This set of Petroleum Production Operations Multiple Choice Questions & Answers (MCQs) focuses on “Squeeze Cementing – Normal Operational Procedure”.
1. Squeeze packers are used for low-pressure squeeze cementing.
a) True
b) False
View Answer
Explanation: The statement is true. Squeeze packers are specially designed to be used for low-pressure squeeze cementing. Those zones where pressures are anticipated along with other perforations then squeeze tools are used.
2. When is the retrievable squeeze packers used?
a) Resetting permits flexibility and to find casing leak
b) Low-pressure application
c) High-pressure application
d) At the time of Drilling
View Answer
Explanation: A retrievable squeeze packer allows flexibility of the resetting and at the same time it can detect the casing leak. By using this squeeze cementing can be done very easily at the casing leak and less rig time is required for this purpose.
3. Why does coiled tubing have a faster rate of penetration than rotary drilling rig?
a) It doesn’t need a special crew
b) Since connection needs to be made
c) It is a continuous reel
d) It requires more joined pipes to connect with
View Answer
Explanation: Coiled tubing has a faster rate of penetration than rotary drilling rig because it is a continuous reel. So, very little time is required for the operations. Coiled tubing refers to a very long metal pipe that is continuous in nature without any joint.
4. The Cement Retainer is a drillable packer.
a) True
b) False
View Answer
Explanation: The statement is true. Drillable packers are also called Cement Retainers. Cement Retainers consistently contain well pressures at elevated temperatures and pressures. This packer is used in squeeze cementing purposes.
5. What is wait on cement?
a) The time required for cementing
b) The time required for casing placement
c) The time required for the cement to solidify
d) The time required for the cement to just place around the casing
View Answer
Explanation: Wait on cement is the time required for the cement slurry to solidify. By allowing the cement slurry sufficient time, the cement slurries develop compressive strength. Thus it allows further activities.
