High-resolution computed tomography scan dataset of lower Mount Simon Sandstone samples from the Illinois Basin

Abstract

This dataset encompasses high-resolution computed tomography scans of small samples of the lower Mount Simon Sandstone from the subsurface of the Illinois Basin. Samples were collected as part of various geological carbon storage characterization efforts and publications focusing on the Mount Simon as a storage reservoir, with scanning performed at the National Energy Technology Laboratory. Thirty-seven three-dimensional (3D) volumes at various resolutions are described and presented as a resource that illustrates the pore and grain size distributions, as well as other petrographic characteristics. This high-quality, fine resolution, 3D image dataset of an important carbon storage target rock formation can be utilized by researchers as a training dataset for machine learning algorithms and for further reservoir characterizations.
