  • Potentiometric sensor for wellbore applications
    Patent number: 6740216
    Abstract: A potentiometric sensor for wellbore applications having a permanent aqueous contact between measuring and reference electrode, whereby contact is ensured by discharging the internal solution from the reference electrode directly onto a measuring (ion-sensitive) membrane and protecting the reference junction of the reference electrode with water wet porous material, such as sintered glass. It is advantageously applied to oil-water mixtures under high pressure and/or temperature.
    Type: Grant
    Filed: May 4, 2001
    Date of Patent: May 25, 2004
    Assignee: Schlumberger Technology Corporation
    Inventors: Igor Igorevitch Diakonov, Alexander Vladimirovitch Zotov, Igor Nikolaevitch Solodov, Evgenii Grigorevitch Osadchii, Alexander D. Khoteev
