Landfill gas, in addition to being flammable and odorous, contains a significant amount of greenhouse gases. It is an integral part of an environmental permit that landfill gas is controlled and, on many sites, it is utilised for power generation.
Using our extensive expertise and high performance equipment, we are able to drill to depths in excess of 85m. Wells are typically drilled to a diameter of 450mm and casing sizes are installed as specified by the client. Field engineers are available for butt fusing casing and pipework.
Dragon Drilling is committed to identifying and improving drilling techniques to ensure the inherent complex challenges typically associated with landfill gas extraction can be efficiently overcome. All our rigs are equipped with our remote winch-operated incline control system for the safe drilling on inclines of 1:3, which was designed and manufactured in-house.
Gas extraction boreholes have an upper seal of fully hydrated bentonite, which is installed using our bentonite mixing machine. This equipment attaches to a mini excavator and was granted Patent GB 2433215 in 2007.
