Abstract
A well logging instrument, embodied both in drillstring and in wireline logging systems, is caused to traverse an earth borehole and to generate lithology-related data. First and second lithology compositional models are constructed from such data and are combined to determine a range of possible solutions having an upper limit defined by a pure component model and a lower limit defined by a proportional mixture model, thus allowing the maximum concentration of any lithologic component to vary between 0% and 100%. The exact value of the lithology lies between the upper and lower limits in the range of values and can be calibrated to a mineralogic analysis of actual core samples or drill cuttings.
