Problems solved by technology

However, the use of interpolation techniques causes an inefficient use of computer processing resources and may cause or otherwise require incorrect introduction of permeability modifiers to match pressures when no modification of reservoir properties is actually required

Abstract

Systems, computer implemented methods, and program products to determine approximate static well pressures for one or more arbitrary shaped wells (119) by estimating the drainage volume (111) of the one or more wells (119), are provided. The drainage volume (111) of the one or more wells (119), for example, can be estimated from the one or more computed fluid flow flux vectors (107), and the approximate static well pressures for the one or more wells (119) can be subsequently calculated by taking the pore volume average of the dynamic grid block pressures within the drainage volume (111) of the one or more wells (119).; The one or more fluid flow flux vectors (107) can be calculated at each iteration in a numerical reservoir simulator as a part of standard simulator computations, negating a need for additional, extraneous computations to calculate effective drainage volume (111) of the one or more wells (119).

Description

[0001] related application [0002] This application is non-provisional and claims U.S. Provisional Patent Application No. 61 / 176261 entitled "Systems, Computer Implemented Methods, and Computer Readable Program Products To Compute Approximate Well Drainage Pressure For A Reservoir Simulator," filed May 7, 2009 Priority interests of , which are hereby incorporated by reference in their entirety. technical field [0003] In general, the present invention relates to the field of petroleum reservoir simulation history matching. More specifically, the present invention relates to the field of calculating approximate static well pressures for one or more wells of arbitrary shape in homogeneous and heterogeneous reservoirs. Background technique [0004] Reservoir simulators are routinely used in reservoir management by major oil companies, independent oil companies, small oil companies, and oil reservoir management consultants. More specifically, oilfield reservoir simulators ar...
