Reproduce Wettability Alteration of Low-Permeable Outcrop Chalk
Proceedings of SPE/DOE Improved Oil Recovery Symposium, 1998Summary A total of 41 chalk core plugs, cut with the same orientation from large blocks of outcrop chalk, have been aged in crude oil at 90 °C for different time periods, in duplicate sets. Different filtration techniques, filtration temperatures and injection temperatures were used for the crude oil.

Laser-induced wettability alteration in limestone rocks
Materials Today Communications, 2018Abstract Alteration of wettability is pre-eminent in improving the efficiency of various industrial applications related to the materials such as metals, polymers, and rocks. We demonstrate wettability alteration in limestone porous rocks using different lasers with different wavelengths and energy.

Atomic Force Microscopy Study of Wettability Alteration
SPE International Symposium on Oilfield Chemistry, 2005Abstract Waterflooding recovers little oil from fractured carbonate reservoirs, if they are oil-wet or mixed-wet. Surfactant-aided gravity drainage has the potential to achieve significant oil recovery by wettability alteration and interfacial tension (IFT) reduction.

Wettability Alteration in High Temperature Carbonate Reservoirs
SPE Improved Oil Recovery Symposium, 2014Abstract The objective of this study is to develop strategies to improve oil recovery in highly fractured carbonate reservoirs at high temperatures (100°C and above). Such reservoirs usually contain high salinity and high hardness formation brines.

Wettability Alteration in a Tight Oil Reservoir
Energy & Fuels, 2013In fractured reservoirs, the efficiency of water flood is governed by spontaneous imbibition of water into oil-containing matrix blocks. When the matrix is oil-wet or mixed-wet, little oil can be recovered by imbibition. The objective of this work is to identify chemicals that can be added to the injection water that can induce imbibition into an ...

Modeling Wettability Alteration in Naturally Fractured Reservoirs
Proceedings of SPE/DOE Symposium on Improved Oil Recovery, 2006Abstract Laboratory surfactant and hot water floods have shown a great potential in increasing oil recovery for reservoirs that are naturally fractured and have low permeability mixed-wet matrix rocks. Fractured, mixed-wet formations usually have poor waterflood performance because the injected water tends to flow in the fractures and ...

Capillary driven flow in wettability altered microchannel
AIChE Journal, 2017The capillary driven flow of water inside a microchannel with altered wettabilities is experimentally investigated and modeled theoretically. The surfaces of the PDMS made microchannel are exposed to oxygen plasma, rendering the surfaces increasingly hydrophilic, which provides the driving force for the flow.

Mimicking wettability alterations using temperature gradients for water nanodroplets
Nanoscale, 2017A sessile water droplet moves from colder to warmer regions on a hydrophobic substrate, guided by the coupled effects of wettability and evaporation, demonstrating ‘reverse-Marangoni effect’.
