Petroleum Production Operations Multiple Choice Questions on “Subsurface Control Equipment”.

1. What is Catastrophe System?
a) Well Completion technique
b) Artificial lift technique
c) Pressure Gauge system
d) Down-hole shut-in system
View Answer

Answer: d
Clarification: Catastrophe System is a downhole shut-in system used at the time of imminent disaster. This system consists of a near-surface packer or hanger and master valve. This downhole valve can be self-controlled or remote controlled.

2. Surface Safety System is the protection system against mishaps in surface facilities.
a) True
b) False
Answer: a
Clarification: The statement is true. Surface Safety System is a type of first-line protection against minor mishaps in surface facilities. It consists of valves, piston, and spring assembly. For any type of uncontrolled gas bleed off the valve is closed by the action of piston and springs.

3. What is the full form of PRV in well completion?
a) Pressure Release Valve
b) Project Running Value
c) Pressure Relief Valve
d) Pressure Release Value
View Answer

Answer: c
Clarification: The full form of PRV in well completion is Pressure Relief Valve. Pressure Relief Valve is mainly used to control the pressure in a system; otherwise, the build-up pressure can damage the system.

4. Bridge plug is only used to shut-in the entire well.
a) True
b) False
View Answer

Answer: b
Clarification: The statement is wrong. A bridge plug is a downhole tool. It is used to plug the bottom hole from production. It may be a permanent or retrievable type. It may be used to isolate the bottom of the hole from the activities of the upper part of the well.

5. The full form of SCSV in petroleum production is _____
a) Subsurface controlled security valve
b) Subsurface controlled safety valve
c) Surface controlled security valve
d) Surface controlled safety valve
Answer: d
Clarification: The Cloud workloads use a distributed architecture. Failover and scaling are built into the application and it can scale out by adding more instances to meet the demand.

6. The full form of SSS in petroleum production is _____
a) Safety Surface System
b) Surface Safety System
c) Safety System on Surface
d) Safety System on Subsurface
View Answer

Answer: b
Clarification: The full form of SSS in petroleum production is Surface Safety System. It is the first line protection against any kind of fault in surface treating facilities. SSS consists of valves, piston, and spring assembly which come into action for any kind of uncontrolled gas bleed off the valve is closed by the action of piston and springs.

7. What is the Bottom hole regulator in well completions?
a) Reheat the flow stream
b) Allows Hydrate formation
c) Used to set the packer at the desired depth
d) Used to lower the Bottom Hole Flowing Pressure
Answer: a
Clarification: The bottom hole regulator is a device used in well completions that eliminated the freezing of the surface control and flowing lines. It eliminates the flowing problems caused due to hydrate formation.
