  • Apparatus and methods to analyze downhole fluids using ionized fluid samples
    Patent number: 8230916
    Abstract: Apparatus and methods to analyze downhole fluids are described herein. A disclosed example method involves obtaining a sample of a downhole fluid. Additionally the example method involves ionizing at least a portion of the sample to decompose molecules having a relatively high molar mass into molecules having a relatively lower molar mass. Further, the example method involves analyzing the ionized portion of the sample to determine a parameter of the downhole fluid sample.
    Type: Grant
    Filed: October 6, 2008
    Date of Patent: July 31, 2012
    Assignee: Schlumberger Technology Corporation
    Inventors: Ernest N. Sumrall, Anthony Goodwin, Erik Quam, Chengli Dong, Oliver C. Mullins
