Claim 0:
1. A computer-implemented method, comprising:
receiving first well log data associated with a key master well;
receiving formation data identifying depths of tops of formations confirmed in the key master well;
generating merged key master well and formation data in a dynamic time warping (DTW)-readable format by merging the first well log data with the formation data;
identifying a first shallowest formation top using the merged key master well and formation data;
receiving second well log data associated with a training well located in geographic proximity to the key master well;
formatting the second well log data into the DTW-readable format;
identifying a second shallowest formation top using the second well log data;
normalizing the merged key master well and formation data and the second well log data;
executing, using the normalized merged key master well and formation data and the formatted second well log data, the first shallowest formation top, and the second shallowest formation top as DTW function inputs, a DTW function to generate indices associated with depths of formation tops, wherein executing the DTW function includes an iterative process of well log condensing and de-condensing to match peaks and troughs in the first well log data and second well log data, the condensing and de-condensing spatially adjust peaks and troughs of formations identified in the first well log data and the second well log data; and
predicting, using the generated indices, predicted geological formation tops for the training well.
