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.

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.
