A distance-based capillary biosensor using wettability alteration

Lab on a Chip, 2021
A visual quantitative distance-based biosensor through capillary action is proposed, which converts the wettability changes caused by the target molecules into a capillary rise height signal without any manufacturing technology.

A Model for Wettability Alteration in Fractured Reservoirs

International Petroleum Technology Conference, 2013
Abstract Many of the world's oil reservoirs are naturally fractured. Injected water will flow into this highly permeable network and not sweep the matrix containing most of the oil. Spontaneous imbibition can drive oil into the fractures by capillary forces.

Wettability Alteration with Silica Aerogel Nanodispersion

Journal of Dispersion Science and Technology, 2013
This work studies the wettability alteration using nanoporous silica aerogels for enhanced oil recovery. Water wet flat glass and outcrop sandstone are used for this aim. Modified silica aerogels are synthesized with cheap water glass as the precursor, and ambient pressure drying method.

Wettability Alteration of Fractured Carbonate Reservoirs

SPE Symposium on Improved Oil Recovery, 2008
Abstract Oil can be recovered from fractured, initially oil-wet carbonate reservoirs by wettability alteration with dilute surfactant and electrolyte solutions. The goal of this work is to study the effect of salinity, surfactant concentration, electrolyte concentration, and temperature on the wettability alteration and identify ...

The Effect of Fluoropolymer on Wettability Alteration of Sandstone at Elevated Temperatures

Journal of Surfactants and Detergents, 2016
AbstractGas condensate reservoirs are generally recovered using a pressure depletion drive. Gas can condensate into the liquid phase near the wellbore region when the reservoir pressure falls below the dew point pressure, which can kill gas deliverability.

Reproduce Wettability Alteration of Low-Permeable Outcrop Chalk

Proceedings of SPE/DOE Improved Oil Recovery Symposium, 1998
Summary 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.

Charge Control and Wettability Alteration at Solid-Liquid Interfaces

SPE Improved Oil Recovery Symposium, 2014
Abstract Most solid surfaces acquire a finite surface charge upon exposure to aqueous environments due to desorption and/or adsorption of ionic species. The resulting electrostatic forces play a crucial role in many fields of science, including colloidal stability, self-assembly, wetting, and biophysics as well as technology.

Wettability alterations due to aging in crude oil; wettability and Cryo-ESEM analyses

Journal of Petroleum Science and Engineering, 2003
Abstract Several studies of fluid distribution and wettability on the pore scale have been reported, but to our knowledge, none of them have attempted to obtain quantitative measurements. In this paper, quantitative wettability results from Cryo Environmental Scanning Electron Microscopy (Cryo-ESEM) are reported and compared to wettability ...
