After a trial suite of samples from preserved core plugs from all major members of the Bakken petroleum system were re-evaluated, a new core was collected and analyzed. Traditional Dean-Stark porosity and saturation measurements were complimented with advanced fluid pore...

... Abstract An accurate evaluation of the shale oil movability is crucial to its cost-effective exploitation. The objective of this study is to demonstrate a method to analyze shale oil movability by considering the pore structure and the concentrations of different oil states. First, a set...

... mineralogy are used for rock characterization, followed by acquisition of 3D volumes with nanometer resolution for pore scale analysis and generation of digital 3D models. The presence of pore-backs, an artefact often observed in focused ion beam scanning electron microscopy (FIB-SEM) images, demands...

.... Abstract Water-oil displacement is an important process that occurs in a shale matrix after hydraulic fracturing and in water-based enhanced oil recovery. Current understanding of this displacement process is limited because of the complicated pore structure and surface properties in shale. In this work...

...-SEM microscopy is used to reconstruct a 3D volume where organic matter, pores and minerals can be identified and segmented. Thin sections are then micro-machined by FIB-SEM, mounted on a TEM grid and thinned down to electron transparency (about 100 nm). High-magnification micrographs highlighting...
