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: 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 are disclosed. 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 too for injection of an over pressurized injection of the partitioning tracers each of which would follow certain phase. The tracers are detected by an optical detection probe in the pipe. The slip velocity is obtained from the difference of travel time of two tracers which partition to two different phases.

Abstract: A method and a system for tracer marking and monitoring of a petroleum well with one or more production zones includes placing tracers at desired zones in a petroleum well with a production tubing, a casing or a liner with perforations at the zones and including lowering one or more patch-tubes into the well to a desired depth in a way that the one or more patch-tubes extends into the production tubing along on or more of the zones wherein the patch is divided in one or more patch zones along the patch, each patch zone includes one or more tracer sources with one or more unique tracers arranged to release to produced fluids, in desired positions, one or more radial expandable patch portions arranged to be expanded, upon desire, to seal against the tubing, anchoring an anchor of the patch to the tubing, allowing the well to produce well fluids and monitoring the production flow with respect to tracers.

CPC classification number: E21B47/11 , E21B34/066 , E21B34/08
Abstract: The invention provides a method of monitoring influx of a fluid to a hydrocarbon producing well comprising providing at least one tracer release apparatus (100) in a hydrocarbon producing well at an influx location (14a-14d). The at least one tracer release apparatus comprises a fluid volume (121) and a tracer material (124) located in the fluid volume. The method comprises shutting in the tracer release apparatus during production to increase the concentration of tracer molecules in the fluid volume; releasing the tracer molecules from the tracer release apparatus into the production flow and detecting the presence of tracer downstream of the influx location.
