Question 1
What of these is not a slugging type?
Correct option: A. Hydrodynamic
Types of slugging include:
- Terrain slugging
- Graining slugging
- Pigging slugging
Hydrodynamic is not a type of slugging.

Question 2
When two or more phases exist in the production fluid such as such as oil, gas, water, and sand, we term that as a ______
Correct Answer: B. Multiphase flow
When the production fluid contains two or more phases—such as oil, gas, water, and sometimes sand—it is referred to as multiphase flow, a common phenomenon in petroleum production systems.

Question 3
One problem that can occur by slugging is that it_____________?
Correct Answer: A. Can make deposit and cause corrosion
Slugging causes intermittent flow of gas and liquid phases, which can lead to liquid accumulation, uneven flow, and eventually deposits and corrosion in pipelines and equipment.
Not clear enough?
Question 4
Two of these are causes of slugging?
Correct Answer: A. Low gas-oil ratio / High Water Cut
Slugging is often caused by a low gas-oil ratio, which reduces the ability of gas to keep liquids moving, and a high water cut, which contributes to unstable flow regimes—both conditions favor the formation of liquid slugs.

Question 5
Which of these controls flow rate
Correct Answer: A. Rotator
A rotator controls flow rate by regulating rotational speed in certain pumping or mechanical flow systems.

Question 6
Gas lift is Not applied to?
Correct Answer: D. Pump
Gas lift is an artificial lift method used to improve production by injecting gas into the wellbore, often through the tree or at the riser base. However, it is not applied to a pump, as gas lift is an alternative to mechanical pumping systems.

Question 7
One of these four flow regimes is Not necessary to worry about when dealing with erosion during production?
Correct Answer: D. Huston bed flow
"Huston bed flow" is not a recognized flow regime in multiphase flow dynamics. The known flow regimes include homogeneous, heterogeneous, stratified, slug, annular, and bubbly flow, among others. So, there's no need to worry about "Huston bed flow"—it doesn’t exist.
Not clear enough?
Question 8
When is sand flow most difficult?
Correct Answer: A. When sand flow is going uphill
Sand flow is most difficult when going uphill because gravity opposes the movement of solid particles. This increases the risk of sand accumulation, blockages, and erosion, especially in inclined or vertical sections of the wellbore or pipeline.
Not clear enough?
Question 9
The mechanical process of wearing or grinding something down
Correct Answer: A. Erosion
Erosion is the mechanical process of wearing or grinding something down, often caused by the movement of solid particles (like sand) within a fluid stream. It leads to the gradual loss of material from surfaces, especially in pipelines and equipment during production.

Question 10
What does SPPS stand for?
Correct Answer: A. Sand Production Pipe Saver
SPPS stands for Sand Production Pipe Saver, a term typically used to describe tools or systems designed to protect pipelines and equipment from damage caused by sand production during oil and gas extraction.
