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...
