The present disclosure is directed to systems, methods and tools that measure ionic concentrations and downhole enthalpy of a flowing geothermal fluid in real-time at high-temperature and pressure. The systems, methods and tools include measuring the concentration of selected naturally occurring ions found in the liquid phase of the geothermal fluid throughout the wellbore using novel electrochemical sensor technologies. The change in liquid-phase ion concentration will be used to calculate the proportion of liquid to steam and allow for accurate enthalpy measurements. The techniques and technologies described here can be applied to any application of electrochemical sensing in extreme environments.

A suppression module, a suppression assembly, and a drilling tool are disclosed. The suppression module includes a spindle having a first end and a second end, an ear plate slideably disposed between the first end and the second end, a spring positioned between the ear plate and the first end, and an activation mechanism coaxially disposed around the second end of the spindle. The activation mechanism engages the ear plate, activating the spring, or disengages the ear plate, deactivating the spring. The suppression assembly includes at least two suppression modules in series coupled to a processor. The suppression modules are activated or deactivated by the processor, each of the suppression modules being activated or deactivated independent of the other suppression modules. The drilling tool includes a drill pipe, a drill bit, a vibration sensor, and a suppression assembly between the drill pipe and the drill bit.
