Abstract

A method and system has been disclosed for determining a position of a water/cement boundary in an annular area between two concentric pipes in a hydrocarbon well. The method comprises the steps of running a well tool (10) into a central pipe of the well, where the well tool (10) comprises a tool housing (11), at least a first and a second pulse generators (14, 34) and at least one signal recorder (16, 17, 18) provided within the housing (11), generating a first and second electromagnetic pulses by means of the first and second pulse generators, respectively, the first and second pulses being separated by a time interval,thereby providing physical vibrations in the central pipe of the well; recording reflected acoustic signals from the well by means of the signal recorder (16); repeating the generating and recording steps with different time intervals of the pulse generators in the well; organizing the recorded signals in a two-dimensional representation; filtering the organized recorded signals in order to identify, in the two-dimensional representation, a hyperbola (B); and providing an apex of the hyperbola (B) as the determined position of the water/cement boundary.
