Adaptive interpretation of well logging data
The petrophysical invariance determination as an interpretation parameter of well logging data has allowed to move from empirical algorithms («cross-plotting») to the algorithms of interpretation which are based on analytical petrophysical models of reservoirs reflecting set of conditions of their genesis. The principle of petrophysical invariance has allowed to present in generalized analytical form the dependence between interpretation parameters and filtration-capacity characteristics of complex reservoirs. In deficiency of petrophysical information or even in absence of reference layers adaptive tuning of algorithms reduces the number of errors sources.
