...) floods at low, intermediate, and high initial water saturations. Additionally, we present a micron-scale visualization of an ASP flood under UV light to observe the distribution of surfactant around an oil bank at the pore scale. We found that oil banks formed even during very unfavorable displacements...

... and we normalize the graph relation attributes using Box-Cox transformation. We train the GeoDIN framework to predict oil and water saturation dynamics in space and time. When benchmarked with full-physics simulation, the INs ran on two V100 graphics processing units and substantially accelerated...

...) proposed a weak form TgNN, which added the weak form formulation of the PDEs into the loss function to tackle the strong discontinuities in two-phase flow problems. The Buckley-Leverett equation in the above two works, however, is a simplified equation that describes water saturation displacement...

...Kai Cheng; J. Alex Zumberge; Stephanie E. Perry; Patrick M. Lasswell; Themi Vodo Summary Legacy crushed rock analysis, as applied to unconventional formations, has shown great success in evaluating total porosity and water saturation over the previous three decades. The procedure of crushing rock...

... primarily from changes in water saturations, the estimated boundary-arrival times resemble the actual water-front-arrival times. Hence, combined with classical immiscible displacement theory, the estimated arrival times can support a practical, model-independent, quantitative estimation of water saturations...
