The stacked rock cuttings were centrifuged, to significantly remove the excess fluids at the cuttings surface, allowing accurate determination...

... Abstract Eocene sandstones in the Huanghekou Depression, Bohai Bay Basin, China are characterized by highly variable macroscopic petrophysical properties and heterogeneous microscopic pore structures, and thus control fluid flow behavior and remaining oil distribution in porous rock...

The petrophysical data including core porosity-permeability are also used to characterize the pore types and other diagenetic features. The present study exhibits that Tuba Formation has...

... Abstract Pore size distribution (PSD) is one of the most important properties for characterizing the pore systems of porous media. Typically, a single aspect ratio ( α _ ), defined as the ratio of the short-axis diameter over the long-axis diameter of a pore, is assumed (i.e., set...
