Viewing a reservoir at the grain and pore scale results in enhanced understanding, by providing information on porosity distribution, organic material volume, and organic material pore textures. This presentation describes the methodology and results of an unconventional reservoir study which identified the distribution of porosity and organic matter (OM), as well as the relationship between porosity and permeability. Sixteen samples from the Cretaceous (Cenomanian/Turonian) Eagle Ford Formation were collected from four conventionally cored wells located in Maverick, Dimmit, LaSalle and Atascosa counties in south Texas, USA. Our dataset comprises both 2D scanning electron microscopy (SEM) images and 3D Focused Ion-Beam Scanning Electron Microscopy (FIB-SEM) volumes.
