Ultrasonic Technology for Enhanced Oil Recovery
Overview of Ultrasonic EOR
and its possible deployment in Kuwait oil ﬁelds
1- What is Ultrasonic EOR?
Ultrasonic EOR is a physical EOR method which uses wave treatment that may or may not
be combined with chemical treatment to affect the well and reservoir leading to high oil
2- Ultrasonic technology's mechanisms to enhance oil production
Ultrasonic tool converts longitudal oscillation into radial which affect the well-bore perforation
and the reservoir leading to:
1- Enhancement of ﬂow of oil through the rock into the pumping pool
2- Reduced viscosity
3- Diminishing capillary forces
6- Coalescence and/or dispersion of oil drops
7- Chemical effects
8- Changes of wettability
3- Equipments used in Ultrasonic Technology for EOR
1- Ultrasonic generator:
- Power supply unit
- Power uint
- Magnetizing unit
- Unit to process the information about ( P, T )

2- Downhole tools:
- Sonotrode PSMS-42
- Register of downhole data
4- Advantages for Ultrasonic EOR deployment
1- Low cost compared to other conventional EOR methods
2- Less energy used compared to other EOR methods
3- Not labor-intensive
4- Low energy consumption
5- Environmentally friendly
6- Treat the formation damage caused by thermal EOR for heavy oil
5- Companies specialized in this technology are:
1- Viatech Ltd.
2- CUT Service Ltd.

6- The potential of deploying Ultrasonic Technology for EOR in Kuwait oil ﬁelds
1- Kuwait's oil reserves include approximately 13 billion barrels of heavy oil and the existing
technologies of enhanced oil recovery (EOR) in Kuwait especially for heavy oil are energy-
intensive, labor-intensive and not environmentally safe compared to Ultrasonic EOR.
2- Most of the oil ﬁelds in Kuwait are mature ﬁelds, that means oil wells in those ﬁelds will
required well intervention work to clean the blockage of the perforations which more
efﬁciently and less costly done through Ultrasonic Technology.
3- The current KOC Lower Fars Project involves the development of the heavy crude oil lying
in the Lower Fars ﬁeld in the north of Kuwait. Crude oil in this ﬁeld is classiﬁed as extra heavy
crude oil and the gravity of the Lower Fars ﬁeld is ranging between 17 API and 11 API while
the viscosity may vary from 10s to 1000s centipoises.
4- Most of the existing technologies of EOR in Kuwait are not applicable for horizontal wells
unlike Ultrasonic EOR technology.
5- Ultrasonic methods of EOR have shown promising results in the recent years.
