The Zau de Câmpie gas field is a natural gas field located in Zau de Câmpie, Mureș County. It was discovered in 1914, when the first gas extraction fields were created, supplying Târnăveni and Târgu Mureș with natural gas. [1]: 37 The Zau de Câmpie gas field was developed by Romgaz. It began production in 1920 and produces natural gas and condensates.
Romania has important quantities of methane gas reserves, especially in the Transylvanian Depression, south and north of the Mureș River, at Puini, Zau de Câmpie, Luduș, Șincai, Bazna, Nadeș, etc, [2]: 76 where about 75% of the 0.1×10 12 m3 (3.5×10 12 cu ft) of the country's natural gas reserves are located. [3] The gas fields in Mureș County alone (the main ones being at Sărmașu, Sărmășel, Ulieș, Sânmărtin, Crăiești, Zau de Câmpie, and Luduș) provide 60% of the total extracted in Romania. [4]: 102 The Transylvanian Basin is the geological unit with the largest and most natural gas reserves in Romania; it is the single sediment basin in the country and among the few in the world where only gas accumulations, mainly methane, have been discovered. [5]
In 1970, Romania ranked fourth in the world and second in Europe in the size of its natural gas deposits; [6]: 214 by 2016, it ranked third in Europe after the Netherlands and the United Kingdom. [3] The United States Geological Survey's 2000 World Energy assessment ranked the Transylvanian Basin region as the 56th largest in the world (exclusive of the United States), with 0.2% of the world's oil and gas resources, based on volume of reserves plus cumulative production. [7]
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. The oldest deposits exploited by Romgaz are in Mureș County, where gas has been extracted since 1913. [8] Deposits of methane gas occur in three main areas; the first are is in the northwest and includes the Sărmașel, Zau de Câmpie, and Șincai gas fields. [6]: 216 The North Group contains 31 gas fields located to the north of the Mureș River. These are found under the form of dome traps. Representative for this group are the Sărmașel, Grebenișu de Câmpie, Zau de Câmpie, and Țaga gas fields. [5]
The first natural gas deposit in Romania was discovered in 1909, in Sărmașel, about 22 km (14 mi) north of Zau de Câmpie. In 1913, the first production of methane gas was recorded, of 113,000 m3 (4,000,000 cu ft), from the drilling site at the Sărmașel gas field. [8] That year, the local Greek Catholic priest announced to the Zau de Câmpie community that they will start "to dig for gas, in the form of the one from Sărmașel," on a 2,400 m2 (26,000 sq ft) plot of land belonging to the church. [9] Besides Sărmășel and Zau de Câmpie, other gas fields developed in the area were the ones at Deleni, Nadeș, Bazna, and Șincai, followed later by those at Bogata, Ilimbav, Miercurea Nirajului, Tăuni, Teleac, and Filitelnic. [10]
The first geological study of the Zau de Câmpie gas dome (in connection with the classification of mud volcanoes and salt mines in the Transylvanian Plain) was done by Augustin Vancea in his 1929 Ph.D. dissertation. [11] [12]: 5 According to a CIA report from 1948 (quoting an article from the communist party organ Scînteia), the Zau de Câmpie gas field was under geological study since 1935, and exploration was begun in 1948, when an important deposit of gas was discovered at a depth of 633 m (2,077 ft). Concomitantly, the Ceanu Mare– Cluj pipeline was being constructed, with the Zau de Câmpie wells due to supply natural gas to the city of Cluj. [13]: 2
The gas produced at Zau de Câmpie and in the surrounding area is considered to be the purest one; it consists of dry gases, usually made of 99% methane, with the rest hydrocarbons ( ethane, propane, and butane). [14]: 2 [15] It currently uses a type C 25.1 Thomassen compressor unit to compress the gas extracted in the field. [16]
In 2009, the total proven reserves of the Zau de Câmpie gas field were around 416 billion cubic feet (12 km³), and production was slated to be around 3.6 million cubic feet/day (0.1×105 m³) in 2010. [17] By January 2017, there were 62 active drilling rigs at the site; the reserves of the Zau de Câmpie– Șăulia gas field were estimated at 2.47×10 9 m3 (87×10 9 cu ft), and were slated to be depleted by 2029. [18] In July 2018, the Romanian Agency for Mineral Resources announced that the Romgaz lease of the gas field has been extended until 2027. [19] [20]

