Abstract
The paper presents a mathematical model, numerical solutions and results for 3D fields from dc sources in a horizontal well drilled in a layered conductor. The model simulates the behavior of apparent resistivity in the well and its sensitivity to instrument parameters and variations in formation resistivity and thickness in terms of a boundary-value problem. BVP approximation is obtained as finite volume and iteration solutions to systems of grid algebraic equations using fast incomplete factorization solvers.
