ABSTRACT:
A mobile system travels with a work crew to various remote well sites and monitors the presence of H2S (hydrogen sulfide gas) at those sites. If the concentration of H2S reaches a toxic level, the system notifies a distant host computer of not only the problem but also where the problem exists. Help can then be dispatched to the known area. In some embodiments, the system notifies the work crew when help is on the way.
