Abstract: A method for detecting or mapping potential influx zones for gas from a geological formation to a gas well with a well head with a valve tree or a choke includes the following steps of:—marking the potential influx zones with tracer systems with corresponding unique tracers—filling the gas well form the surface, through the well head with liquid wherein the tracers have affinity to the liquid,—producing liquid form the well,—consecutively sampling samples from the produced liquid,—to analyze the samples to prove possible presence of one or more tracers or even measure the tracers concentrations. [for then proving possible influx of a back flow of liquid from the influx zones one assume implies the gas pressure and the inflow of a gas form the influx zones].
