Publication number: 20240093586Abstract: A mobile transport is used for slurry at a wellsite. An enclosure on the mobile transport has a chamber configured to hold the slurry, and a weighing assembly on the mobile transport is configured to weigh solid content of the slurry discharged from the wellsite to the chamber. One or more level sensors on the mobile transport are configured to measure a level of the slurry in the chamber, and one or more gas sensors on the mobile transport are configured to measure a property (e.g., content, proportion, etc.) of gas content in the chamber. A vapor recovery assembly on the mobile transport is in communication with the chamber. The vapor recovery assembly is configured to draw the gas content of the slurry from the chamber or capture any gas out and prevent it from emitting into the atmosphere. A control system is in operational communication with the weighing assembly, the one or more level sensors, the one or more gas sensors, and the vapor recovery assembly.Type: ApplicationFiled: September 18, 2023Publication date: March 21, 2024Inventors: Suman Deb ROY, Cole STOUT

Publication number: 20220357719Abstract: An automated computer-vision system is used for timing the sand drainage in a sand management arrangement that handles flowback of sand and other solid materials in a slurry of flow from well(s) at wellsite(s). The automated system uses infrared imaging of flowback equipment to determine a level of solids (sand) in the equipment. Image processing of the temperature differences of the content in the equipment gives a demarcation of the sand and liquid separation in the equipment, which is used to determine how much sand is present. If the equipment is found to be full or above a predefined benchmark, the automated system operates a discharge skid to discharge the contents to a waste tank.Type: ApplicationFiled: May 10, 2022Publication date: November 10, 2022Inventors: Cole Stout, Suman Deb Roy

Publication number: 20220268134Abstract: A sand disposal system is used with a sand management arrangement that handles flow-back of sand and other solid materials in a slurry of flow from well(s) at wellsite(s). The sand disposal system includes a tank filling module that mounts on a disposal tank at a wellsite. The module controls and weighs the disposal of the solid material or sand into the tank by actuating a flap and sensing weight with a weight sensor. The module also monitors the level in the tank to determine when emptying of the tank is needed. A control system can control operations of the module in conjunction with the other processes of the sand management arrangement.Type: ApplicationFiled: February 22, 2022Publication date: August 25, 2022Inventors: Cole Stout, Suman Deb Roy, David Johnson, Jeff Bell

Patent number: 4575524Abstract: Cathodic electrodepositable resin compositions particularly adapted for use as film forming compositions in cathodic electrodeposition processes. The resin is the reaction product of a modified epoxy formed by reacting a polyepoxide with a water soluble or water miscible polyol, an excess of polyamine, and a fatty acid. The resin, when combined with a cross-linking agent and solubilized in an aqueous electrodeposition bath, is capable of depositing high build coatings in a short period of time with a low cross-linking temperature in a cathodic electrodeposition process. The resin compositions are salted with an acid and used as components of aqueous cathodic electrodeposition baths.Type: GrantFiled: January 29, 1985Date of Patent: March 11, 1986Assignee: Inmont CorporationInventors: Terry L.
