Abstract
Formation fluid is activated by a neutron source. A cluster of three gamma ray detectors provides count rate data with the count values varying among the three detectors as dictated by the geometry of the cluster and the angle of displacement of the activated fluid between the time of neutron bombardment and that of gamma ray detection. Measurements at different time intervals following the activation of the fluid may also be interpreted in terms of the speed of horizontal fluid flow past the borehole.
