Abstract

Gamma emitter and detector are in the region of the boundary between the heavy oil close to the roof of the cavity and the brine formed by flushing the cavity out. The radiation emission shows an edge or break or else a sudden jump level with this boundary surface or interface between the liquids. The interface is then moved and by following the radiation peak it is possible to pinpoint the exact location of the interface. The marker isotope is pref. 82Br35, 131I53, 113Sn50 or 113In49.
