Abstract: The invention provides a method for quantitative downhole surveillance of a multi-phase flow, comprising at least two phases of either oil, water or gas, in a petroleum well. The method comprising providing at least one shunt chamber which comprises a flow phase separation section, a delay chamber, one or more outlet ports, at least one flow restrictor and a tracer release system with one or more tracers. The method comprises separating a shunt flow in the shunt chamber into a low-density flow phase and a high-density flow phase; releasing at least one tracer into the tracer delay chamber. The method also comprises passing the separated low-density flow phase and high-density flow phase through each flow restrictor and flushing out the low-density phase flow and the high-density phase flow with tracer from the shunt chamber through the outlet ports into the local flow inside the well. The method comprises monitoring the at least one tracer in the production flow at a detection point downstream of the outlet ports and measuring the concentration of the one or more tracers in the monitored.
