1. A computer-implemented method comprising: receiving a 360-degree well core sample photo image; geospatially anchoring, by a computer, the received 360-degree well core sample photo image; decomposing, by a computer, the geospatially-anchored 360-degree well core sample photo image into a color numerical array; transforming, by a computer, the color numerical array into a formation image log; calibrating, by a computer, the formation image log for consistency with additionally available data; and generating, by a computer, 3D lithofacies interpretation and prediction data using the formation image log.
