Abstract
A method and apparatus for studying the flow of water along a well, on the basis of a general spectrum g(t) of gamma ray detection numbers detected in a detection zone over a given detection duration and as a function of time, said gamma rays resulting from the activation of oxygen atoms in water by neutrons emitted by a source to create an activation reaction O.sup.16 (n,p)N.sup.16.