The Târnăveni gas field natural gas field is located near the city of Târnăveni in Mureș County. It was discovered in 1950 and developed by Romgaz. It began production in 1955 and produces natural gas and condensates. The total proven reserves of the Târnăveni gas field are around 418 billion cubic feet (12 km³) and production is slated to be around 55 million cubic feet/day (1.55×105m³) in 2010. [1]
The first derrick used to extract gas at Târnăveni was located in the village of Botorca [2] (now part of the city). In 1922, hydrogen was produced for the first time in Romania at the Nitrogen Plant in Târnăveni, using water and natural gas. [3] [4]
According to a CIA report from September 1950, the Târnăveni gas field supplied natural gas to the Târnăveni Nitrogen Plant, the oldest and largest chemical factory in Romania. The plant was the first large installation in Romania that used natural gas to derive its necessary energy. The gas pipeline is 25 km (16 mi) long and comes from the gas field, which is located south of the city. [5] In a report from a week later, the CIA noted that a gas pipeline from Târnăveni to Kiev had been constructed. [6]

The Bobocu gas field is a natural gas field in Bobocu village, Cochirleanca Commune, Buzău County. It was discovered in 1966 and first developed by Romgaz, the Romanian national gas company, but was abandoned in 1995 due to a sand influx in well boreholes. The field was acquired by Zeta Petroleum in 1998. It will begin production in 2011 and will produce natural gas and condensates. The total proven reserves of the Bobocu gas field are around 147 billion cubic feet (4.2 km³), and production is slated to be around 25 million cubic feet/day (0.71×105m³) in 2011. [1] [2] [3]
In 2012, Zeta Petroleum spudded the first well at the Bobocu gas field, with a targeted depth of 2,700 m (8,900 ft). The well lies in a crestal location at the center of the concession and is targeting two delta lobes in the Pontian interval that were earlier identified through amplitude variations in the 3D seismic survey. [4] In 2016, the company decided to give up on its holdings at Bobocu. [5]
In 2020, the license to exploit the gas perimeter from Bobocu was bought by the Dutch company Lalea Energy. It subsequently re-entered the portfolio of the Canadian firm Claren Energy, and then was sold to Blueray Energies Romania. [6] [7]

The Zau de Câmpie gas field is a natural gas field located in Zau de Câmpie, Mureș County. It was discovered in 1914, when the first gas extraction fields were created, supplying Târnăveni and Târgu Mureș with natural gas. [1]: 37 The Zau de Câmpie gas field was developed by Romgaz. It began production in 1920 and produces natural gas and condensates.
Romania has important quantities of methane gas reserves, especially in the Transylvanian Depression, south and north of the Mureș River, at Puini, Zau de Câmpie, Luduș, Șincai, Bazna, Nadeș, etc, [2]: 76 where about 75% of the 0.1×10 12 m3 (3.5×10 12 cu ft) of the country's natural gas reserves are located. [3] The gas fields in Mureș County alone (the main ones being at Sărmașu, Sărmășel, Ulieș, Sânmărtin, Crăiești, Zau de Câmpie, and Luduș) provide 60% of the total extracted in Romania. [4]: 102 The Transylvanian Basin is the geological unit with the largest and most natural gas reserves in Romania; it is the single sediment basin in the country and among the few in the world where only gas accumulations, mainly methane, have been discovered. [5]
In 1970, Romania ranked fourth in the world and second in Europe in the size of its natural gas deposits; [6]: 214 by 2016, it ranked third in Europe after the Netherlands and the United Kingdom. [3] The United States Geological Survey's 2000 World Energy assessment ranked the Transylvanian Basin region as the 56th largest in the world (exclusive of the United States), with 0.2% of the world's oil and gas resources, based on volume of reserves plus cumulative production. [7]
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. The oldest deposits exploited by Romgaz are in Mureș County, where gas has been extracted since 1913. [8] Deposits of methane gas occur in three main areas; the first are is in the northwest and includes the Sărmașel, Zau de Câmpie, and Șincai gas fields. [6]: 216 The North Group contains 31 gas fields located to the north of the Mureș River. These are found under the form of dome traps. Representative for this group are the Sărmașel, Grebenișu de Câmpie, Zau de Câmpie, and Țaga gas fields. [5]
The first natural gas deposit in Romania was discovered in 1909, in Sărmașel, about 22 km (14 mi) north of Zau de Câmpie. In 1913, the first production of methane gas was recorded, of 113,000 m3 (4,000,000 cu ft), from the drilling site at the Sărmașel gas field. [8] That year, the local Greek Catholic priest announced to the Zau de Câmpie community that they will start "to dig for gas, in the form of the one from Sărmașel," on a 2,400 m2 (26,000 sq ft) plot of land belonging to the church. [9] Besides Sărmășel and Zau de Câmpie, other gas fields developed in the area were the ones at Deleni, Nadeș, Bazna, and Șincai, followed later by those at Bogata, Ilimbav, Miercurea Nirajului, Tăuni, Teleac, and Filitelnic. [10]
The first geological study of the Zau de Câmpie gas dome (in connection with the classification of mud volcanoes and salt mines in the Transylvanian Plain) was done by Augustin Vancea in his 1929 Ph.D. dissertation. [11] [12]: 5 According to a CIA report from 1948 (quoting an article from the communist party organ Scînteia), the Zau de Câmpie gas field was under geological study since 1935, and exploration was begun in 1948, when an important deposit of gas was discovered at a depth of 633 m (2,077 ft). Concomitantly, the Ceanu Mare– Cluj pipeline was being constructed, with the Zau de Câmpie wells due to supply natural gas to the city of Cluj. [13]: 2
The gas produced at Zau de Câmpie and in the surrounding area is considered to be the purest one; it consists of dry gases, usually made of 99% methane, with the rest hydrocarbons ( ethane, propane, and butane). [14]: 2 [15] It currently uses a type C 25.1 Thomassen compressor unit to compress the gas extracted in the field. [16]
In 2009, the total proven reserves of the Zau de Câmpie gas field were around 416 billion cubic feet (12 km³), and production was slated to be around 3.6 million cubic feet/day (0.1×105 m³) in 2010. [17] By January 2017, there were 62 active drilling rigs at the site; the reserves of the Zau de Câmpie– Șăulia gas field were estimated at 2.47×10 9 m3 (87×10 9 cu ft), and were slated to be depleted by 2029. [18] In July 2018, the Romanian Agency for Mineral Resources announced that the Romgaz lease of the gas field has been extended until 2027. [19] [20]

