The present disclosure describes methods and systems, including computer-implemented methods, computer-program products, and computer systems, for providing 360-degree well core sample photo image integration, calibration, and interpretation for modeling of reservoir formations and lithofacies distribution. One computer-implemented method includes 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. |

1. A computer-implemented method comprising:
receiving a dimensionless 360-degree well core sample photo image; geospatially anchoring, by a computer, the received dimensionless 360-degree well core sample photo image by enhancing the dimensionless 360-degree well core sample photo image with three-dimensional geospatial positioning data; decomposing, by a computer, the geospatially-anchored 360-degree well core sample photo image along strips at a particular depth measurement into a set of color numerical array samples as a first intermediate data set, wherein higher color complexity along a strip results in a higher number of color numerical array samples for the particular depth measurement; transforming, by a computer, the set of color numerical array samples into a formation image log as a secondary intermediate data set; 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 calibrated formation image log. |
