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.
