A method for characterizing a subsurface formation includes receiving image data of the subsurface formation obtained by a sensor tool and receiving a plurality of non-image data logs, each non-image data log being obtained by a different type of sensor tool. The method also includes performing an electrofacies analysis on the plurality of non-image data logs where the electrofacies analysis includes defining clusters wherein each cluster has a similar property to provide a plurality of electrofacies blocks with each electrofacies block representing a depth interval. The method further includes partitioning the image data into multiple high-resolution depth segments that share a similar property, feature, and/or pattern for each electrofacies block and assigning data from the plurality of non-image data logs into a corresponding high-resolution depth segment to provide a high-resolution data log that characterizes the subsurface formation.

Core-level high resolution petrophysical characterization method

Embodiments include a method that includes extracting a low resolution formation property model and a high resolution formation property model from at least one log. The method also includes splitting the extracted low resolution formation property model into one or more property compositions. The method also includes generating a high resolution virtual core via the low resolution formation property model and at least a second high resolution formation property, the high resolution virtual core utilizing a moving window analysis to accommodate between different resolutions of the second high resolution formation property model and the low resolution property composition.
