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 tubular defines a central flow passage. A camera has an aperture and attached to an outer surface of the tubular with the aperture oriented away from the outer surface of the tubular. A lost circulation media reservoir is circumferentially surrounding at least a portion of the outer surface of the tubular. The lost circulation media reservoir is adjacent to the camera. The lost circulation media reservoir includes actuable gates along a periphery of the lost circulation media reservoir. A trigger is communicably coupled with the actuable gates and configured to actuate the actuable gates.

摘要： Quality factors associated with formation pressure measurements at various depths in the geologic formation are determined based on one or more well logs of formation properties in a geologic formation. A formation testing tool with two or more probes is positioned in a borehole of the geologic formation based on the quality factors. The two or more probes in the borehole perform respective formation pressure measurements, where each formation pressure measurement is performed at a different depth. The formation pressure measurements and the given distance between the two or more probes indicate a formation pressure gradient.

摘要： A method comprises receiving a measurement of a pressure in a subsurface formation at a number of depths in a wellbore formed in the subsurface formation across a sampling depth range of the subsurface formation to generate a number of pressure-depth measurement pairs and partitioning the sampling depth range into a number of fluid depth ranges. The method comprises performing a fitting operation over each of the number of fluid depth ranges to determine a fluid gradient for the type of the reservoir fluid for each of the number of fluid depth ranges. The method comprises generating a solution set of one or more solutions based on the fluid gradient of the reservoir fluid for each of the number of fluid depth ranges determined from performing the fitting operation, wherein each solution defines a partitioning of the sampling depth range and the fluid gradient of each fluid depth range.

摘要： The invention is a method of determining an electrofacies interpretation of measurements relative to at least a portion of at least one well drilled through an underground formation. The method comprises applying supervised or unsupervised classification methods to measurements in order to determine learning information. Supervised classification methods are subsequently applied to the measurements, the classification methods being trained by learning information. An ensemble classification method is then applied to the results of the supervised classification methods to determine the electrofacies interpretation of the measurements.

摘要： A method for determining a hydrocarbon concentration from drilling fluid includes pumping the drilling fluid into a wellbore and circulating a sample of the drilling fluid uphole from the wellbore so that δ13C isotopic signatures can be determined for one or more hydrocarbon components and for methane in the sample where the methane includes natural methane originating from the earth formation and artificially-produced methane caused by drill bit metamorphism (DBM). A processor is adapted to determine the concentration of the natural methane in the sample based in part on the δ13C isotopic signatures which may be performed during the drilling of the wellbore.

摘要： A device and method for collecting sample fluids from an underground source which includes sample wells terminating in a corrugated conduit and sieve. The sampling regions for each sample well is separated by a grout or expanding seal barrier. Negative pressure is optionally applied to extract fluids from the underground matrix for sampling. The device can also be used for remediating an environmental contaminant from soil or aquifers. Upon identification of at least one environmental contaminant, a remediation composition is injected into the soil or aquifer using the sampling wells of the device. The remediation fluids can be directed to specific locations by selectively utilizing one or more sampling wells to inject the remediation fluid.

摘要： The disclosed embodiments include methods to perform an in-situ determination of a formation property of a downhole formation, methods to operate a tool to perform an in-situ determination of formation properties of a downhole formation, and in-situ formation property measurement tools. In one embodiment, a method to perform an in-situ determination of a formation property includes deploying a tool into a borehole that is drilled through a formation. The method also includes isolating a source zone from an injection zone. While the source zone is isolated from the injection zone, the method further includes withdrawing a fluid that partially fills the source zone; flowing the fluid into the injection zone; injecting the fluid into a first portion of the formation that is along the injection zone; and determining at least one formation property of the first portion based on an injection of the fluid into the first portion.

摘要： A treatment system comprises a treatment bladder associated with a volume of a tubing-casing annulus of a wellhead system to be treated. The treatment bladder contains a treatment fluid and is at an elevated pressure. The treatment bladder is coupled to the tubing-casing annulus utilizing a fluid conduit through a lower fluid junction. The fluid conduit permits two-way fluid communication between the treatment bladder and the tubing-casing annulus. A method for treating the tubing-casing annulus includes coupling the treatment bladder containing the treatment fluid of the treatment system to the tubing-casing annulus of the wellhead system using the fluid conduit, establishing two-way fluid communication between the tubing-casing annulus and the treatment bladder though the fluid conduit, halting fluid communication though the fluid conduit, and decoupling the treatment bladder from the tubing-casing annulus.
