Integrated well flow modeling (Paperback)

This book summarizes the innovative methods developed by the author for enhanced well flow analysis. Mathematical models of various flow schemes and three well flow software are described. The software WT is designed for well test data analysis in multilayer geological formations under unsteady pumping/recharge/recovery, free-flow, slug, packer and interference test conditions. The software WF is reduced to the predefined fluxes in the selected model layers but considers the effect of maximum 4 straight line fix head or barrier boundaries. The program CW simulates the 3D steady-state flow to and in the collector well discharging a homogeneous, anisotropic aquifer. The latter is recharged by either circular or straight line boundary. The software HC is developed for parameter optimization and can be used in association with the WT software. 27 independent well flow solutions are selected from the literature to validate the software WT, WF and CW. 12 case studies under various test conditions are presented. The number of applied model layers ranges from 1 to 109. The automatic calibrations concluded with acceptable model fit and yielded reasonable formation and well parameters.
