1. A method of optimizing the correlation of well log data, comprising: identifying a geological signature in well log data from a reference well; identifying well log data from at least one target well; calculating a plurality of solutions from the reference well log data and the at least one target well log data, each of the plurality of solutions having an associated cost measure; and displaying the solution having the least associated cost measure on the at least one target well log data as an optimal solution, wherein the optimal solution comprises a mapping of the geological signature from the reference well log data.
