Oil And Gas Industry: The Difference Between A Mud Gas Separator And A Vacuum Degasser
Understanding the difference between a Mud Gas Separator and a Vacuum Degasser is vital for correct well control line-up and safe gas handling.
The main difference between a Mud Gas Separator and a Vacuum Degasser lies in their function and working principle:
- A Mud Gas Separator is used to separate large gas bubbles from drilling mud
- A Vacuum Degasser removes remaining small gas bubbles using a vacuum pump
Let's discuss this further.
Mud Gas Separator (MGS)
- Main function: A primary degassing device to separate free gas (large bubbles greater than 3 mm in diameter) from gas-infested drilling mud
- How it works: Gas-containing drilling mud enters the separator. It flows through a series of baffle plates, creating a turbulent flow. This process increases the contact surface area, allowing free gas to escape from the mud. The separated gas is channeled through a vent pipe to a safe location for combustion or release. The degassed mud is returned to the circulation system.
- When to use: When a large amount of gas intrusion occurs, for example, when formation pressure is higher than mud pressure
- Conclusion: Mud Gas Separator is the first line of defense against free gas in drilling mud
Vacuum Degasser
- Main function: A secondary degassing device to remove dissolved gas or small bubbles remaining in the drilling mud
- How it works: Uses a vacuum pump to create low pressure in the vessel. This low pressure causes dissolved gas and small bubbles to escape from the mud. The extracted gas is released to the atmosphere or into a safe disposal system. The gas-free mud returns to the circulation tank.
- When to use: After the mud has passed through the Mud Gas Separator, this ensures that the mud is completely free of harmful gases that could affect drilling density and stability
- Conclusion: The Vacuum Degasser completes the process by removing small remaining gases, ensuring the mud remains stable and safe for use
Both work sequentially within the solids control system to maintain the safety of Oil and Gas Drilling Operations.