The Târnăveni gas field natural gas field is located near the city of Târnăveni in Mureș County. It was discovered in 1950 and developed by Romgaz. It began production in 1955 and produces natural gas and condensates. The total proven reserves of the Târnăveni gas field are around 418 billion cubic feet (12 km³) and production is slated to be around 55 million cubic feet/day (1.55×105m³) in 2010. [1]
The first derrick used to extract gas at Târnăveni was located in the village of Botorca [2] (now part of the city). In 1922, hydrogen was produced for the first time in Romania at the Nitrogen Plant in Târnăveni, using water and natural gas. [3] [4]
According to a CIA report from September 1950, the Târnăveni gas field supplied natural gas to the Târnăveni Nitrogen Plant, the oldest and largest chemical factory in Romania. The plant was the first large installation in Romania that used natural gas to derive its necessary energy. The gas pipeline is 25 km (16 mi) long and comes from the gas field, which is located south of the city. [5] In a report from a week later, the CIA noted that a gas pipeline from Târnăveni to Kiev had been constructed. [6]

The Bobocu gas field is a natural gas field in Bobocu village, Cochirleanca Commune, Buzău County. It was discovered in 1966 and first developed by Romgaz, the Romanian national gas company, but was abandoned in 1995 due to a sand influx in well boreholes. The field was acquired by Zeta Petroleum in 1998. It will begin production in 2011 and will produce natural gas and condensates. The total proven reserves of the Bobocu gas field are around 147 billion cubic feet (4.2 km³), and production is slated to be around 25 million cubic feet/day (0.71×105m³) in 2011. [1] [2] [3]
In 2012, Zeta Petroleum spudded the first well at the Bobocu gas field, with a targeted depth of 2,700 m (8,900 ft). The well lies in a crestal location at the center of the concession and is targeting two delta lobes in the Pontian interval that were earlier identified through amplitude variations in the 3D seismic survey. [4] In 2016, the company decided to give up on its holdings at Bobocu. [5]
In 2020, the license to exploit the gas perimeter from Bobocu was bought by the Dutch company Lalea Energy. It subsequently re-entered the portfolio of the Canadian firm Claren Energy, and then was sold to Blueray Energies Romania. [6] [7]
