Predicting Effective Diffusion Coefficients in Mudrocks Using a Fractal Model and Small-Angle Neutron Scattering Measurements
Autor: Artem Feoktystov, Vitaliy Pipich, Niko Kampman, Leon Leu, Elke Jacops, Andreas Busch, Pieter Bertier, Marc Aertens, Gernot Rother, Jon F. Harrington
Publikováno v: Water resources research 54(9), 7076-7091 (2018). doi:10.1029/2018WR023425
The determination of effective diffusion coefficients of gases or solutes in the water‐saturated pore space of mudrocks is time consuming and technically challenging. Yet reliable values of effective diffusion coefficients are important to predict

The pore structure of organic rich mudrocks is associated with both inorganic and organic constituents. The contribution of organic matter to the pore structure has been investigated on Posidonia and Bossier Shale samples having different organic car

Sixth EAGE Shale Workshop, Bordeaux, France, 2019-04-28-2019-05-01
Small angle neutron scattering (SANS) and nitrogen low-pressure adsorption (LPS) have been used to characterise the pore structure of two organic lean mudrocks, Opalinus Clay, Mont Terri, Switzerland and Carmel Claystone, Utah. This was done in order

In most cases, the analysis of small-angle and wide-angle X-ray scattering (SAXS and WAXS, respectively) requires a theoretical model to describe the sample's scattering, complicating the interpretation of the scattering resulting from complex hetero

During imbibition, initially connected oil is displaced until it is trapped as immobile clusters. While initial and final states have been well described before, here we image the dynamic transient process in a sandstone rock using fast synchrotron-b

Fast X-ray Micro-Tomography of Multiphase Flow in Berea Sandstone: A Sensitivity Study on Image Processing
Autor: Ryan T. Armstrong, Leon Leu, Steffen Berg, Frieder Enzmann, Michael Kersten
Publikováno v: Transport in Porous Media. 105:451-469
Synchrotron-based fast micro-tomography is the method of choice to observe in situ multiphase flow and displacement dynamics on the pore scale. However, the image processing workflow is sensitive to a suite of manually selected parameters which can l
