Abstract

The most widely used methods of log deconvolution have focussed on the modelling of the tool response function and the design of practical in- verse filters. Their success has been dictated by the degree to which they overcome the problems of measurement error, imprecise knowledge of the form of response functions and associated stochastic and non-linear properties. As an alternative approach, cored supply a desired output signal of porosities to volution of input logs. This operation has the computed in-place, with accommodations of local lithology factors, and that its performance can against the core porosities used as a standard.
