The video discusses traditional oil extraction methods and introduces innovative techniques using MRI scanners and micro bubbles to improve oil recovery. Research teams from Nottingham Trent and Aston Universities are developing these methods with funding from the Engineering and Physical Sciences Research Council. The work is in the laboratory stage but shows promise for significant advancements in oil extraction.

What is the primary challenge with the traditional method of oil extraction?

• It is too expensive.

• It is harmful to the environment.

• It requires too much manpower.

• It only recovers a small amount of oil before water re-emerges.

What technology are the research teams using to improve oil extraction?

• Magnetic resonance imaging (MRI) scanners

• Ultrasound imaging

• X-ray machines

• Thermal imaging cameras

What is the purpose of using gas-filled microbubbles in the research?

• To reduce the cost of extraction

• To create a 3D image of oil deposits

• To prevent environmental damage

• To increase the speed of oil extraction

Which university is responsible for designing the microbubble fluids?

• University of Oxford

• Aston University

• University of Cambridge

• University of Nottingham

What is the potential impact of the research on oil extraction?

• It could significantly improve the efficiency of oil extraction.

• It could eliminate the need for drilling.

• It could make oil extraction more environmentally friendly.

• It could reduce the global demand for oil.
