This set of Petroleum Production Operations Multiple Choice Questions & Answers (MCQs) focuses on “Oil Fluids – Practical Application”.
1. What type of Workover fluid can be used for sand consolidation purposes?
a) Formation fluid
b) Diesel Oil
c) Brine Water
d) Seawater
View Answer
Explanation: Diesel Oil can be used as a workover fluid for sand consolidation purposes. This fluid is used where especially a clean fluid is required. A workover fluid is a fluid which is placed against the producing interval to control the formation pressure during workover operations
2. Oil is not a good packer fluid.
a) True
b) False
View Answer
Explanation: The statement is False. Oil is an excellent packer fluid under workover operations. It is excellent from the standpoint view of minimizing corrosion. Also, gel strength can be provided to limit the solids setting.
3. To check the solids content in crude what type of tests can be done?
a) SPE test equipment
b) AAPG test equipment
c) MSME test equipment
d) API fluid loss test equipment
View Answer
Explanation: API fluid loss test equipment can be used to test the amount of solids content in crude in the field. It can be measured using the American Petroleum Institute test apparatus and by following their procedures.
4. In low-pressure formations, Oil as a workover fluid can be used.
a) True
b) False
View Answer
Explanation: The statement is true. The crude oil obtained from the Stock tank is weathered enough to reduce the fire hazard. Crude oils should always be checked for the presence of asphaltenes and paraffin.
5. Which of the following mentioned parameters does not affect the Vertical lift performance or tubing performance?
a) Tubing size
b) Perforations
c) Tubing wellhead flowing pressure
d) Reservoir fluid properties
View Answer
Explanation: The Perforations does not affect the Vertical lift performance or tubing performance. Tubing size, Tubing wellhead flowing pressure, Reservoir fluid properties affect the VLP. TPR and IPR are plotted on the same graph to get the optimum production rate for a particular size of tubing.
