Rheology studies the flow and deformation of the fluid. Interfacial rheology studies the same for interfacial layers.
Studies show the influence of EOR agents on the reservoir rock wettability. Studies are not considering the reservoir conditions i.e. high pressure.
There are three commonly used wettability measurement techniques for oil reservoir characterization; Contact angle, Amott-Harvey, and USBM.
Interfacial rheology studies the flow properties of liquid interfaces.
Superhydrophobic surface is defined by having the static water contact angle above 150 ° and contact angle hysteresis less than 5 °.
Surface free energy can be calculated through contact angle measurements. Automated instruments are available.
Plasma treatment is an often-used process prior to coating, printing or gluing to improve the wettability of the material.
There are three contact angle measurement methods for superhydrophobic surfaces; static, advancing/receding and roll-off angle.
Graphene oxide is hydrophilic and thus dispersible to water. Dispersibility makes the solution-based deposition of graphene oxide possible.
