  • Methods and apparatus for the downhole analysis of the composition of formation gases
    Patent number: 10927668
    Abstract: Methods and apparatus are provided for determining down-hole the composition of natural gas from a formation. Some methods include downhole measurements of the near-infrared spectra and the Joule-Thomson coefficient of the gas, and processing the results of the downhole measurements in order to obtain a determination of the amounts of a plurality of natural gas components such as CH4, C2H6, CO2, N2, and H2S.
    Type: Grant
    Filed: December 10, 2018
    Date of Patent: February 23, 2021
    Assignee: Schlumberger Technology Corporation
    Inventors: Jaisree Iyer, Terizhandur S. Ramakrishnan
