Patent number: 11015445Abstract: A property of a downhole fluid, for example, a chemical species or ion concentration, may be accurately determined and logged based on measurements received from an optical detector where the optical detector is fed information or signals from an optical system coupled to one or more electrochemical probes calibrated for one or more properties of a fluid. The one or more electrochemical probes provide a potential to the optical system based, at least in part, on exposure to the downhole fluid. The optical system receives an optical signal from a light source that is transmitted via a transmission line, such as a fiber optic cable. Downhole information from the optical system is transmitted to the surface via the same or another transmission line. Thus, the signals are in the optical domain rather than the electrical domain. Multiple properties may be measured simultaneously using the same transmission line.Type: GrantFiled: October 3, 2016Date of Patent: May 25, 2021Assignee: Halliburton Energy Services, Inc.Inventors: Xinwei Lan, Yenny Natali Martinez, Michel Joseph LeBlanc, Neal Gregory Skinner, John L.
