Abstract: A sonde adapted for determining one or more parameters related to hydrogen at a subsurface location. The sonde includes: a plurality of centralizer arms forming an interior space having a proximal portion and a distal portion; and a plurality of fiber optic Raman probes each disposed at the proximal portion or the distal portion of the interior space and proximate a respective one of the plurality of centralizer arms, the plurality of fiber optic Raman probes being adapted to measure a hydrogen concentration in a downhole measurement. The sonde also includes a plurality of optical probes each disposed at another of the distal portion or the proximal portion of the interior space and proximate a same or different one of the plurality of centralizer arms, the plurality of optical probes being adapted to measure downhole local gas holdup.
