    How to alter wettability in carbonate reservoir?

    Carbonate reservoirs are characterized as intermediate to oil- wet. Altering the wettability of the carbonates has been proposed as one of the main mechanisms for enhanced oil recovery.

    Graphene oxide for biosensors

    Biosensing is a crucial part of human well-being as early detection of diseases requires highly sensitive and selective methods. New materials, such as graphene oxide, are evaluated for improved biosensor performance.

    3 examples of how to utilize high pressure tensiometer

    Different enhanced oil recovery methods are used to alter the wettability of the reservoir rock. To study the wettability alteration at the reservoir conditions, an instrument where the measurements can be done at high pressures and temperatures are needed.

    How to study the wettability of the contact lens?

    Contact lens should support a continuous tear film for optimum visual clarity. It should also resist the sorption of tear components as deposition can lead to decreased visual clarity and discomfort. Wettability of the surface affects both the tear film as well as biocompatibility of the lens.

    Why is wettability important in enhanced oil recovery?

    In enhanced oil recovery wettability plays an important role as that determines the interactions between the solid (rock) and the liquids in the reservoirs (crude oil, brine). Wettability has been recognized as one of the key parameters controlling the remaining oil-in-place.

    What is wettability?

    Wettability is the preference of a liquid to be in contact with a solid surrounded by another fluid (liquid or gas). Depending on the application, wettability can be wanted or not.

    What is graphene oxide?

    Graphene oxide (GO) is the oxidized form of graphene. Graphene oxide is easy to process since it is dispersible in water and other solvents. Due to the oxygen in its lattice graphene oxide is not conductive, but it can be reduced to graphene by chemical methods.

    What does self-cleaning mean?

    A self-cleaning surface is any surface with the ability to readily remove any dirt or bacteria on it. Self-cleaning surfaces can be divided into three different categories; superhydrophilic, photocatalytic and superhydrophobic.

    Why is contact angle important?

    In industry, wettability is important for example when manufacturing electronics or when planning how to extract oil from the oil reservoir. In all these applications, knowing the contact angle value gives a strong indication on the performance of the product or a successfulness of the process.
