Abstract
A method of computer generating a subsurface characteristic model which is substantially consistent with readings taken in a well with a well logging device. A set of actual measurement values which represent readings taken over a given depth interval of a well is derived. An initial trial model of the subsurface characteristic under investigation is then selected. Next, a set of simulated measurement values is generated by applying the approximate response characteristic of the logging device to the discrete trial model. The simulated measurement values are compared with the actual measurement values and an error function is generated in accordance with the comparison, the error function reflecting the comparison taken over a substantial portion of the given depth interval. The model is then modified in a manner which tends to minimize the error function.
