Abstract

An improved radioactivity well logging sonde for sensing fluid flow in an earthen formation from a borehole traversing the formation in which the borehole also contains salt water includes a neutron source for irradiating the earthen formation with neutrons and a detector assembly which detects gamma radiation from the earth formation. The sonde also includes circuitry which processes pulses from the detector assembly to be provided uphole by way of a well logging cable. The sonde includes apparatus spatially arranged with the detector assembly which displaces salt water in the borehole so that there is substantially no salt water between the side of the borehole and the detector assembly. The improved well logging sonde also permits vertical fluid flow measurements in an earthen formation as well as the conventional horizontal fluid flow.
