Many techniques exist for computer-aided interpretation of geological, geotechnical, and resource quality parameters from downhole geophysical data. Usually the measurements at any one depth are interpreted without regard to the data at other depths. However, in some circumstances, it is desirable to generate interpretations that conform to a known stratigraphic succession. Accordingly, this paper describes progress towards the development of an a posteriori stratigraphic correction procedure. The correction procedure operates on a preexisting interpretation of stratigraphic units based on their wireline signatures alone. The inputs are the stratigraphic order itself, and minimum, maximum, and standard (average) thicknesses defined for each of the stratigraphic units. Correction is effected in three stages, targeting successively (a) layers that exceed the minimum thickness, (b) thin layers, and (c) excessively thick layers. During each stage, a directed trial-and-error process resolves stratigraphic conflicts between adjacent layers. The process is expedited if a petrophysically distinct “marker bed” occurs in the sequence. The correction algorithm has been illustrated in the context of geotechnical modelling at the German Creek coal mine, Queensland. Results achieved to date have been sufficiently encouraging to warrant a trial implementation of computer-aided geotechnical interpretation at the mine.
