A method for analyzing a drilling fluid receiving a drilling fluid sample from a flow of the drilling fluid at a surface of a borehole being drilled in a subterranean formation and extracting, using a gas extraction and sampling system, a dissolved gas from the drilling fluid sample. The method includes determining, using a gas chromatograph, a concentration over time of at least one chemical species of a dissolved gas from the drilling fluid sample and generating an area per concentration curve based on the concentration over time. The method includes determining, using a gas extraction and sampling system, at least one concentration value of the at least one chemical species of the dissolved gas from the drilling fluid sample and correcting bias caused by the gas extraction and sampling system, wherein correcting the bias comprises modifying the at least one concentration value based on the area per concentration curve.

An insertion-type probe main body for insertion into a pipe transporting gas and a method for making such an insertion-type probe main body are provided. The probe main body includes: an elongate upper tubular portion; an elongate lower tubular portion which is integral with and having a diameter smaller than the upper tubular portion; a bore which extends between the upper and lower tubular portions; and helical fins integrally formed on the lower tubular portion and which wind along and around an outer surface of the lower tubular portion and which overlap each other. A radial extension of the lower tubular portion plus helical fins corresponds to an external radius of the upper tubular portion, so that the helical fins extend in a streamline fashion from the upper tubular portion. Numerous other aspects are provided.

A system according to an exemplary aspect of the present disclosure includes a probe configured to collect a sample gas stream, a pressure reduction section, a heated sorbent trap section, and a control loop. The pressure reduction section has a critical orifice and a heater configured to heat the critical orifice. The heated sorbent trap section is configured to receive a first portion of the sample gas stream, and the control loop is configured to receive a second portion of the sample gas stream.

A Sampler and process for collecting, growing, inoculating and evaluating microbes in-situ. The Sampler may be loaded with an active or inert media to assist with the collection of microbes. It is closed and lowered to a desired depth. Sampler is opened to initiate sampling. Materials are added to the sampler to stimulate growth or change the environment. To collect and grow in situ microbes, the sampler is left open for a period of time, a trigger closes and seals the sampler capturing contents specific to that location. The sampler is lifted preserving the in-situ conditions from the collection location. The contents of the sampler can be interrogated through sealed ports at the field site or at a remote location. The sampler can also be utilized as a biologic reactor allowing researchers to connect laboratory equipment to analyze, modify, or cultivate the collected sample.

An apparatus for sampling landfill gas from a landfill flowing through a pipe. The apparatus may comprise: an enclosure configured to receive a section of the pipe; a gas sampling port in the section of the pipe; at least one sensor device disposed in a region of the enclosure, the at least one sensor being coupled to the section of the pipe through the gas sampling port; and thermal insulation positioned to retain heat from the section of the pipe in the region of the enclosure. A method of operating a landfill gas recovery system. The method may comprise: flowing gas from a well riser pipe through a sampling subsystem to a collection system; and heating a portion of the sampling subsystem with the gas flowing from the well riser pipe to the collection system.

The present application discloses a gas sampling device, in particular, a fractionation gas sampling device comprising a heat exchanger, and the heat exchanger comprises one or more groups of tubes, wherein, a guide plate is disposed in the tubes. The fractionation gas sampling device further comprises a coke cleaning mechanism having a decoking head, and the decoking head has a circular arc guide. The fractionation gas sampling device has a large heat exchange area, a high heat exchange efficiency, and overcomes the surface tension between liquids so as to avoid generating liquid columns; moreover, by combining with the coke cleaning mechanism, the fractionation gas sampling device not only achieves excellent technical effects relevant to decoking, but also effectively prevents from a blocking phenomenon of the decoking head, thereby realizing an automatic cleaning.

Embodiments of the invention include systems and methods for capturing crowd wisdom to be tested for individualized treatment plans. These systems and methods include data mining crowd sourced health related information and unstructured medical narratives and storytelling to identify treatment plans and general techniques that individuals with chronic diseases/symptoms, including but not limited to IBD and other immune invisible neglected and stigmatized diseases, use to improve their general health and wellbeing. A system for testing the treatments effectiveness in a population and then in an individual is also disclosed.

A control system for controlling extraction of landfill gas from a landfill via a gas extraction system comprising well piping, the landfill gas having a first temperature when extracted, the control system comprising: a gas composition chamber coupled to the well piping and comprising at least one sensor configured to measure one or more characteristics of a landfill gas sample in the gas composition chamber; a temperature control mechanism configured to heat the landfill gas sample in the gas composition chamber to a second temperature at least a threshold amount greater than the first temperature; and a controller configured to control the at least one sensor to measure the one or more characteristics of the landfill gas sample in the gas composition chamber when a temperature of the landfill gas sample in the gas composition chamber is at least the threshold amount greater than the first temperature.

A gas monitoring and control system including a gas sampling chamber, sampling inlet and outlet valves, a pump and a controller. Sensors are disposed within the interior chamber that sense characteristics of a gas from a gas source and generate representative signals. The sampling inlet and outlet valves i) allow the gas into the gas sampling chamber while operating in a gas sampling state, and ii) allow ambient air into the gas sampling chamber while operating in a purge state. The pump i) causes the gas to flow through the gas sampling chamber while operating in the gas sampling state or ii) causes ambient air to flow through the gas sampling chamber while operating in the purge state. The controller causes the sampling inlet and outlet valves, and the pump to alternate operating in the gas sampling or purge state to selectively expose the sensors to the gas.
