Oil that appears on logs as fresh water—low-resistivity pay—has dogged geoscientists since the dawn of logging. With low oil prices driving the reexploration of mature fields, methods of interpreting low-resistivity pay have proliferated. We examine the causes of low-resistivity pay in sands and then explore the tools and techniques that have been developed to evaluate such frequently bypassed zones. A case study shows how log/core integration helps establish the source of low-resistivity pay in India's Gandhar field.
