Publication number: 20240018868Abstract: A well testing system and method is disclosed that reduces the surface equipment needed for well testing by providing a closed loop fluid flow path where the fluids produced during the well test are not brought to the surface for storage or flaring but instead are disposed in a downhole zone. The system and method are implemented using a simplified acoustic communications network where a hub device generates and transmits a single multiple hop query that includes multiple commands or queries directed to targeted downhole tools.Type: ApplicationFiled: November 30, 2021Publication date: January 18, 2024Inventors: Elias Temer, Carlos Merino

Patent number: 10551183Abstract: A system disclosed herein is for determining position of a distal end of a tubular string in a wellbore formed in a subsurface formation. The system includes casing lining the wellbore, with the casing carrying a plurality of radioactive sources. A tubular string is disposed in the wellbore and carries a radiation sensor along a length thereof. A processor is associated with the radiation sensor, and is configured to measure intensity of radiation received from the plurality of radioactive sources, and determine the position of the distal end of the tubular string by correlating a formation or wellbore fluid property that varies as a function of position within the wellbore and the measured intensity of the radiation received from the plurality of radioactive sources.Type: GrantFiled: December 6, 2016Date of Patent: February 4, 2020Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Carlos Merino, Clement Probel
