摘要： A composition and method for hydraulically fracturing an oil or gas well to improve the production rates and ultimate recovery using a porous ceramic proppant infused with a chemical treatment agent is provided. The chemical treatment agent may be a tracer material that provides diagnostic information about the production performance of a hydraulic fracture stimulation by the use of distinguishable both water soluble and hydrocarbon soluble tracers. The tracer can be a biological marker, such as DNA. The porous ceramic proppant can be coated with a polymer which provides for controlled release of the chemical treatment agent into a fracture or well bore area over a period of time.

The first end of the first conical section comprises a rounded nose. The second conical section comprises an outside surface tapering from a first end to a second end. The first end of the second conical section comprises a rounded nose. The second end of the first section can contact or be integrated with the second end of the second section, or an intermediate section can be positioned therebetween. The intermediate section can comprise a substantially cylindrical outer surface extending from the second end of the first conical section to the second end of the second conical section. The support legs are configured to fixedly couple the flow diverter to a tubular.

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 and a system for injecting multiple tracer tag fluids into the wellbore are described. The method includes determining multiple injection concentrations of multiple respective tracer tag fluids, determining an injection sequence of the tracer tag fluids into a wellbore, and injecting the tracer tag fluids into the wellbore according to the injection concentrations and the injection sequence. The tracer tag fluids include synthesized polymeric nanoparticles suspended in a solution. The synthesized polymeric nanoparticles are configured bind to a wellbore cutting. The synthesized polymeric nanoparticles are configured to undergo a thermal de-polymerization at a respective temperature and generate a unique mass spectra. The injection sequence includes an injection duration determined by a depth interval of the wellbore to be tagged by the synthesized polymeric nanoparticles and an injection pause to prevent mixing the multiple tracer tag fluids in the wellbore.

摘要： A system for testing of leaking past a well barrier. The system includes a well including a wellbore and a upper wellbore termination means. A barrier is provided in the wellbore, the barrier having an upstream side below the barrier and a downstream side above the barrier. The system further includes a tracer and a storage means for storing said tracer, the storage means being provided below the barrier in the well. A release mechanism is configured for releasing the tracer from the storage means, wherein a pressure differential is established across the barrier for driving tracer from the upstream side to the downstream side of the barrier. A detector is configured for detecting the tracer that has leaked through the barrier, the detector being provided in the wellbore between said barrier and said upper wellbore termination means.

摘要： The present disclosure is directed to methods for evaluating a gravel pack, a frac-pack, or cement in a wellbore. In at least one embodiment, a method for evaluating a gravel pack, frac-pack or cement in a wellbore, includes pumping a first material into the wellbore, wherein the first material comprises a first tracer that is not radioactive. The method includes pumping a second material into the wellbore, wherein the second material comprises a second tracer that is not radioactive. The method includes obtaining a set of data using the downhole tool in the wellbore after the first and second materials are pumped into the wellbore. The method includes obtaining a baseline using the downhole tool in the wellbore in a depth interval without the first or second material. The method includes comparing the set of data with the baseline.

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： Techniques for determining depths of provenance of drill cuttings contained in a drilling fluid received from a wellbore. The drilling fluid contains drill cuttings of different sizes that arrive at surface at different times, and the drill cuttings originate from different formation layers at different depths along the wellbore. Such techniques may include extracting samples of drill cuttings from the drilling fluid and repeating this step as necessary to provide samples of drill cuttings that arrive at surface at different recorded times; characterizing one or more formation attributes associated with the drill cuttings; and for each formation attribute, estimating a distribution of formation attribute characterization versus depth of provenance.

摘要： A system for drilling a wellbore is disclosed. The injection pump releases the taggant into the mud stream traveling downhole. The taggant attaches to the rock cuttings and it is detected on the surface by the taggant detector. The taggant detector provides the data relating to the taggants detected in the drilling fluid. The data is analyzed by taggant analysis and control engine, which produces an injection profile. Based on the injection profile, the IoT Controller adapts the parameters of the taggant injection pump to achieve a real-time optimization of the taggant injection.
