This set of Petroleum Production Operations Multiple Choice Questions & Answers (MCQs) focuses on “Introduction to Sand Control”.
1. What is Sand control?
a) Method to minimize the sand production
b) Method to increase the sand and fine production
c) Method to minimize gas production
d) Method to minimize the oil production
View Answer
Explanation: Sand control is the Method to minimize sand production. Sand and fine produced along with the oil and gas can cause erosion and at the same time, it can wear of production facilities or equipment. So ultimately there will be a downfall of production.
2. In defining the sand control, we don’t mean the control of the load bearing solids.
a) True
b) False
View Answer
Explanation: The statement is false. The corrected statement is in defining the sand control; we mean the control of the load bearing solids. We’ve to differentiate between the load bearing solids and fine solids associated with the formation fluids.
3. What is the Critical Flow rate in the context of sand control?
a) Maximum allowable flow rate below which sand is produced
b) A minimum allowable flow rate that doesn’t produce sand
c) A maximum allowable flow rate that doesn’t produce sand
d) Minimum allowable flow rate below which sand is produced
View Answer
Explanation: Critical Flow rate in the context of sand control is the maximum allowable flow rate that doesn’t produce sand. In the petroleum industry, it is very much required to limit the production rate below the critical flow rate to avoid sand production.
4. Drag forces of the flowing fluid _____ with higher flow rates and higher viscosity.
a) Increases
b) Decreases
c) Remains constant
d) Are independent
View Answer
Explanation: Drag forces of the flowing fluid increases with higher flow rates and higher viscosity. Sand grains are stabilized by overburden weights of the layers above which act as compressive forces. The drag force is basically acting on the principle of friction.
5. Declining in reservoir pressure may disturb the cementation between the grains.
a) True
b) False
View Answer
Explanation: The statement is true. Declining in reservoir pressure may disturb the cementation between the grains. Actually. Declining in reservoir pressure increases the compaction forces that ultimately affects the stability of the grains.
