Abstract
A method allows an H2S alarm system installed at a remote wellsite to be monitored and configured from a distant location. Alert-signals from the alarm system to the distant location and configuration settings from the distant location to the alarm system can be transmitted using the text-messaging feature of a conventional cell phone. The cell phone, for example, can send the H2S alarm system a text message that sets the H2S concentration threshold at which the alarm system triggers an alert. When the H2S concentration reaches the threshold or a fault occurs with the alarm system, the system can send the cell phone a text message that describes the problem, identifies the location of the wellsite, and lists the names and telephone numbers of those that should be notified.
