This set of Petroleum Production Operations Multiple Choice Questions & Answers (MCQs) focuses on “Perforating Fluids and Packer Fluids”.
1. Water-based fluids are used as conventional packer fluids.
a) True
b) False
View Answer
Explanation: The statement is False. The corrected statement is Water-based fluids are not used as conventional packer fluids. Packer fluid must follow this criterion of giving protection from corrosion or embrittlement.
2. For the case when the high strength pipe is to be involved in completion. For any condition of temperature and fluid density which of the following fluid is recommended?
a) Oil Based Mud
b) Water Based Mud
c) Perforating Mud
d) Foam
View Answer
Explanation: Properly formulated Oil Based Mud or Invert Emulsion Muds are recommended when the high strength pipe is to be involved in completion for any condition of temperature and fluid density.
3. Consider the case when there is no high strength pipe involved in completion, Packer fluid density of greater than 11.5 ppg is required and the Bottom hole temperature exceeds 300 deg F, which of the following fluid is recommended?
a) Foam
b) Water Based Mud
c) Perforating Mud
d) Oil Based Mud
View Answer
Explanation: Properly formulated Oil Based Mud can be used when there is no high strength pipe involved in completion, Packer fluid density of greater than 11.5 ppg is required and the Bottom hole temperature exceeds 300 deg F.
4. Consider the case when there is no high strength pipe involved in completion. Packer fluid density of less than 11.5 ppg is required which of the following fluid is recommended?
a) Foam
b) Water Based Mud
c) Diesel Oil
d) Oil Based Mud
View Answer
Explanation: Diesel oil or Sweet crude can be used when there is no high strength pipe involved in completion. Packer fluid density of less than 11.5 ppg is required. They should be used with an inhibitor if the fluid density permits.
5. Which of the following is an excellent perforating fluid?
a) Saltwater
b) Foam
c) Invert Emulsion Mud
d) Acetic Acid
View Answer
Explanation: Acetic Acid is an example of excellent perforating fluid. Perforating fluid is a specially designed fluid to be used at the time of perforation of a well in oil and gas upstream Industry.
