- a mobile hydrogen sulfide monitor that is movable between the first well site and the second well site, wherein the mobile hydrogen sulfide monitor when at the first well site determines whether the hydrogen sulfide at the first well site exceeds an allowable limit, and wherein the mobile sulfide monitor when at the second well site determines whether the hydrogen sulfide at the second well site exceeds the allowable limit;
an alarm associated with the mobile hydrogen sulfide monitor, wherein the alarm is generated at the first well site in response to the mobile hydrogen sulfide monitor determining that the hydrogen sulfide at the first well site exceeds the allowable limit, and wherein the alarm is generated at the second well site in response to the mobile hydrogen sulfide monitor determining that the hydrogen sulfide at the second well site exceeds the allowable limit;
a mobile transmitter associated with the mobile hydrogen sulfide monitor and transmitting an alarm signal as a result of the mobile hydrogen sulfide monitor determining that the hydrogen sulfide exceeds the allowable limit;
a wireless communication link that conveys the alarm signal from the mobile transmitter to the designated host computer, a first location signal that identifies the location of the first well site, wherein the first location signal is communicated from first well site to the designated host computer when the mobile transmitter is at the first well site and the hydrogen sulfide exceeds the allowable limit; and
a second location signal that identifies the location of the second well site, wherein the second location signal is communicated from second well site to the designated host computer when the mobile transmitter is at the second well site, whereby the designated host computer becomes informed of where the hydrogen sulfide has exceeded the allowable limit.

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.
