Ultrasonic Waves on Drilling Fluid Foaming
The aim is to introduce a new technology of removing foam in drilling fluids by subjecting ultrasonic waves to it. For this research, the drilling fluid formulated is water-based. The aim is to observe the effects of ultrasonic waves on the foam that is produced in a certain drilling fluid. Ultrasonic waves have the capability of reducing foam in fluids since energy waves collapse and expand the foam until the foam is eliminated. The device used is the Herschel UIP1500hd was used to apply the ultrasonic waves to the fluid sample. Then, a Fann 35 viscometer is used to study the rheological characteristics of the drilling fluid. The drilling fluid was formed by following Herschel-Buckley because it is considered the most accurate model of rheological behaviour of drilling fluids with considering yield stress and shear thinning as seen in Figure 1. The aim is to make the most accurate representation of fieldwork and for that this research includes studying the oil volume change of 1%, 2%, and 3%.
