摘要
The invention is a method, a system, tools for use by the system, and an interpretation method for injecting and detecting tracers and conducting flow characterizing of a petroleum well. The method describes monitoring of travel time and slip velocity between two/three different phases (oil/water and possibly gas) in the well. The travel time and slip velocity are determined using an injection tool for injection of an over pressurized injection, thus simultaneous injection to all phases, of the partitioning tracers each of which would follow certain phase. The tracers are detected by a tracer detector downstream the injector. The slip velocity is obtained from the difference of travel time of two tracers which partition to two different phases.
