What are the three main physical properties of rocks logged by wirelines?

The three main physical properties of rocks logged by wirelines are electrical, nuclear, and acoustic. Each of these properties provides valuable information about the subsurface geology and the characteristics of the rocks being examined.

Electrical properties involve measuring the resistivity of rocks, which helps in identifying fluid content and rock types. Different rocks and fluids have distinct resistivity values, aiding in the interpretation of the geological environment.

Nuclear logging typically centers on the interaction of gamma rays with the rocks. This method can yield information about the mineral composition and porosity of the formations through the detection of natural radioactive isotopes or the measurement of induced radiation.

Acoustic properties focus on the speed of sound waves traveling through the rocks. By analyzing how these waves behave, it is possible to infer mechanical properties such as porosity and elastic moduli, which correlate with the rock's ability to store and transmit fluids.

The other options involve properties that may relate to the study of geology but do not encompass the three primary properties traditionally logged by wirelines. Understanding these fundamental properties is crucial for interpreting subsurface conditions and making informed decisions in exploration and production in geology.
