Carbon/Oxygen logging technology is suited to a variety of conditions, and particularly for reservoir rocks containing fresh, brackish or unknown formation water salinities, i.e., conditions not suited to normal macroscopic cross-section measuring devices. The new-generation Multiparameter Spectroscopy Instrument Carbon/Oxygen Log (MSI C/O Log) began commercial service in Canada in early 1984, and represents a major advance in induced gamma ray spectroscopy logging technology.
