Description

Calcium carbonate scale formation during flow in porous media was studied using radioactive tracer technology; in a series of calcite scaling experiments in sandpacks, 47 Ca was used as a tracer to monitor CaCO3 deposition. In these experiments, the induction time and the distribution of scale deposition were studied as a function of saturation ratio, temperature, flow velocity, the presence of Mg ions, and the type of packing material. The results show that the radiotracer method gives a fast response to scaling events. The technique is applicable for dynamic scaling investigations in any flowing system in porous media and constitutes a valuable tool for further studies of scaling mechanisms involved in processes occurring in a variety of systems (oilfield, geothermal, and desalination).
