Multiple choice

What is the term used to describe the process of injecting fluids into a reservoir to maintain or increase reservoir pressure?

  1. Pressure maintenance

  2. Waterflooding

  3. Gas injection

  4. Polymer flooding
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Pressure maintenance involves injecting fluids, such as water or gas, into a reservoir to replenish the energy and maintain reservoir pressure, enhancing hydrocarbon recovery.

Multiple choice

What is the process of converting organic matter into biogas called?

  1. Photosynthesis

  2. Combustion

  3. Anaerobic Digestion

  4. Hydrolysis
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Anaerobic digestion is the process of breaking down organic matter in the absence of oxygen. This process produces biogas, which is a mixture of methane and carbon dioxide, and can be used as a renewable energy source.
