# Petroleum Production Operations Questions and Answers – Application of Through Tubing Production Logging

This set of Petroleum Production Operations Interview Questions and Answers for freshers focuses on “Application of Through Tubing Production Logging”.

1. Noise logging tool can be used to find out tubing casing leaks.
a) True
b) False

Explanation: The statement is true. Noise logging tool can be used to find out tubing casing leaks. Noise logging tool includes noise sensor-transducer which converts noise signal to electrical signal to find out the tubing casing leaks.

2. Which of the following is correct about the noise logging tools?
a) Can be used to find out the temperature
b) Can be used to find out the pressure
c) Can be used to find out the fluid type
d) Can be used to find out the fluid density

Explanation: Noise logging tools can be used to find out the type of fluid. The major uses of Noise logging tools are to find out the channels behind casing, perforation and tubing casing leaks. The type of fluid can also be detected with the help of Noise logging tools.

3. Inflatable Diverter flow meter can be used to measure the flow rate.
a) True
b) False

Explanation: The statement is true. Inflatable Diverter flow meter can be used to measure the flow rate. Inflatable Diverter flowmeter divert all the flow through the spinner. Restriction is created by using the packer.

4. If the correlation co-efficient is less than 1 then it indicates then the data obtained from the flow meter is of _____
b) Medium Quality
c) Good quality
d) Doesn’t depend on correlation coefficient

Explanation: If the correlation co-efficient is less than 1 then it indicates then the data obtained from the flow meter is of Good quality. That is why the FRQT calibration plot is required for obtaining a good quality data.

5. Which of the following type of logging tool can be run down during the time of perforation for depth correlation?
a) CCL log
b) Gamma Ray log
c) SP log
d) Resistivity log

Explanation: Casing Collar Locator log can be used for the purpose of depth correlation i.e. the depth at which the perforation has to be done during perforation. Gamma Ray log is used to find out the shaly and non-shaly formations, SP for porous and permeable formations and the Resistivity log is used to find out the hydrocarbon trap.
