Question

Given below are two statements:
Statement (I): Well logging consists of recording the characteristic properties of the samples of sub surface materials obtained during the progress of test drilling.
Statement (II): Geophysical methods provide indirect evidence of the sub surface formations that indicates whether the formations may possibly be aquifers.
In light of the above statements, choose the most appropriate answer from the options given below:

• A. Both Statement (I) and Statement (II) are correct.
• B. Both Statement (I) and Statement (II) are incorrect.
• C. Statement (I) is correct but Statement (II) is incorrect.
• D. Statement (I) is incorrect but Statement (II) is correct.

Hint:

Electrical resistivity well logging is widely used because freshwater-bearing sand formations have high resistivity, whereas clay formations or saltwater-bearing sands have very low resistivity.

Answer 1

The Correct Option is A
