US Patent:

20160194944, Jul 7, 2016

Filed:

Sep 17, 2013

Appl. No.:

14/911984

Inventors:

- Houston TX, US
David B. Allison - Spring TX, US
Ronald G. Dusterhoft - Katy TX, US

Assignee:

HALLIBURTON ENERGY SERVICES, INC. - Houston TX

International Classification:

E21B 43/26
E21B 43/267

Abstract:

The present disclosure relates generally to subterranean operations and, more particularly, to fracturing a subterranean formation. In one embodiment, the present disclosure provides a method comprising: introducing into a wellbore penetrating a portion of a subterranean formation alternating intervals of a particulate-laden fluid comprising a plurality of particulates sized 100 U.S. mesh or smaller, and a treatment fluid comprising a lesser amount of particulates than the particulate-laden fluid; wherein the alternating intervals of the particulate-laden fluid and the treatment fluid are introduced into the wellbore at or above a pressure sufficient to create or enhance one or more fractures in the subterranean formation.

David Blair Allison - Spring TX, US

Assignee:

Halliburton Energy Services, Inc. - Houston TX

International Classification:

E21B 47/06

US Classification:

1662501, 166 53, 166 50

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.

US Classification:

703 10

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.
