Apparatus system and method for gas well site monitoring
First Claim
1. A method to capture and portray information respecting airborne noxious gases present in the atmosphere of or down-wind from a gas or oil production well-site not having access to the communications and power supply public infrastructure typically associated with populated areas, for the purpose of warning remote operators of said well-site of the presence of said gas, the method comprising:
- detect, and generate raw data respecting, each said gas present in said atmosphere;
sense atmospheric conditions that cause anomalous readings respecting any said gas so detected;
process said raw data to identify each said gas detected and the concentration thereof so as to generate processed data respecting each said gas present in said atmosphere;
wirelessly communicate locally from a plurality of sensors said raw data or said processed data to a central communication interface operating from an intrinsically safe housing;
create a data log respecting sensor performance or the identity and concentration of said gases;
detect the presence and relative signal strength of any suitable cellular wireless long-distance service, and, based on said signal strength, automatically select between said cellular wireless long-distance means and any suitable satellite transponder long-distance service;
wirelessly transmit long-distance over the Internet said raw data or said processed data, using either said cellular or satellite wireless long-distance service, to a location off-site;
receive said raw data and said processed data at a specified IP address and securely portray through an Internet serving call centre at least a portion of said processed data respecting each said gas identified.

Abstract
A System and a Method of initializing and using that system are described in various embodiments all suitable for use remotely monitoring gas escapes on oil or gas well-sites, particularly as early warning technologies for use in preventing injury to workers or populations adjacent those well-sites. The system efficiently uses the Internet to securely transmit pre-processed data off-site for a range of different uses either directly to well-site operators or via a server for value-added handling of and convenient access by operators and others to information based on the data. The system conserves both IP addresses and communications bandwidth without compromising access to detailed data respecting well-site status. The novel system includes means for using multiple modes of long-distance communications technology that can be configured manually or that conveniently auto-senses and auto-selects the appropriate communications mode to use for transmitting data off-site via the Internet according to the location of installation of the system and whether or not it has entered an alarm condition.

4. A stand-alone electronic warning system to detect airborne noxious gases present in the atmosphere of or down-wind from a gas or oil production well-site not having access to the communications and power supply public infrastructure typically associated with populated areas, for the purpose of warning remote operators of said well-site of the presence of said gas, the system comprising:
-
at least two sensor means to detect, and generate raw data respecting, each said gas present in said atmosphere; condition sensing means for sensing atmospheric conditions that cause anomalous output from said sensor means; processor means, communicably coupled to said sensor means and said condition sensing means, to process said raw data and identify each said gas detected; a central communication interface, having an intrinsically safe housing, for electronically receiving raw data respecting each said gas from each said sensor, and for electronically receiving processed data from said processor means;
wireless local means to communicate said raw data and said processed data to said central communication interface;a cellular wireless long-distance means, communicably coupled to said central communication interface, for transmitting over the Internet to a location off-site said raw data respecting each said gas detected or said processed data respecting each said gas identified; a satellite transponder long-distance means, communicably coupled to said central communication interface, and having voice-communication means integrated therein, for transmitting over the Internet to a location off-site said raw data respecting each said gas detected or said processed data respecting each said gas identified; switching means for selecting either said cellular wireless long-distance means or said satellite transponder long-distance means; and at least one portable source of power for supplying electrical power to each element of said electronic warning system. - View Dependent Claims (5, 6, 7, 8, 9, 10)
