Systems and techniques are described for a fluid diode. In some examples, a fluid diode can include a first fluid path for a first flow of fluid to traverse the fluid diode via a first flow direction and a second fluid path for a second flow of fluid to traverse the fluid diode via a second flow direction. The first flow direction can be associated with a first pressure drop and the second flow direction can be associated with a second pressure drop that is different than the first pressure drop. Moreover, the first fluid path and the second fluid path can be configured to remain open to the first flow and the second flow in the first flow direction and the second flow direction.

Fluid diode

A device for coating an interior surface of a housing defining a volume comprising a plurality of reactant gas sources including reactant gases for one or more surface coating processes; first and second closures to sealingly engage with an inlet and outlet of the volume of the housing to provide an enclosed volume; a delivery line fluidically coupled to the first closure and the plurality of reactant gas sources to deliver the reactant gases to the enclosed volume; and an output line fluidically coupled to the second closure to remove one or more reactant gases, byproduct gases, or both from the enclosed volume. A method for coating an interior surface of a housing is also provided.

Depositing coatings on and within housings, apparatus, or tools

A downhole sample extractor includes a sample container chamber that holds a sample container containing a downhole sample. The downhole sample extractor also includes a sample extraction chamber having an internal chamber that is partially filled with a carrier solution, wherein the downhole sample is mixed with the carrier solution in the internal chamber of the extraction container. The downhole sample extractor further includes a first piston that, when actuated, inserts the sample container into the internal chamber of the sample extraction chamber.

Downhole sample extractors and downhole sample extraction systems

Downhole tool is provided that includes a body, an intake port for receiving fluid from external the body, a pump, a filtration device, and an exit port. The pump is in fluid communication with the intake port for withdrawing fluid through the intake port. The filtration device has a particulate removing filter, and a flow line extending from the intake port to the filtration device. The filtration device is contained within the body and is in fluid communication with the intake port. The exit port is in fluid communication with the filtration device for ejecting the fluid to external the body.

Downhole tool with filtration device

The present application relates sensing reactive components in fluids by monitoring band gap changes to a material having interacted with the reactive components via physisorption and/or chemisorption. In some embodiments, the sensors of the present disclosure include the material as a reactive surface on a substrate. The band gap changes may be detected by measuring conductance changes and/or spectroscopic changes. In some instances, the sensing may occur downhole during one or more wellbore operations like drilling, hydraulic fracturing, and producing hydrocarbons.

Bandgap detection of reactive components in fluids

A formation tester comprises a body having an outlet; a probe extendable from the body and having a sealing pad; and a flow line within the body, wherein the flow line has an entry end connectable to the probe and has an exit end connectable to the outlet in the body; and a reactive filter material in the flow line downstream of the entry end of the flow line, wherein the reactive filter material sorbs and entraps an analyte in a wellbore fluid.

Gas bubble migration can be managed in liquids. In one example, a system can execute wellbore-simulation software to simulate changes in gas dissolution in a liquid over time. This may involve dividing the wellbore into segments spanning from the well surface to the downhole location, each segment spanning a respective depth increment between the well surface and the downhole location. Next, for each time, the system can determine a respective multiphase-flow regime associated with each segment of the plurality of segments based on a simulated pressure level, a simulated temperature, a simulated pipe eccentricity, and a simulated fluid velocity at the segment. The system can also determine how much of the gas is dissolved in the liquid at each segment based on the respective multiphase-flow regime at the segment. The system can display a graphical user interface representing the gas dissolution in the liquid over time.

A method and system for measuring drilling fluid filtrate. The method may comprise disposing a downhole fluid sampling tool into a wellbore at a first location, activating a pump to draw a solids-containing fluid disposed in the wellbore into the downhole fluid sampling tool, drawing the drilling fluid with the pump across the at least one filter to form a drilling fluid filtrate, drawing the drilling fluid filtrate with the pump through the channel to the at least one sensor section, and measuring the drilling fluid filtrate with the at least one sensor. A system may comprise a downhole fluid sampling tool. The downhole fluid sampling tool may comprise at least one multi-chamber section, at least one sensor section, at least one filter, a pump, and a channel.

A siphon pump chimney can be used in a mini-drillstem test to increase formation fluid flow rates. A formation tester can be coupled to a siphon pump chimney via a wet connect assembly to transfer formation fluid from a fluid-bearing formation. The siphon pump chimney can receive the formation fluid through the wet connect and disperse the formation fluid into a drill pipe that is flowing drilling fluid. The siphon pump chimney can include check valves to prevent the drilling fluid from entering the siphon pump chimney. The siphon pump chimney can be configured to have a variable height that can reduce pressure within the siphon pump chimney to a pressure value that can be close to or less than the formation pressure, which can allow a pump to operate at high flow rates or be bypassed in a free flow configuration.

A formation test probe and a formation test system and method for implementing a self-drilling probe are disclosed. In some embodiments, a test probe includes a body having a channel therethrough to a frontside port, and further includes drill-in tubing disposed within the channel and having a front tip that is extensible from the frontside port. An exciter is disposed within the body in contact with the drill-in tubing and operably configured to induce resonant vibration in the drill-in tubing during a drill-in phase of a formation test cycle.
