Wettability and Wettability Tests
2015Abstract Wettability is a fundamental property that controls fluid distributions within porous media and has a major impact on capillary behaviour, core electrical measurements, relative permeability behaviour and residual saturations. This chapter describes the sample preparation methods, test equipment, test procedures and data reporting ...

The low recovery of hydraulic fracturing fluid in unconventional shale reservoirs has been in the centre of attention from both technical and environmental perspectives in the last decade. One explanation for the loss of hydraulic fracturing fluid is fluid uptake by the shale matrix; where capillarity is the dominant process controlling this uptake ...

Wettability Quantification - Prediction of Wettability for Australian Formations
International Petroleum Technology Conference, 2011Abstract As a rock-fluid interaction property, wettability is well recognized to influence the flow in multi-phase systems such as hydrocarbon reservoirs. In the laboratory, wettabilty measurements are made according to certain standard procedures and the results are expressed as indices for comparative purposes ...

Reversibly switchable wettability
Chem. Soc. Rev., 2010This critical review outlines the current state-of-the-art research on the reversibly switchable wettability of surface brought about by external stimuli and the exchange of counterions. Chemical composition and surface topography are the two key factors in the wettability of solid substrates.

Wettability of PEDOT:PSS films
Soft Matter, 2016Conducting polymers such as poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PSS) are increasingly used to interface electronics with biology. Their wettability, however, remains poorly understood. We show that the frequently-used sessile drop technique yields results that are strongly dependent on the experimental conditions (measurement ...

Small, 2015
Ionic liquids (ILs) have become particularly attractive recently because they have demonstrated themselves to be important construction units in the broad fields of chemistry and materials science, from catalysis and synthesis to analysis and electrochemistry, from functional fluids to clean energy, from nanotechnology to functional materials.

Wettability of Heterogeneous Substrates
physica status solidi (a), 2001Incomplete organic monolayers grafted on silicon wafer are characterized by spectroscopic ellipsometry (SE) using the Bruggeman effective-medium approximation. The formation of the monolayer, as a condensed liquid (LC*) phase, is investigated. The time evolution of the surface fractions occupied by the different phases allows the determination of a ...

Langmuir, 2010
A simple method for the fabrication of tunable surfaces with wettability that can be manipulated rapidly and reversibly from superhydrophilicity to superhydrophobicity is reported. A polyelectrolyte multilayer (PEM) was deposited on a rough substrate, and via ion exchange of the counterion in the PEM, the water contact angle of the surface was switched

Combined Wettable/Non-wettable Filter for Mist Purification
Chemical Engineering & Technology, 2001Previous studies by Agranovski and Braddock [1] show that wettable filters are very efficient at collecting small liquid aerosols. However, a major problem associated with wettable filters is the breakthrough process associated with the destruction of film covering the fibres, and the removal of relatively large droplets by the carrier gas passing ...
