Introduction and Value Proposition
Petrophysicists are often referred to as the link, or bridge, between the geosciences and engineering. A petrophysicist’s primary role is to derive/interpret formation rock and fluid properties from the open hole, cased hole wireline, or
production logging data in a wellbore to estimate the existing amount of hydrocarbon in place. The discipline requires several facets that span the Exploration andProduction (E&P) life cycle and can support real-time operational efforts, contributing to regional or development scale studies, and any mapping or modeling requirements (Figure 1).
