Abstract

Because of the very low count rates associated with gamma-ray core logging, core gamma data generally exhibit a considerable amount of statistical variation. With older analogue recording equipment, long time-constants were used to minimize the statistical variation in count rate; however the adoption of a long time-constant requires that the logging speed be chosen to suit the required spatial resolution. With the digital recording technique used in this new core logging system, the time-constant is kept to a minimum and statistical variation reduced by subsequent filtering of the raw data.
