An ellipse equation is adopted to estimate the prewear condition of the cross section, and then it is applied to calculate wear. Also, a methodology to generate synthetic tube cross sections with prescribed ovality, eccentricity...

When the analysis is applied to a discrete length of pipe, the cross sections at each end do not contribute...

Our CT results suggest a revision of our earlier interpretation; the process of gas dissolution does not merely follow fingering but is evidently directly...

Previous publications showed that use of high thermal neutron-capture cross-sectional (HTNCC) contrast agents can enhance the sensitivity of neutron logs to the presence of fractures. However, all these studies focus on locating the proppants. In this paper, we introduce a method...

... these restrictions. We simulate drainage, wettability alteration, and imbibition in 2D rock images by use of a semianalytical pore-scale model that represents the identified pore spaces as cross sections of straight capillary tubes. The fluid configurations occurring during drainage and imbibition in the highly...
