... Abstract This paper describes an Excel spreadsheet used to solve a challenging transient heat transfer problem in a well. A large number of unknown temperatures are solved numerically as a function of time on an R-Z grid. Time steps are controlled by a macro and the formulation is fully...

... prior to production was obtained by solving the diffusivity equation for conductive heat transfer during the circulation period. This provided the initial condition for solving the continuity equation for convective heat transfer during production by the method of characteristics. The application...
