Summary: This research investigates the impact of magnetite nanoparticles on the surface properties of silica during asphaltene precipitation. The results show that heteroatoms and aromatic rings in asphaltene affect its agglomeration and adsorption process. The presence of magnetite nanoparticles reduces the contact angle of pure silica upon asphaltene precipitation, making the silica surface preferentially oil-wet.

Summary: The use of a novel non-fluorinated benzoxazine monomer has been shown to effectively shift the wettability of sandstone rocks from strongly water-wet to an intermediate-wet state, thereby mitigating water blockage in gas producing wells. This environmentally friendly and cost-effective chemical treatment can increase gas relative permeability while reducing residual water saturation, offering a solution for low-permeability gas reservoirs where water blockage is a concern.

Summary: The study revealed that increasing surface roughness makes carbonate and sandstone rocks more susceptible to gypsum deposition, while dolomite and sandstone rocks are more prone to gypsum scale formation compared to calcite and anhydrite. Additionally, as roughness and salinity increase, the rocks show super-hydrophilic characteristics, indicating an increased affinity for gypsum scale deposition.

Summary: The study discusses the influence of surface roughness frequencies and parameters on mixed wetting and its transitions. It was found that while all roughness frequencies contribute to net roughness parameters, not all of them affect wettability transitions. Parameters such as Rz and LSm were identified as predictors for spatial roughness frequencies that dictate transitions to different wettings states.

Summary: In gas condensate reservoirs, a fluoro-chemical foam treatment technique is introduced to alleviate the condensate build-up, by altering the wettability of the reservoir rock surface. Experimental results show that the treatment can significantly increase contact angles and improve gas relative permeabilities in sandstone and carbonate cores.

Summary: By chemically modifying the surface of silica nanoparticles, colloidal stability in high salinity and high temperature conditions was achieved, and the wettability of carbonate reservoirs was changed from oil-wet to water-wet. The modified nanoparticles, combined with surfactants, altered the water-phase contact angle on calcite, indicating a shift in wettability for both light and heavy crude oil. The reduced water-phase contact angle is beneficial for secondary oil recovery and helps destabilize water-in-crude oil emulsions.

Summary: Oil reservoirs with hydrophobic surfaces have a significant impact on flow functions at the macro-scale. However, quantitative measurement of CO2 in oil-wet formations remains challenging due to inconsistent experimental data and uncertainties in predicting wettability. In this study, NMR technology was used to measure and analyze the wettability indices in an oil-wet San Saba, providing comprehensive data on the effect of pore-scale properties on flow functions. These findings contribute to the implementation of carbon capture and storage (CCS) and enhanced oil recovery (EOR) projects in oil-wet reservoirs.

Summary: The experimental investigation showed significant improvements in boiling heat transfer coefficient and critical heat flux at a mass fraction of 0.1% for Al2O3 and TiO2 nanoparticles in water. An increase in mass fraction improved the surface wettability of nanofluids and reduced the surface roughness of the boiling surface. Al2O3-water nanofluids exhibited better boiling performance compared to TiO2-water nanofluids.

Summary: Superhydrophobic surfaces are achieved on 6082 aluminum alloy substrates using low-cost chemical surface treatments and fluorine-free alkyl-silane coating deposition. Different surface treatments, such as boiling water, HF/HCl, and HNO3/HCl etching, significantly influence the micro-nano structure and wetting behavior. A two-step procedure involving roughening treatment and surface chemical silanization can easily tailor the superhydrophobic behavior of the aluminum alloy surface.
