Copșa Mică gas field
Natural gas field in Sibiu County, Romania From Wikipedia, the free encyclopedia
The Copșa Mică gas field is a natural gas field located in Copșa Mică, Sibiu County, Romania. Discovered in 1915, it was developed by Romgaz, beginning production of natural gas and condensates in 1920. By 2010 the total proven reserves of the Copșa Mică gas field were around 2.77 trillion ft3 (80 km3), with a production rate of around 3.7 million ft3/day (0.1×105 m3).[1][2][3]

The gas deposits in Romania have a very long history of exploitation, almost unique at the level of Europe and among the few such old fields that are still in production in the world.[4] A quarter of Romania's natural gas reserves (100 billion m3 (3.5 trillion cu ft)) are located in Western Moldavia, Muntenia, and the Black Sea, with the remaining 75% located near methane gas reserve sites in Transylvania.[5] A fifth of these sites are located in the Giurgeu-Brașov Depression and Sibiu County, with the remainder located in Mureș County at sites such as Luduș, Șincai, Bazna, and Nadeș.[6]: 76 [7]: 102
In the interwar period, Romania's program of geological works and drilling was amplified, highlighting the gas deposits from Copșa Mică, Bazna, Șaroș, and Șincai.[8][9]
On July 13, 1933, the biggest fire in the history of Romania occurred at gas well number 5 in Copșa Mică, with the flames reaching a height of 150 m (490 ft). It took almost 7 years for the authorities to find a way to extinguish the fire, while American specialists were also called upon. In the end, the fire was put out by military forces, who used 4,681 drilling mud wagons and 3,753 water wagons, the equivalent of a 126 km (78 mi) long train set. After the fire was extinguished, there was a work stoppage, due to the opposition of the military authorities to work in the gas zone; this was due to the danger of the fire rekindling and it being easily detectable by enemy aircraft (see Bombing of Romania in World War II). Operations to stop the eruption resumed after 1944 and the gas eruption was finally eliminated in 1947. The eruption and the fire at the Copșa Mică gas field lasted 11 years in all; the gas flow estimated to have been lost through this eruption is equivalent to half of what the whole of Romania consumes in a year.[10]
The 1933 fire at the gas field led to the creation of a carbon black factory at Copșa Mică.[10] The emissions from the Copșa Mică works permeated the area for nearly sixty years, leaving soot on homes, trees, animals, and everything else in the area. For many years, the town was best known for its status as the second most polluted one in Europe after Chernobyl.[11]
