A method for a rapid verification of clean-up at the end of the completion process while the completion rig is still at the well location comprising: marking one or more of separated zones along the well by one or more distinct tracers before starting the production, the tracers are added along with the completion, wherein the tracers are oleophilic and optical detectable, the tracers are arranged for to be released from every each zone to an inflowing fluid of oil or gas, collecting at least one sample of the produced petroleum fluid, processing the sample to change the tracers into non oleophilic (oleophobic) tracers, separate the non oleophilic tracers from the oil in the sample, optical inspection of the non oleophilic tracers, to verify if inflow of petroleum fluids in the tracer marked separated zones, takes place or not. |
