Enhanced oil recovery: Why measure wettability at high pressures and temperatures?
Studies show the influence of EOR agents on the reservoir rock wettability. Studies are not considering the reservoir conditions i.e. high pressure.
Enhanced oil recovery: Comparison of oil reservoir wettability measurement techniques
There are three commonly used wettability measurement techniques for oil reservoir characterization; Contact angle, Amott-Harvey, and USBM.
Why is interfacial rheology important?
Interfacial rheology studies the flow properties of liquid interfaces.
What are superhydrophobic surfaces?
Superhydrophobic surface is defined by having the static water contact angle above 150 ° and contact angle hysteresis less than 5 °.
Surface free energy measurements in practice
Surface free energy can be calculated through contact angle measurements. Automated instruments are available.
Contact angle measurements to evaluate plasma treatment efficiency
Plasma treatment is an often-used process prior to coating, printing or gluing to improve the wettability of the material.
Contact angle measurements on superhydrophobic surfaces in practice
There are three contact angle measurement methods for superhydrophobic surfaces; static, advancing/receding and roll-off angle.
How to deposit graphene oxide thin films?
Graphene oxide is hydrophilic and thus dispersible to water. Dispersibility makes the solution-based deposition of graphene oxide possible.
What is required for good adhesion?
Good adhesion is generally required whenever a coating is applied to a surface. A clean surface and good wettability are needed for good adhesion.
