What is petrophysics?

In petroleum exploration, the geological model is developed and then proved, disproved, or modified by drilling. The subsequent commercial decisions are based on the existence and mobility of hydrocarbons within the pores of the reservoir rock under downhole conditions.

When a hydrocarbon-bearing formation is cored, the properties of the fluid contained in the pores changes as the core is brought to surface. Most of the more volatile components leak away during the decompression process and during surface handling.

Hence wireline logging, was developed. In order to understand the geological significance of . . .
