This set of Petroleum Production Operations MCQs focuses on “Special Squeeze Cementing Situations”.
1. Which of the following is used to push the cement down the well?
a) Packer
b) Top Drive
c) Plug
d) Coiled tubing
View Answer
Explanation: Plug is used to push the cement down the well. Basically, plugs are made with rubber material. It is used to differentiate or for reduction purpose of the contamination of the wellbore fluid and the cement slurry.
2. What can snubbing do, that Coil Tubing can’t?
a) Faster drilling
b) Rotate
c) Faster production
d) Packer disintegration
View Answer
Explanation: For rotation purpose the petroleum engineers uses the Snubbing unit as the coiled tubing unit is of no use for this purpose. Bottom hole assemblies are also run down the well in the case of snubbing operation.
3. Slickline has no electrical conductor.
a) True
b) False
View Answer
Explanation: The statement is true. Slickline has no electrical conductor. Slickline refers to a single strand wire which is used to run tools into the wellbore for several purposes. It is used to deliver and retrieve tools downhole.
4. In which of the following case workover rig or mobile rig is not used?
a) Drilling
b) Pulling tubing
c) CO2 flooding
d) Cement jobs
View Answer
Explanation: For CO2 flooding workover rig or mobile rig is not used. gas-injection EOR projects in operation today use CO2 as the injected gas. It is an enhanced oil recovery (EOR) method in which carbon dioxide (CO2) is injected into a reservoir to increase production by reducing oil viscosity and providing a miscible or partially miscible displacement of the oil in oil and gas upstream industry.
5. What is the most common use of Coiled tubing?
a) Cement jobs
b) Intervention and completion
c) Running casing
d) Fracturing
View Answer
Explanation: The most common use of Coiled tubing is at the time of Intervention and completion. Coiled tubing refers to a very long metal pipe that is continuous in nature without any joint, normally 1 to 3.25 in diameter which is supplied spooled on a large reel.
