Patent number: 11931822Abstract: A technique facilitates a welding operation in a variety of difficult environments, including downhole environments, to enable formation of a dependable connection between components. A tool may be constructed to contain a material mixture used in the welding operation. The tool is conveyed to a position adjacent a weld region of components to be welded together. The material mixture is of a type which may be ignited to initiate a reaction which forms a molten metal from at least one constituent in the material mixture. Additionally, the tool comprises a nozzle oriented to direct the molten metal to the weld region so as to form a secure, welded connection between the components.Type: GrantFiled: October 19, 2020Date of Patent: March 19, 2024Assignee: Schlumberger Technology CorporationInventor: Hongfa Huang

Publication number: 20240080294Abstract: A first device is logged in with a first user account. The first device displays an avatar of a second user account in a first user interface of the first device. In response to an interaction instruction triggered on the avatar of the second user account, the first device generates an interaction message according to a first field corresponding to the first user account, an action description field corresponding to the interaction instruction, and a second field corresponding to the second user account. The first device transmits the interaction message to a second device that is logged in with the second user account.Type: ApplicationFiled: November 10, 2023Publication date: March 7, 2024Inventors: Xi YAN, Wancheng ZHOU, Qing HUANG, Junjie LIANG, Hongfa QIU, Yanlan LIU, Runjia HUANG, Qiuchen JIN, Zhihao CHEN, Xucheng TANG, Bohan CAI, Jingqiong FENG

Publication number: 20140209381Abstract: A charge assembly for incorporation into a downhole tool to induce pressure at an interior of the tool during a downhole application. The assembly includes a reactive powder metals that is particularly configured of a reaction rate slower than that of a high energy explosive directed at the application. Thus, upon triggering of the explosive and downhole application in a high pressure well environment, reaction of the powder metals may serve to substantially reduce any pressure differential at the tool. As such, shock related damage due to sudden introduction of pressure differential wave to the tool may be minimized.Type: ApplicationFiled: January 28, 2013Publication date: July 31, 2014Applicant: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Hongfa Huang, Brenden M.
