Universal Stochastic Multiscale Image Fusion: An Example Application for Shale Rock

We develop a general solution for merging multiscale categorical spatial data into a single dataset using stochastic reconstructions with rescaled correlation functions. The versatility of the method is demonstrated by merging three images of shale rock representing macro, micro and nanoscale spatial information on mineral, organic matter and porosity distribution. Merging multiscale images of shale rock is pivotal to quantify more reliably petrophysical properties needed for production optimization and environmental impacts minimization.

Abstract Spatial data captured with sensors of different resolution would provide a maximum degree of information if the data were to be merged into a single image representing all scales.
