Pulsed Neutron Devices and Spectroscopy, distinguishing saline formations waters from hydrocarbons. Chlorine, which is nearly always present in formation waters, has a large absorption cross section. Measurement of the macroscopic absorption cross section (∑) can provide the means for identifying salt water and for estimating the water saturation.

Nuclear Magnetic Logging,oped by Chevron in 1960. NMR, with its multitude of medical applications and visual diagnostic tools, enabled by ubiquitous high-powered computers and graphics algorithms, made its way into every day conversation – in a politically-correct version – as magnetic resonance imaging.

Introduction to Well Log Interpretation: Finding the Hydrocarbon,to the extraction of quantitative petrophysical parameters from the logging measurements. This extraction process is the subject of subsequent chapters. Once these relationships are established, more quantitative procedures of interpretation will be described.
