Experience of Constructing and Applying of Petrophysical Inversion Algorithms and their Parameters Adjustment

Existing systems intended for interpretation of petrophysical data can be divided into ‘quick-look’ and ‘indepth’ systems. The principal advantage of all latter ones is a built-in module (in various realizations) that allows performing petrophysical inversion – a major achievement of modern data interpretation. Another line of development of petrophysical interpretation – various ways of logging methods internormalization – is of not less importance. This approach was first proposed by Wyllie and Zalyaev. Its necessity is stipulated by information concerning petrophysical interrelationships, which is in most cases statistically not-reliable or incomplete. In this report an issue of synergy of both these lines is reviewed and results of its implementation are given.
