Claim 1:
2. The method of claim 1, wherein performing the typelog alignment for the typelog reference data associated with the plurality of reference wells using multi-stage optimization further comprises:
preprocessing, by the computer system, the typelog reference data, including a rank transformation and multistage smoothing;
performing, by the computer system, a multistage iterative optimization including successive alignment through multiple stages of smoothed data;
when results of the multistage iterative optimization are not acceptable, adjusting at least one of a start depth, an end depth, and a current alignment function; and
when results of the multistage iterative optimization are acceptable, outputting the aligned depth log, including aligned depth markers between the start depth and the end depth.
