摘要： A tracer-embedded degradable article includes: a degradable metallic carrier; and a tracer disposed in the degradable metallic carrier, wherein the tracer includes an upconverting particle that has a host material, and a dopant. The article is manufactured by forming a mixture containing the metallic carrier and the tracer; and molding or casting the mixture. The degradation of the article is monitored by disposing the article downhole; degrading the article; releasing the tracer from the article to a wellbore fluid; and analyzing the wellbore fluid to determine an amount of the tracer in the wellbore fluid.

摘要： A method of using a tracer additive in a wellbore that includes using a perforator device, the perforator device having an at least one shaped charge associated with the tracer additive. The method includes deploying the perforator device into the wellbore in manner whereby the perforator device arrives at a desired location, and sufficiently detonating an explosive material of the shaped charge so that the tracer additive comes into contact with a target formation. The tracer additive has a first composition, and is in powder form.

摘要： A method includes developing a lab-scale representative correlation between wettability index and tracer test return curve data for core samples, obtaining tracer test return curve data for rock at a well of interest, and determining a wettability index of the rock in situ using the representative correlation and the tracer test return curve data for the well. A method includes obtaining core samples of a rock representative of a formation of interest, determining a wettability index of each of the core samples, performing a tracer test on each of the core samples and obtaining tracer return curve data for each of the core samples, building a correlation between the wettability index and the tracer return curve data of the core samples, running a single-well tracer test at a well, obtaining tracer return curve data for the well, and determining a wettability index for the rock of the well.

摘要： A method for evaluating induced fractures in a wellbore includes obtaining a first set of data in a wellbore using a downhole tool. The method also includes pumping a first proppant into the wellbore after the first set of data is obtained. The first proppant includes a first tracer that is not radioactive. The method also includes pumping a second proppant into the wellbore. The second proppant includes a second tracer that is not radioactive. The second tracer is different than the first tracer. The first proppant and the second proppant flow into fractures in the wellbore. The method also includes obtaining a second set of data in the wellbore using the downhole tool after the first and second proppants are pumped into the wellbore. The method also includes comparing the first and second sets of data.

摘要： A method includes introducing a fluoro-based small molecule tracer into a stimulation fluid, injecting the stimulation fluid into a target zone of a subterranean formation, and maintaining the fluoro-based small molecule tracer inside the target zone of the subterranean formation for an amount of time. While being maintained inside the target zone, the fluoro-based small molecule tracer comes into contact with water at a downhole temperature resulting in hydrolysis of the fluoro-based small molecule tracer to produce a fluorinated tracer and a nonfluorinated group. Then, produced fluid that includes the fluorinated tracer is recovered, a concentration of the fluorinated tracer in the hydrocarbons is determined, and the concentration of the fluorinated tracer is correlated to a productivity of the target zone of the subterranean formation.

摘要： A method for monitoring gas production in a subterranean formation includes introducing a polymer composite particle having a degradable portion and a non-degradable portion including a tracer into a stimulation fluid and injecting the stimulation fluid into the subterranean formation to a treatment stage of a treatment zone. The treatment stage has at least one opening that the polymer composite particle may flow into and remain inside. The polymer composite particle may be exposed to moisture at a downhole temperature while inside the at least one opening. The moisture may degrade the degradable portion of the polymer composite particle, thereby releasing the non-degradable portion including the tracer. Produced gas that includes the non-degradable portion including the tracer may be recovered from the subterranean formation and the tracer may be correlated to the treatment stage of the treatment zone of the subterranean formation.

摘要： A method for quantitative downhole surveillance of a multi-phase flow, comprising at least two phases of either oil, water or gas, in a petroleum well. The method comprising providing at least one shunt chamber (100) which comprises a flow phase separation section (130), a delay chamber (140), one or more outlet ports (122), at least one flow restrictor (126a, 128b) and a tracer release system (124) with one or more tracers. The method comprises separating a shunt flow in the shunt chamber into a low-density flow phase and a high-density flow phase; releasing at least one tracer into the tracer delay chamber, passing the separated flow phases through each flow restrictor and flushing out the phase flows with tracer into the local flow inside the well. The method comprises monitoring the tracers in the production flow and measuring the concentration of the one or more tracers.

摘要： A method for mapping inter-well porosity includes injecting a Type 1 tracer into a hydrocarbon-bearing reservoir via an injector well, wherein the Type 1 tracer is a passive tracer, injecting a Type 2 tracer into the hydrocarbon-bearing reservoir via the injector well, wherein the Type 2 tracer is a porosity-sensitive tracer, detecting a breakthrough of the Type 1 tracer and a breakthrough of the Type 2 tracer in produced fluid at a producer well, and comparing the breakthrough of the Type 1 tracer with the breakthrough of the Type 2 tracer to provide a map of inter-well porosity.

摘要： A valve assembly for integration within a wellbore string disposed within a hydrocarbon-containing reservoir is provided. The valve assembly includes a valve housing having a plurality of frac ports for establishing fluid communication between a central passage and the reservoir. The valve assembly includes a bottom sleeve operatively mounted within the valve housing configured to selectively open the frac ports, and a top sleeve operatively mounted within the valve housing slidable between (i) a first position defining a first fluid pathway whereby fluid is flowable down into the central passage and into the reservoir via the frac ports, and (ii) a tracing position defining a second fluid pathway whereby fluid is flowable from the reservoir into an annulus defined between the top sleeve and the housing. The valve assembly also has a tracer compartment defined within the annulus forming part of the second fluid pathway and accommodating a tracer material.
