... Abstract Pore radius and pore surface wettability affect capillary pressure and relative permeability functions which, in turn, affect fluid distribution in the flow channels and the outcome of improved and enhanced oil recovery in the reservoir. The contact angle between each pair of fluids...

... Abstract The wettability of organic-rich mudrocks has significant impacts on multiphase fluid flow and hydrocarbon recovery. Since kerogen can constitute a significant volumetric fraction of mudrocks, the wettability of kerogen can considerably affect the wettability of organic-rich mudrocks...

... of the effect on abundant unconventional shale. Exposure of shale samples to compressed hydrogen gas at in-situ conditions would help determine changes in wettability, permeability, and porosity. Sample properties are measured before and after exposure. Another interest is the effect of hydrogen exposure...

... wettability alteration, ability to increase oil recovery during core soaking, and effect on CO2-oil interfacial tension (IFT). All three surfactants exhibited good solubility in CO2 (roughly 1 wt% at pressures of 2000-5000 psi). Contact angle experiments demonstrated that the CO2+surfactant solutions can...

... with drilling mud. Furthermore applications can be altering the formation and casing wettability, especially when drilling operations involves drilling with oil-based mud, where the production zone will be most likely oil-wet. Oil wet formation can reduce cement bonding with formation, which could lead...

..., this process and its controlling factors are investigated through a comparative study of three shale samples that have different types of pore systems and wettability. An integrated method of imbibition and multiscale imaging was applied, and a modified oleic tracer that can better represent oil flow was used...

Finally, the efficiency of drag reduction after adding the LNF was evaluated. The result showed that imbibition and nuclear magnetic resonance...

... Abstract Multiphase flow through fractures is common in many fields, yet our understanding of the process remains limited. In general, this is because some factors which separate multiphase flow from single-phase flow (interfacial tension, wettability, residual saturation) are difficult...
