The book is devoted to the mathematical model and solution technique for the spontaneous potential well-logging. The corresponding mathematical model should be the boundary value problem of quasi-harmonic partial differential equations with inhomogeneous interface conditions. In axi-symmetric situation, at the crossing point of multiple interfaces, the compatible condition is usually violated so that it is not possible to get a solution to the boundary value problem in the sense of piecewise \(H^1\) space. In the book the solution is sought in piecewise \(W^{1,p}\) space \(1 < p < 2.\) In the book, in the axi-symmetric situation it is demonstrated the well-posedness of the corresponding mathematical model and arc developed three efficient schemes of numerical solution to meet the need of practical computation.
