Filed:

Feb 6, 2012

Appl. No.:

13/366582

Inventors:

Dylan M. Copeland - Katy TX, US

Assignee:

Halliburton Energy Services, Inc. - Houston TX

International Classification:

G06G 7/57
G06F 17/13

US Classification:

703 2, 703 10

Abstract:

The present disclosure relates to modeling the flow of fracturing fluid in a subterranean formation. Fluid flow within the reservoir media in a subterranean formation is modeled by a reservoir block flow model. Fluid flow within a fracture network in the reservoir is modeled by a fracture network flow model. Fluid flow between the fracture network and the reservoir media is modeled by an interface flow model. Output data are generated based on coupling the fracture network flow model, the reservoir block flow model, and the interface flow model. The output data represent characteristics of fracturing fluid leak-off from the fracture network into the reservoir media.

International Classification:

G01V 1/30
G01V 1/28

Abstract:

The invention comprises a method of imaging a volume of the earth's subsurface. A selected volume of the earth's subsurface is divided into a three-dimensional grid of voxels. Seismic signals representing seismic energy emanating from the earth's subsurface and detected by sensors deployed in proximity to said selected subsurface volume and conducted to a recorder for recording. The recorded signals are transformed into a grid of discrete voxel signals representing energy emanating from voxels included in said three-dimensional grid of voxels in the earth's subsurface. A smooth analytic function is defined in three dimensional space based on the grid of discrete voxel signals; and fracture surfaces are derived from the smooth analytic function.

International Classification:

E21B 41/00
G06F 17/50

Abstract:

In some aspects, a set of governing flow equations can be defined for a one-dimensional flow model representing well system fluid in a fractured subterranean region. A first subset of the governing flow equations can represent flow within a fracture, and a second subset of the governing flow equations can represent flow within a reservoir medium adjacent to the fracture. A reduced set of governing flow equations can be generated by eliminating the second subset from the set of governing flow equations based on fluid coupling between the fracture and the reservoir medium. Well system fluid flow in the fractured subterranean region can be simulated based on the reduced set of governing flow equations.

International Classification:

G06F 17/50

Abstract:

In some aspects, techniques and systems for operating a subterranean region model are described. A global system model represents a subterranean region. A global coefficient matrix of the global system model can be identified. The global system includes preconditioned subsystem models. Each of the subsystem models represents a distinct subsystem within the subterranean region and is associated with a respective governing equation. Eigenvalues of the global coefficient matrix can be shifted by a regularization parameter. Shifting the eigenvalues of the global coefficient matrix generates a shifted global coefficient matrix. A solution to a shifted global system that includes the shifted global coefficient matrix can be obtained. The global system model can be solved based on the solution to the shifted global system.

Abstract:

In some aspects, techniques and systems for simulating well system fluid flow are described. Multiple subsystem models each include fluid flow variables and represent well system fluid dynamics associated with a sub-region in a subterranean region. The subsystem models are connected by one or more junction models. The junction models represent interactions among the subsystem models. For each of the subsystem models, an elimination of internal variables of the subsystem model is performed to express the internal variables in terms of junction variables of the junction models. The junction variables are solved based on the junction models. The internal variables of the subsystem model are solved based on the solved junction variables.
