The traditional way of assessing etching properties can be time-consuming. But there are faster ways. Here we present a method that will help you assess the etching effects in one single wash cycle and in less than an hour.
Coatings are typically evaluated by methods such as laboratory drawdown. Contact angle measurement can provide a more quantitative approach.
A basic requirement of any coating is that it should form a uniform, defect-free surface. Surface and interfacial tensions play a key role in that.
To avoid potential adverse effects, it is relevant to study how nanoparticles interact with their surroundings. Here we present examples of how nanoparticle interaction with a variety of surfaces can be analyzed.
Contact angle hysteresis is often measured with so-called tilting cradle or plate method. The measurement can be done either manually or automatically.
Most commonly used methods to study reservoir wettability are Amott-Harvey, USBM, and sessile drop contact angle.
Dynamic contact angle measurements with the needle method has been automated for reliable and repeatable results.
Working in a surface science lab, you surround yourself with analysis equipment that you need to progress in your work. The benefits of running combination measurements could be three-fold.
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.
