  • Controlling net treating pressure in a subterranean region
    Patent number: 9297250
    Abstract: In some aspects, an injection treatment of a subterranean region is controlled based on a target net treating pressure. A measure of fluid pressure acting on a subterranean region during an injection treatment is received. The measure of fluid pressure is compared against a target net treating pressure for fluid acting on the subterranean region during the injection treatment. The target net treating pressure is associated with a target fracture growth orientation. The injection treatment is modified based on a result of the comparison.
    Type: Grant
    Filed: March 14, 2013
    Date of Patent: March 29, 2016
    Assignee: Halliburton Energy Services, Inc.

  • Determining a target net treating pressure for a subterranean region
    Patent number: 9217318
    Abstract: In some aspects, a target net treating pressure for an injection treatment of a subterranean region is determined. Fracture growth orientation in a subterranean region is modeled by a computer system. In the model, the fracture growth is a response to fluid pressure acting on the subterranean region. A target net treating pressure for fluid acting on the subterranean region during an injection treatment of the subterranean region is determined based on the modeled fracture growth orientations.
