Show Hint
Well log: Geological record of borehole strata.
Used for: Determining casing depth, screen placement, aquifer identification.
Casing: Protects well from collapse, prevents contamination.
Screens: Allow water entry while keeping sand out.

- Both Statement I and Statement II are correct
- Both Statement I and Statement II are incorrect
- Statement I is correct but Statement II is incorrect
- Statement I is incorrect but Statement II is correct
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept:
This question tests knowledge of well construction and well logging.
Step 2: Detailed Explanation:
Statement I:
Well casings and screens are installed based on the well log (borehole log).
The well log provides information about the geological formations encountered during drilling.
This helps determine the depth of casing and the location of screens.
This statement is true.
Statement II:
Well log is a systematic record of geological formations (strata) encountered during drilling.
It includes information on depth, type of soil/rock, color, texture, etc.
It is not just a record of length of screens and casings.
This statement is false.
Step 3: Final Answer:
Thus, Statement I is correct but Statement II is incorrect.
