  • Systems and methods for determining the presence of cement behind at least one casing using spectroscopy measurement
    Patent number: 11774629
    Abstract: A presence of cement may be identified based on a downhole tool that may emit neutrons into a wellbore having at least one cement casing. The neutrons may interact with the particular material via inelastic scattering, inelastic neutron reactions, capture of neutrons and/or neutron activation through one of these reactions and cause a material to emit an energy spectrum of gamma rays, and wherein the downhole tool is configured to detect an energy spectrum of the gamma rays that is specific to at least one of a plurality of elements and associated a region within the wellbore. An amount of elements, such as calcium and silicon, may be determined from the gamma ray spectra that may indicate a present of cement within the wellbore.
    Type: Grant

    Date of Patent: October 3, 2023
    Assignee: SCHLUMBERGER TECHNOLOGY CORPORATION
    Inventors: Pascal Millot, Adil Busaidy, Jeffrey Miles, Tong Zhou, Christian Stoller, David Rose, Richard Radtke
