A multi-phase sampling collection system includes a three-way four-port valve unit that includes a valve housing having a first port, a second port opposite the first port, and a third port. The valve unit includes an inner valve member that is movably disposed within the valve housing between a plurality of positions. The inner valve member has a main valve body that has a first valve opening, a second valve opening opposite the first valve opening, a third valve opening and a fourth valve opening opposite the third valve opening. The third valve opening is defined by a plurality of orifices for mixing incoming non-homogenous fluid to generate a mixed homogenous fluid and the fourth valve opening has a lesser diameter that the third valve opening for increasing fluid pressure drop, fluid velocity, and fluid turbulence resulting in improved mixing of the non-homogenous fluid that exits through the fourth valve opening.

Interaction of adsorbing chemicals with a downhole tool presents inaccuracies in the adsorbing chemical measurement and analysis. The principles of the present disclosure provide a method and system of sampling fluids including an adsorbing chemical in a subterranean reservoir. One method may include modeling an interaction between the adsorbing chemical and a downhole tool, applying the model to a measurement of the adsorbing chemical, and adjusting the measurement in response to applying the model.

Process inserts, assemblies, and related methods for use in monitoring high velocity fluids or supporting instruments that monitor and manage high velocity fluids are disclosed. Exemplary inserts include a head having a cavity for receiving an instrument, a shank, and an integral flange. The shank includes an elongated body having a first end disposed proximate to the head, a free end opposite the first end, and a threaded portion spaced apart from the first and free ends. Exemplary process insert assemblies include a process insert having a shank and a threaded support disposed around the shank. Methods of making and using process inserts are also disclosed. For example, a method of installing a process insert on a container includes inserting the free end of the process insert in the interior volume of a container containing a high velocity fluid.

A drainage bottle apparatus includes a cylindrical body portion with a base, a neck portion, a receptor opening located at a rim, a first and a second threaded inner perimeter surface, a removable sieve having a sieve outer perimeter rim thread, and a sieve base. The sieve outer perimeter rim thread mates with the second threaded inner perimeter surface. A method for extracting a rock plug sample includes using the drainage bottle apparatus in combination with a sample jar containing a rock plug sample and a liquid material. The sample jar includes a sample jar outer perimeter surface thread that mates with the first threaded inner perimeter surface of the neck portion and is turned over so as to drain the liquid material thereby separating the liquid material from the rock plug sample and the rock plug sample, now dried, may be extracted.

[Solving Means] A sample liquid-sending apparatus includes a placement portion, a suction mechanism, and a vibrator. A sample container is placed in the placement portion, the sample container containing a suspension of a sample. The suction mechanism includes a nozzle configured to be inserted into the sample container placed in the placement portion, and suctions the sample through the nozzle. The vibrator vibrates the nozzle.

A residue tube assembly includes a residue tube having an open upper end and a cap assembly including a cap sealingly secured with the open upper end and an adjustable member assembled with the cap and defining an outlet passage extending into the residue tube to define a fill limit of the residue tube, and an overflow passage extending radially outward and downward of the open upper end of the residue tube. The adjustable member is vertically adjustable in the cap to adjust the fill limit of the residue tube.

The system can also include at least one sample container and at least one unmanned aerial vehicle configured to transport the at least one sample container. The system can also include at least one valve that can be configured to open and discharge a sample of the lubricating fluid from the at least one fluid path into the at least one sample container. At least one unmanned aerial vehicle station can be configured to receive the at least one unmanned aerial vehicle. At least one retention and loading mechanism can be configured to move the at least one sample container.

An air sample collection apparatus and methods for operating the air sample collection apparatus are provided. The air sample apparatus comprises a plurality of air canisters comprising at least a first canister and a second canister, a multi-position valve comprising an outlet, and an inlet region, which are fluidly connected to a plurality of ports. Each respective port is fluidly connected to a canister of the plurality of air canisters, a pump operable to provide pressurized sample air to the inlet region of the multi-position valve, and a computing device operable to open and close each respective port fluidly coupled to each canister of the plurality of canisters.

A water quality management method for performing at least one of a quantitative analysis and a qualitative analysis of fine particles contained in water to be analyzed that includes connecting a filtration device provided with a fine particle capturing membrane for capturing fine particles to a flow pipe through which the water to be analyzed flows, allowing the water to be analyzed to flow from the flow pipe and through the fine particle capturing membrane attached to the filtration device for a predetermined period of time to capture fine particles contained in the water to be analyzed to form a fine particle capturing membrane sample, and performing at least one of a quantitative analysis and a qualitative analysis of the fine particle capturing membrane sample of a target water flow period at an arbitrary timing.

A device for analyzing a gaseous sample including a first housing including a detection assembly housed in the housing including a preconcentrator, a chromatography column and a detector intended to detect the presence of the separated compounds, a sampling assembly including a cartridge that is removable relative to the first housing, a control and processing unit housed in the housing and configured to execute an analysis operating mode capable of generating a first command for the detection assembly to analyze a first gaseous sample, a second command to determine the exceeding of at least one alert threshold and, if an alert threshold is exceeded, a third command for the sampling assembly to take a second gaseous sample.
