Method And System For Representing Wells In Modeling A Physical Fluid Reservoir

View page
US Patent:
20120303342, Nov 29, 2012
Filed:
Jul 28, 2012
Appl. No.:
13/560996
Inventors:
RANDY DOYLE HAZLETT - Dallas TX, US
Desarazu Krishna Babu - Spring TX, US
International Classification:
G06F 17/13
US Classification:
703 2
Abstract:
The disclosure is directed to a method of representing fluid flow response to imposed conditions in a physical fluid reservoir through wells. The invention utilizes techniques and formulas of unprecedented accuracy and speed for computer computation of Green's and Neumann functions in finite three-dimensional space for arbitrarily-oriented line sources in anisotropic media. The method includes the modeling of fluid flow in physical fluid reservoirs with an assemblage of linear well segments, characterizing arbitrary well trajectory, operating in unison with flux density coupled to flow rate within the well through a constitutive expression linking pressure distribution and flow. The method further includes generalization to complex fracture sets or fractured wells in modeling fluid flow in a reservoir, coupled use of such computations within a mesh representation of the physical fluid reservoir with isolation of well cell contributions, and extension to modeling of heterogeneous reservoirs and pressure transients.

US Patent:
20100286917, Nov 11, 2010
Filed:
May 7, 2009
Appl. No.:
12/436779
Inventors:
RANDY DOYLE HAZLETT - DALLAS TX, US
DESARAZU KRISHNA BABU - ADDISON TX, US
International Classification:
G01V 1/40
US Classification:
702 12
Abstract:
The disclosure is directed to a method of representing fluid flow response to imposed conditions in a physical fluid reservoir through wells. The invention utilizes techniques and formulas of unprecedented accuracy and speed for computations for a fundamental element in analysis of fluid movement through subterranean reservoirs—the calculation of Green's and Neumann functions in finite three-dimensional space. The method includes modeling of pressure and/or flow rate observables at wells in said reservoir using an easily computable, closed-form Green's or Neumann function for a linear well segment in arbitrary orientation within a three dimensional cell of spatially invariant but anisotropic permeability. The method further includes the modeling of fluid flow in the physical fluid reservoir with an assemblage of linear well segments operating in unison with uniform flux density to represent arbitrary well trajectory. The method further includes modeling reservoir flow through one or more linear well segments of non-uniform flux related by a constitutive expression linking pressure distribution and flow rate within the well. The method further includes generalization through integration of easily computable Green's or Neumann functions to represent fractures or fractured wells in modeling fluid flow in a physical reservoir. The system includes modeling fluid flow through a mesh representation of the physical fluid reservoir containing one or more wells represented by easily computable Green's or Neumann functions. The system further includes modeling of flow in the physical reservoir via a numerical method in which the values of pressure and flux assigned to the mesh are related to observables at the well using aforementioned easily computable Green's or Neumann functions. The system further includes the coupling of well and mesh values within the numerical solution method for well observation or feedback control. The system still further includes the localization of the well model to the properties assigned to only those mesh elements penetrated by the well using boundary integral equation methods. The invention also incorporates the addition of transients in fluid flow towards a steady or pseudo-steady state, and use thereof, in the above constructs.
