Research topic: "Effect of Ultrasonic Waves on Multiphase Flow in Porous Media"

Thesis

Tarek's research focuses on the effects of high frequency sound waves on multiphase in porous media and oil recovery. His work can be divided into two parts: (1) Static (capillary) imbibition experiments, and (2) Dynamic (injection) experiments. 

A series of capillary imbibition experiments under ultrasound were conducted on sandstone plugs using a focused ultrasonic beam. The aim is to identify the governing mechanisms and clarify the relative effects of them on ultimate recovery and production rate. Capillary imbibition is a very gentle process that is primarily dominated by interfacial tension, wettability and fluid density. The absence of viscous forces makes it a suitable experiment for highlighting the effect of ultrasound on interfacial forces. During the process, the wetting fluid percolates along the pore walls, and invades the smallest pores. As a consequence, the non-wetting phase is forced into adjacent pores. Ultrasonic energy enhances the capillary imbibition recovery of oil for different fluid pairs. The air-water experiments showed less amount of water-imbibed water when ultrasound is applied. Trapped bubble oscillation and acoustic dispersion were considered possible reasons for this.

The ultrasonic energy is expected to change rock and liquid properties as well as liquid-liquid, liquid-rock, and gas-liquid interactions. This will eventually cause an improvement in the oil flow yielding faster and higher oil recovery. To clarify the alterations in the interfacial forces under ultrasonic waves, Hele-Shaw experiments were conducted. Some snapshots are shown below.
