Abstract
The present invention is a well logging apparatus and method for measuring the azimuth and speed of horizontal flow by a borehole using a conventional well logging sonde having a neutron source for irradiating the earthen formation surrounding the borehole. A gamma ray detection assembly in the sonde includes a segmented crystal and a segmented photomultiplier tube optically coupled to said segmented crystal. An additional gamma ray detector is located within the sonde and is displaced longitudinally along the sonde's longitudinal axis from the gamma ray detection assembly.
