ABSTRACT:
A method of automatically correlating well logs includes selecting well loops from the well logs and creating a set of possible marker positions for each well log in each well loop. From the possible marker positions, alternate marker sets are iteratively selected. A well tie error on each loop is calculated for each selected marker set, summed over all loops and minimized.
