Abstract

We consider a variant of automatic correlation between well sections based on construction of multidimensional functions of differences between fragments of logs. The solution is obtained either by successive correlation between the boundaries based on the projective model of Haites and definition of the boundary position at the minimum of the difference function or by construction of the lines of optimal trajectories on a 2D Zhekovskii's plot. These algorithms are implemented as a program package for original interpretation of well data and as a plug-in for the automatic correlation module of the Schlumberger Petrel software using the Ocean development tools.
