This set of Petroleum Production Operations Multiple Choice Questions & Answers (MCQs) focuses on “Sand Control – Resin Consolidation Methods”.
1. Thicker gravel packs permit higher production rates.
a) True
b) False
View Answer
Explanation: The statement is true. Thicker gravel packs permit higher production rates. Well’s productivity is measured by the productivity index. But formation sand must be stopped at the outer edge of the gravel pack.
2. What is Resin injection used in the oil and gas industry?
a) Consolidation of sand
b) Consolidation of packer
c) Consolidation of Annulus
d) EOR Method
View Answer
Explanation: Resin consolidation method is one of the type of sand consolidation method in the loose sand formation where the sand production problems have occurred. It consolidates the formation sand grains.
3. The viscosity of the resin in the resin consolidation should not be_____
a) Minimum
b) Moderate
c) Low
d) Excessive
View Answer
Explanation: Viscosity of resin should not be excessive. Resin injection is simply considered as artificial consolidation of sand. Plastic resins are injected into the formation sand grains that help in consolidating the formation sands.
4. Why the pre-flush is required in resin consolidation?
a) Remove oil
b) Remove gas
c) Remove undesired material
d) To remove the packer
View Answer
Explanation: Pre-flush is required in resin consolidation. The formation wall wettability is also get affected by the pre-flush and ultimately it helps in removing the materials which are not our area of interest.
5. Which of the following is the advantage of Resin consolidation?
a) Limited Longevity
b) The sensitivity of Temperature <250°F
c) Leaves wellbore open
d) Reduces permeability by 10%-60%
View Answer
Explanation: The advantages of Resin consolidation are Leaves wellbore open, Low cost, screens, and liners are not needed. The disadvantages are Limited Longevity, Sensitivity of Temperature <250°F, Reduces permeability by 10%-60%.
