge locations.
