Abstract: A method of estimating an influx profile for at least one well fluid to a producing petroleum well with two or more influx zones or influx locations to a production flow, wherein the well comprises tracer sources with distinct tracer materials in known levels of the well, at least one of said tracer sources arranged downstream and exposed to the fluids in at least one of said influx zones, wherein each said tracer source has an even release rate to said well fluid, characterised in that one or more of the tracer sources is provided in one or more delay chambers for ventilating out fluid with leaked tracer material at a time constant which is significantly longer than the diffusion rate from the tracer source to the well fluid, wherein the method further comprises: providing samples, the samples collected from the production flow at a location downstream of the tracer sources during a time period in which the tracer transient is detectable at the downstream location, analysing said samples for concentration and type of tracer material from said possible tracer sources as a function of sampling time or cumulative produced volume; and based on said measured concentrations and their sampling time or cumulative produced volume, calculating said influx volumes.

Abstract: 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.

Abstract: A petroleum well formation pressure meter system includes a petroleum fluid conducting tubing in a borehole through a reservoir rock formation. The tubing includes a blank pipe section forming a blank-pipe-isolated first annulus section isolated by a first and a second packer and an adjacent non-blank pipe section beyond said first packer forming a tubing-communicating petroleum producing second annulus section. The first packer includes a tracer-conducting channel allowing through passage of tracer material from an inlet from a bellows including a fluid tracer in pressure communication with said blank-pipe-isolated annulus section, to an outlet to said tubing-communicating annulus section.

Abstract: A method and system estimates an influx profile for at least one well fluid from a reservoir to a producing petroleum well with two or more influx zones or influx locations to a production flow. The method includes installing at least one tracer source with distinct tracer materials in known levels of the well and transporting tracer molecules from the tracer sources in the well into the reservoir. The method also includes inducing production flow in the well from the reservoir into the well, collecting samples downstream of the two or more influx zones at known sampling times and analyzing samples for concentration and type of tracer material from said possible tracer sources. The contribution of flow from the two or more influx zones may be calculated based on the analyzed tracer concentrations.
