Abstract: Macroparticulates may be formed through at least partial self-assembly by reacting an epoxide-containing (meth)acrylic polymer or copolymer with a compound bearing a nitrogen nucleophile. An internal cavity may be formed when functionalizing the (meth)acrylic polymer or copolymer in the presence of a hindered amine base. When appropriately functionalized, the macroparticulates may be used to sequester a contaminant from a substance in need of contaminant remediation, such as produced water or flowback water from a wellbore job site. Reclaimed water obtained from the macroparticulates may be utilized to form a treatment fluid. The macroparticulates may be located within a continuous flow line, particularly within a removable cartridge, to promote removal of at least one contaminant from a substance in need of contaminant remediation.

Abstract: A wellbore gun assembly includes a chuck assembly for assembling a wellbore gun. The chuck assembly includes a chuck housing, a rotating gun chuck, and an axial gun chuck. The gun chucks have chuck jaws radially movable about a hole in the gun chucks to selectively grip a portion of the wellbore gun. The holes of the gun chucks are aligned to define a passage for receiving the wellbore gun therethrough. The rotating gun chuck is rotationally positioned about the axial gun chuck to selectively rotate the portion of the wellbore gun as the axial gun chuck moves axially about the axial gun chuck whereby the portions of the wellbore gun are threadedly connected together. The chuck assembly also includes a gantry loader loads gun components onto a feed assembly, and the feed assembly feeds gun components into the chuck assembly.

Abstract: An integrated tool processing system and a wellsite monitoring system for a wellsite. The integrated tool processing system includes a tool assembler, a tool lift, and a tool transporter. The tool assembler includes a tool conveyor and a gun builder. The tool lift is connected by a tool stager to the tool assembler. The tool lift includes a lift base to receive the downhole tool and a lift arm to lift the downhole tool. The tool transporter includes a vehicle and a boom for connection to the downhole tool. The vehicle and the boom carry the downhole tool into position for delivery at the wellsite. The wellsite monitoring system includes wellsite sensors to collect wellsite data, wellsite monitors to receive and analyze the wellsite data, and a central station to collect and further analyze the wellsite data and to operate the tool processing system based on the combined wellsite data.

Abstract: Phenyl rings provide a robust scaffold for molecular design, given the limited number of ring carbon atoms and the fixed geometry in between. Alternating groups in hexasubstituted benzenes may be directed toward opposite faces of the phenyl ring, such that orthogonal reactive groups are directed toward the opposite faces for promoting both surface attachment and introduction of functionalities suitable for promoting analyte detection. Hexasubstituted benzenes capable of covalent bonding to a surface and having functionalities capable of promoting detection of one or more analytes in fluids may be realized. An analytical response of the hexasubstituted benzenes or a change thereof may be correlated to an amount of at least one analyte present in a fluid, including both single- and multi-phase complex fluids.

Abstract: Macroparticulates may be formed through at least partial self-assembly by reacting an epoxide-containing (meth)acrylic polymer or copolymer with a compound bearing a nitrogen nucleophile, such as iminodiacetic acid or ethylenediamine. When the epoxide-containing (meth)acrylic polymer or copolymer is formed into a predetermined shape before reaction with the compound bearing the nitrogen nucleophile, a profile of the predetermined shape may be at least partially maintained and undergo expansion in the course of forming the reaction product, thereby producing macroparticulates having a larger volume than the predetermined shape itself. An internal cavity may be formed when generating the macroparticulates in this manner. Optionally, a hexasubstituted benzene or a supramolecular receptor may be adhered to a surface portion of the macroparticulates, either covalently or non-covalently.

Abstract: Phenyl rings provide a robust scaffold for molecular design, given the limited number of ring carbon atoms and the fixed geometry in between. However, it can be difficult to form highly substituted phenyl rings suitable for covalent attachment of multiple moieties thereto. Moreover, binding phenyl rings to a surface in a fixed geometry may be difficult. Hexasubstituted benzenes having certain structural features may alleviate the foregoing difficulties by providing versatile groups for further functionalization and surface attachment. Such hexasubstituted benzenes may have a structure of in which each X is independently Cl, Br or N3, and each Z is independently —CH(Br)CH3, —CH(N3)CH3, —CH?CH2, —CH2CH3, —CH2CH2SiR?3 (R?=hydrocarbyl), or Alternating groups in the hexasubstituted benzenes may be directed toward opposite faces of the phenyl ring, such that orthogonal reactive groups are directed toward the opposite faces. Certain groups may facilitate surface attachment of the hexasubstituted benzenes.

Abstract: An apparatus includes a tube, first and second pairs of electrodes, a reference device, and a processor. The processor determines a speed of a fluid traveling between the first and second pairs of electrodes and determines a reference conductance of the fluid using the reference device. The processor also determines a measured conductance of the fluid using at least one of the first and second pairs of electrodes and determines, based on the reference conductance and the measured conductance, a cross-sectional area of the fluid at an electrode. The processor further adds a correction factor to the determined speed to produce a bulk speed of the fluid. The processor further determines a volumetric flow rate of the fluid based on the bulk speed and the determined area and determines a volume of the fluid based on the determined volumetric flow rate.

A trace of the material is collected on a pad of the card component, collected by swiping the pad on suspected surface or exposure to the suspected air volume. A novel card component is disclosed that when inserted in a chemical detection unit (CDU), releases reaction chemicals from flexible walled capsules in desired sequence. The exposed pad containing trace material and chemicals are heated in the chemical detection unit to produce a spectral pattern that is analyzed by the optical electronics in the CDU and results are displayed, stored and/or transmitted over a communications network.
