Once a fluid sample is collected or the back pressure fluid is no longer necessary, the second needle 126 is removed. When collection of the sample is completed, the first needle 116 is removed. Because the septa 112, 114 are rubber and the holes created by the needles 116, 126 are small, the holes pierced by the needles 116, 126 seal back together after the needles 116, 126 are removed and do not allow any collected fluid to escape the reservoir 136.

  • the body may include ends that are spaced apart at an angle of less than 180°. For example, an axis extending through one end may be spaced apart from an axis extending through the other end by 90°.
  • the ends 104, 106 define necked portions 122, 124, but in other implementations, the ends may not include necked portions.
  • glass is used for the body material in the implementation shown in FIG. 1, other suitable materials that are rigid, transparent, and gas impermeable may be used instead.
  • rubber is used for the septa material in FIG. 1, other suitable materials may be used that allow the septa to seal the openings and self- seal around the needles and against itself when the needles are removed.
  • the body 102 described above in relation to FIG. 1 is cylindrical, but other shaped bodies may be used in other implementations.
  • the device 100 may need to be purged several times (e.g., 2, 3, 4, 5, or more times) before the sample is sealed within the reservoir
  • the second needle 126 allows continuous flow through the reservoir for the purging process until the sample is ready to be taken, which makes the process easier and more efficient for the collector.
  • the glass body of the collection device 100 shown in FIG. 1 is easy to clean, which allows the body to be reused for subsequent samples.
  • the glass body is also transparent, which allows the collector to see if bubbles are developing in the collected fluid and vent the gas or adjust the collection process if necessary.
  • the glass body prevents gases from diffusing through it over time, preserving the sample until it can be tested.
  • the collection device 100 allows for the collection of fluids at their source (e.g., collection of groundwater at the well, surface waters, ocean water, lake water), which increases the likelihood that the gases dissolved within the fluid are maintained in the sample. Furthermore, the device 100 is useful for shallow collection (e.g., wells that are less than or equal to 100 feet deep) as well as deep collection that may be necessary with oil and gas operations (e.g., wells that are over 2000 feet deep). In addition, the device 100 is useful for a variety of fluids having dissolved gases. And, the flow through design of the device 100 allows for the elimination of air bubbles during collection while still allowing for the collecting of supersaturated dissolved gases within the collected fluid. The device 100 is easy to use in the field and requires less steps for set up than known collection devices, which reduces the opportunity for collector errors and increases the likelihood of obtaining good samples.

Abstract

Divers modes de réalisation comprennent des dispositifs et des procédés de collecte d'un fluide (par exemple, de l'eau souterraine), et de conservation de l'échantillon collecté à l'intérieur du dispositif de collecte pendant le transport du champ au laboratoire. Le dispositif de collecte comprend un corps creux ayant une première et une seconde extrémité, et chaque extrémité définit une ouverture. Le dispositif de collecte comprend également une cloison à l'intérieur de chaque ouverture et une aiguille amovible à l'intérieur de chaque cloison. Chaque aiguille a une première extrémité dans un réservoir défini par le corps et à l'extérieur des cloisons, et une seconde extrémité à l'extérieur du réservoir et à l'extérieur de la cloison. Une aiguille est utilisée pour collecter le fluide, et l'autre aiguille est utilisée pour évacuer le gaz et/ou le fluide du dispositif, ou appliquer une contre-pression au fluide pendant la collecte. Le corps du dispositif de collecte est rigide, transparent et imperméable aux gaz (par exemple, en verre).
