The use of a formation's dielectric constant log to delineate hydrocarbon zones complements the use of electrical resistivity (conductivity) based on logging systems, particularly where the formation-water salinity is low and variable. A review of the physical principle of the dielectric log describes the current status of commercial dielectric-constant logging systems and points out the previous and potential areas of application for such logs. Although the present systems cannot yet make quantitative measurements of water saturation, the integration of dielectric methods into ongoing logging programs could increase the chances of finding hydrocarbons by 10-30% in formations having variable and high (>10 ohm-meters) electrical resistivities (due to variable, low water-salinity changes). For an equivalent cost, the dielectric-constant logging system can evaluate more formations than conventional methods.
