Description
The site of Canadian Pacific Langevin Number 1 and 2 Gas Wells is a railway siding north of the former town of Alderson, part of a legal subdivision on the Canadian Pacific Railway (C.P.R.) line approximately 58 kilometres west of Medicine Hat.
Heritage value
The Canadian Pacific Langevin Number 1 and 2 Gas Wells are significant as the site of the discovery of natural gas in Alberta (and possibly Canada).
In December 1883, natural gas was discovered accidentally at Langevin when a C.P.R. drilling crew in search of water drilled Well No. 1. Water supplies were scarce on the prairies but essential to the completion of the rail line: for work crews, new townsites along the line, and most importantly, the steam engines. Drilling wells also provided the Geological Survey of Canada with data on the shallow geomorphology of the area. In 1884, No. 2 was the first well drilled in Alberta for the express purpose of using natural gas as a fuel.
After 1900 settlers disregarded the C.P.R.'s planned townsite north of the main rail line, where the wells were located, in favour of land south of the rail line which was closer to a water supply; water was more pressing a need for farmers than an unproven kind of energy. Later, however, natural gas proved to be a cheap, efficient, reliable source of energy, and was integral to the development of industry and manufacturing (notably of ceramics, i.e. brick and tile) in southern Alberta.
Well No. 2 demonstrated amazing longevity for such an early discovery. Continued leakage prompted concerns about possible explosions until both wells were permanently capped in 1954, although natural gas is still produced from the same Milk River formation.
