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.

Apparatus and methods for improved fluid sampling are disclosed. A sampling bottle for collection of a fluid sample comprises concentrically arranged first, second and third sampling containers (304A, 304B, 304C). First, second and third check valves (311, 312, 314) regulate flow of the sampling fluid from outside the sampling bottle into the first sampling container, and into the second and third sampling container.

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 a hub. 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. The hub can form a lapped joint. 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.

The invention discloses a spatial and temporal feature-based method for measuring domestic wastewater effluent loadings, comprising the following steps: establish a model for measuring regional domestic wastewater effluent loadings; calculate regional population distribution raster data; obtain per capita effluent loading coefficients with spatial and temporal differences; calculate regional domestic wastewater effluent loadings; and compare and analyze the temporal fluctuation features and spatial variation features of regional domestic wastewater effluent loadings and identify hotspot periods and areas of effluent loadings. Compared with the prior art, the method for measuring domestic wastewater effluent loadings provided by the present invention is flexible, convenient and highly universal, which can significantly raise the temporal-spatial resolution of the pattern of regional domestic wastewater effluent loadings. The data needed are also publicly available. This invention can help identify key pollution areas and periods and lay a methodological foundation for precision pollution control.

A flow through fluid sampling system includes a sample tube and a cap. The sample tube is configured to collect a sample of a fluid and has an open top. The cap is configured to be secured to the sample tube to close the open top. The cap includes an inflow port configured to allow fluid to enter the fluid sample tube, an outflow port configured to allow fluid to leave the sample tube.

A sampling device (1) for filling a sample vessel (4) with sample material from a material container, wherein the sampling device (1) comprises a first locking unit (2), a sterilization unit and a sampling chamber (3), wherein the sampling chamber (3) has an internal chamber space (5), a manipulation unit (6), an opening unit (7) arranged within the internal chamber space (5) as well as a coupling unit (8) arranged within the internal chamber space (5), the first locking unit (2) is arranged between the material container and the coupling unit (8), and the sterilization unit is connected to the internal chamber space (5) and configured to sterilize the internal chamber space (5), wherein the manipulation unit (6) is configured to accommodate the sample vessel (4) at least in part within the internal chamber space (5), movable between the opening unit (7) and the coupling unit (8), the opening unit (7) is configured to open and close the sample vessel (4), and the coupling unit (8) is configured to be coupleable to the sample vessel (4).

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.

A low-pressure cryogenic fluid sampling system includes a cryogenic sample handle assembly; a transfer and vaporization tubular loop; and a sample vessel. The sample handle assembly connects to a cryogenic storage vessel containing a cryogenic fluid. The tubular loop connects to the cryogenic sample handle assembly. The sample vessel removably connects to the transfer and vaporization tubular loop and accommodates a gaseous sample having a pressure lower than about 200 kPa. A method of collecting a gaseous sample with the sampling system includes purging the sample vessel; actuating the handle to purge and refrigerate the tubular loop; extracting a volume of a cryogenic fluid from the storage vessel into the loop to vaporize the cryogenic fluid and produce a gaseous sample; and transferring the sample from the tubular loop into the sample vessel. The sampling system is safer, maintains stoichiometric quantities in the cryogenic liquid, and reduces cross contamination.

A water sampling device for obtaining a water sample within an environment isolated from adverse weather conditions, such as rain or a debris filled atmosphere. The water sampling device includes a chamber having a base, one or more sidewalls, and an upper end. The interior of the chamber includes a faucet disposed on a sidewall and connected to a hose that extends through the sidewall to the exterior of the chamber, wherein the hose can collect water from a water source. A valve is disposed within the faucet in order to control the flow of water therethrough. The water sampling device further includes a pair of gloves disposed on opposing sidewalls, wherein the gloves extend into the chamber so as to allow a user to manipulate the water sample therein. A stand is secured to the exterior of the chamber in order to support the chamber in an upright position.
