Abstract:
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, wherein the cost measure is calculated from a matrix comprising a sum of distances between depth sampled data elements from the reference well log data and data elements comprising the at least one target well log data, the matrix having a length from left to right and a height from top to bottom, wherein the depth sampled elements comprise the geological signature; 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.
