INTEGRATED WELL FLOW MODELING - 2nd edition

This book summarizes the author''s methods and software for mostly analytical well flow analysis. The software WT along with the calibration software HC are designed for well test data analysis in multilayer or fractured formations under unsteady pumping/recharge/recovery free-flow slug packer and interference test conditions. The option of multi-screened wells is included. The software WF provides unsteady solution for well field operation with predefined fluxes in the tapped model layers and 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 horizontal or radial collector wells discharging a homogeneous anisotropic aquifer. The latter is recharged by either circular or straight line boundary. Recharge from the fix head top is also allowed. The software WT and CW include the effects of nonlinear screen and wellbore processes. The software WT WF and CW are validated against 30 independent well flow solutions. 12 case studies for vertical wells are presented with model layers ranging from 1 to 109.
