MULTIPURPOSE LOGGING EQUIPMENT FOR URANIUM EXPLORATION AND EVALUATION OF DEPOSITS
Logging metods which have thown great promise are single-point electric logging (wet or dry), combined electric and gmma-ray logging, multielectrode resistivity logging, and caliper logging. An extended applicaiion of the single- point electric logging method has been developed. The new technique involves quantithtive interpretation of the resistance log for either wet or dry holes by the use of departure curves. The theory, field techniques, equipment and operationaly costs, and application of this logging method are discussd. The combination logging of gamma-ray radiation and formation resistance simultaneously on a two-channel logger offers the unique advantage of direct comparison of lithology and mineralization. Equipment costs, probe specifications, operational techniques and applicability of combination logging are discussed. An experimental dry-hole probe with four pairs of vertically offset roller electrodes thens beeen used to evaluate the multiple electrode dry- hole resistivity logging method. The theory, purpose, equipment, operational techniques, interpretation of results as costs are discussed. Caliper logging involves measuring the diameter of a drill hole versus depth. Examples of caliper logs are shown. (auth)
