A fugitive gas remediation (FGR) system for eliminating fugitive gas, such as surface casing vent gas produced from the casing head of an oil well, or so-called casinghead or Bradenhead gas, and other fugitive gas sources. An enclosure is positioned at a site with a fugitive gas source, such as a wellhead. A separator is located in the enclosure to remove liquid from the fugitive gas. A catalytic heater is located in the enclosure and coupled to the separator to react with the fugitive gas and produce heat in the enclosure. A pilot gas source can provide pilot gas to the catalytic heater.
