Claim One:
1. A method for interpreting petrophysical measurement data, comprising: in a computer, arranging measurements of at least one physical property of formations made by at least one petrophysical measuring instrument into a matrix representing the measurements and selecting a number of unobserved factors for factor analysis; in the computer, performing factorization of the measurements matrix into the selected number of factors; in the computer, performing rotation of the factorization results; in the computer, determining whether factor loadings for each factor have achieved a simple structure; in the computer, at least one of associating each of the factors with a physical parameter of the formations and adding one to the number of factors and repeating the performing factor analysis and the determining factor loadings until all factors have achieved a simple structure such that the each of the number of factors is associated with a physical parameter of the formations.
