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. The present application provides a laminator table, wherein the table comprises a table top (8) with two opposite and parallel side edges (7), a horizontal guide rail (6) parallel to and at each of said side edges, and a roller (2) arranged above the table top, each horizontal guide rail (6) comprises a raising/lowering device (1) having a first and a second end, the first end connected to one of the two ends of the roller (2), the second end is connected to the horizontal guide rail (6), the raising/lowering device (1) is horizontally moveable along the guide rail (6) to which it is connected, wherein each raising/lowering device (1) comprises at least an attachment (4) for a wire (3), belt or chain, and that the raising/lowering devices (1) are connected via one or several wires (3,3'), belts or chains connected to said attachments (4) by a system of pulleys (5) or gears, wherein the pulleys (5) or gearsare situated such that the wire (3,3'), belt or chain, at movement in a horizontal direction of a first raising/lowering device (1), will transfer force from said first raising/lowering device (1) to the second raising/lowering device and pull this second raising/lowering device in the same horizontal direction as the first.
