An overview of water- and emulsion-based wells killing and washing fluids, developed in Gubkin Russian State University of Oil and Gas, is given. The possibility of using the modern brine plant facilities of the FSI International Services Ltd. manufacturing for qualitative process fluids production is shown. A comprehensive solution to the problem of wells killing with low-impact killing fluids and special equipment for their preparation will allow to eliminate the problems associated with trouble-free maintenance work execution and will preserve the recovery wells productivity.
