Helium occurs in numerous natural gas fields in the Polish Lowland. Its content in the natural gas varies from 0.02 to 0.45%. The resources of helium were documented within 18 fields where its content in the natural gas is varying from 0.22% to 0.42%. These gas fields are situated in the Zielona Góra - Rawicz – Odolanów area (a southern part of the Fore-Sudetic Monocline) and related to the Rotliegend, Zechstein Limestone and Main Dolomite formations of the Permian.
Resources and output
The Minister of Climate and Environment approved in 2020 “The geological-investment documentation of the natural gas field Trzebusz”. In the documentation there were helium occurring in the field documented – the average content of this element in the gas is equal 0.246% of volume. The deposit is located in the north-western part of the Pomerania segment, within the Carboniferous sandstone formations. The remaining deposits with the documented helium, occur in the southern part of the Fore-Sudetic Monocline in the area of Zielona Góra – Rawicz – Odolanów – within the Rotliegend, Zechstein Limestone and Main Dolomite formations.
Table 1 shows the current state of development of helium resources.
In 2020, the recovery of helium from 10 fields was equal 0.71 million m3. The given volume does not include the recovery from the fields in which a helium admixture has not been documented. The total pure helium production by Polish Oil and Gas Company (POGC – in Polish PGNiG) – Odolanów Branch, recovered from the exploited natural gas in Poland, amounted to 2,922,188 m3 in 2020.
The figure below shows resources and production of helium in Poland in the years 1989-2020.
The prospective resources of helium, according to The balance of prospective mineral resources of Poland, amount to about 34.68 million m3 and occur within 30 natural gas fields in which helium has not been documented so far*). These are deposits located in the Polish Lowland, within the Paleozoic platform on the Fore-Sudetic Monocline. The gas-bearing horizon of the deposits is formed by Rotliegend, Zechstein Limestone and Main Dolomite formations. The natural gas occurring in these deposits is the free natural gas.
