Abstract
The level of hydrogen sulfide in drilling fluid within a well formed in the Earth is assessed in an ongoing and/or in situ manner. The well may be constructed for the removal of hydrocarbons from the Earth. The assessment of hydrogen sulfide level may be provided in an ongoing manner such that real time, or near real time, fluctuations in hydrogen sulfide levels in the drilling fluid within the well may be conveyed to users. This may provide various advantages over systems in which drilling fluid must be extracted and separately tested for hydrogen sulfide content, and/or in which assessments of hydrogen sulfide level require time for performance.
