Abstract:
1. A method of automating control, remotely monitoring, and controlling, a gas extraction assembly coupled to gas pipeline section, said method comprising the steps of: coupling said gas extraction assembly to either a gas wellhead or a first pipeline section to receive gas from said gas wellhead or said first gas pipeline section; coupling said gas extraction assembly to either the outlet of a gas wellhead or a second pipeline section and providing gas to either the said outlet of a gas wellhead or the said second gas pipeline section; coupling a control panel to a variable frequency drive of said gas extraction assembly and to a plurality of sensors configured to measure a plurality of operating parameters and to a sensor configured to measure an output parameter of said variable frequency drive; measuring an output parameter of said variable frequency drive and said plurality of operating parameters at selected intervals and supplying signals reflective thereof to said control panel; determining the diurnal condition at the location of said gas extraction assembly; adjusting said output parameter of said variable frequency drive in response to said determined diurnal condition and said measured plurality of operating parameters; repeating adjusting and measuring to maintain said output parameter of said variable frequency drive and said plurality of operating parameters at optimum values.
