... Abstract The pore structure of unconventional gas reservoirs, despite having a significant impact on hydrocarbon storage and transport, has historically been difficult to characterize due to a wide pore size distribution, with a significant pore volume in the nanopore range. A variety...

...) determined the pore size distributions. A robust, detailed tomography procedure using a dual-beam (Scanning Electron Microscope and Focused Ion Beam, also called SEM-FIB) instrument successfully characterized the submicron-pore structures. SEM images revealed various types of porosities. Pores on a scale...

The artificial samples, with well-characterized and nearly uniform pore structure, serve as a calibration standard for preliminary-efforts at inverting the Nuclear Magnetic Resonance relaxation data on the Gas Sand core samples to obtain...
