Crude Oil and Gas
Crude Oil
Interesting facts about crude oil
History
Crude oil has been industrially extracted in Germany for more than 150 years. The successful oil well in Wietze near Celle in 1858/59 is generally recognised as being one of the first in the world. Crude oil production in Germany peaked in 1968 with an annual production of around 8 million tonnes. Proven and potential crude oil reserves in Germany were estimated to be around 27 million tonnes as of 1 January 2021. Most of the crude oil reserves are in the North German Basin, primarily in Schleswig-Holstein and Lower Saxony. At the end of 2020, there were 49 oil fields in production.
Economic importance
With a share of around 34% of primary energy consumption, crude oil is by far the most important energy source in Germany. In this context, fossil fuels with a share of 76% generally account for a much larger share than renewable forms of energy. In 2020, domestic oil production amounted to around 2% of Germany’s annual consumption and thus remained the same compared to the previous year. Germany is one of the world’s largest users of mineral oil, making it almost entirely dependent on importing crude oil and crude oil products. Imports of crude oil are, at around 83 million tonnes, slightly lower than in the previous year. These imports in total were valued at €23.1 billion and came from 32 countries (1), with 56% of the imported crude oil alone coming from Russia (28.2 million tonnes), Great Britain (9.6 million tonnes) and the US (9.4 million tonnes). Germany produced slightly less than 2 million tonnes of crude oil in 2020. The country’s share of global oil production amounted to approx. 0.04% in 2020. The value of crude oil produced in Germany in 2020 is estimated to be €528 million, which represents 0.01% of GDP. Crude oil accounted for around 4.5% of the total value of natural resources produced in Germany in 2020. In terms of economic significance, crude oil thus ranked third behind lignite and natural gas in the list of fossil energy resources produced in Germany and in seventh place out of all natural resources extracted nationwide. In a 2020 international comparison of crude oil-producing countries, Germany was in 58th place (1970: 26th place). At the end of 2020, 2,008 persons were employed in oil production in Germany (2).
Extraction
In 2020, 49 oil fields were in production in Germany. These fields extract oil by means of some 743 production wells in drilling installations (onshore) and production platforms (offshore). In 2020, the oilfields of Schleswig-Holstein and Lower Saxony yielded almost 90% of the total German production. The remaining quantity was mainly produced in the Federal States of Rhineland-Palatinate and Bavaria, together with very low production levels in Hamburg, Brandenburg and Mecklenburg-Western Pomerania. The largest German crude oil field is the Heide-Mittelplate I field in the Schleswig-Holstein Wadden Sea (Wattenmeer) National Park. It has been developed since 1987 by a drilling and production island and by oil well facilities on the mainland. This oil field accounted for more than half of Germany’s total crude oil production in 2020.
Uses
Crude oil is a fossil energy source. It is primarily used as a fuel for vehicular transportation and to heat buildings. Over the last few years, oil has accounted for 94% of energy consumption in the transport sector. Besides, oil makes up around 23.4% of the energy used for heating buildings. A particularly heavy user of crude oil is the chemical industry for processes such as the manufacture of plastics, paints, foam, washing detergents, medicines, lubricants and cosmetics.
Natural gas
Interesting facts about natural gas
History
In 1910, natural gas was found in Neuengamme (which is a district of Hamburg today) when drilling for water. The industrial production of natural gas started in 1913. However, natural gas production in Germany remained minimal until the end of the 1960s, with only a1 % share of the primary energy consumption in Germany (West). The oil crises of the 1970s focused increased attention on the consumption of energy and the need for the development of energy sources.
Domestic production grew with the discovery of large gas deposits on the German-Dutch border and the increasing conversion of town and coke-oven gas to natural gas. This was accompanied by a steady expansion of the gas infrastructure (from 12 to approx. 20 billion m³ (Vn) (3) of raw gas between 1970 and 2005). In 2005, domestic natural gas production covered around 25 % of German natural gas consumption. Since then, however, production has declined. The safe and probable reserves of natural gas are also declining. These amounted to around 43 billion m³ (Vn) as of 1 January 2020. The decline in natural gas reserves and production is mainly due to the increasing depletion of the deposits and the resulting natural decline in extraction. There have been no significant new discoveries in recent years. A legislative process lasting several years was also responsible for the decline in reserves; during this process, the topics discussed included future requirements for the use of fracking technology, which led to new legislation in 2016.
Economic importance
Natural gas is still the second most important source of energy in Germany with a share of around 26% of primary energy consumption. In 2020, natural gas production in Germany amounted to around 5.7 billion m³ (Vn) of raw gas, covering only about 5% of domestic natural gas consumption which decreased by approx. 1.3 % in 2020. In 2020, 1,674 TWh of natural gas valued at €18 billion were imported. The imported gas originated in Russia/CIS (1,121 TWh), Norway (349 TWh), the Netherlands (194 TWh) and Belgium (9.6 TWh). There was a very slight reduction in imports (–1.7 %) compared to the previous year. However, a considerable proportion of the natural gas imported was reexported to neighbouring European countries (814 TWh). In terms of the economic significance of domestically produced natural gas, Germany ranked number 48 in the comparison of all natural-gas-producing countries in 2020. The country’s share of global natural gas production amounted to just under 0.15% in 2020. The value of the natural gas extracted in 2020 amounted to an estimated €0.75 billion. That is equivalent to about 0.02% of GDP. Natural gas accounted for around 7 % of the total value of natural resources produced in Germany in 2020. At the end of 2020, 1,275 persons were employed in the German production of natural gas. (4)
Extraction
Around 94% of German natural gas was extracted in Lower Saxony in 2020. Other Federal States (Saxony-Anhalt, Schleswig-Holstein, Thuringia and Bavaria) contributed only marginally to the total production. 406 production wells extracted natural gas on 73 gas fields. The A6/B4 natural gas field in the “Entenschnabel” (duckbill) – an economic zone in the German Bight (North Sea) – is the only German offshore gas field. 2020 was the last time natural gas production was reported from this field and the natural gas field is now considered depleted. Since 1974, 9.5 billion m³ of raw gas and 813,000 tonnes of natural gas condensate have been produced from this gas field. Like crude oil, natural gas occurs in underground deposits. Similar to the exploration of crude oil, the exploration of natural gas takes place primarily through seismic surveys and exploration drilling. Gas extraction takes place through a borehole stabilised with cement and steel and a riser pipe is then inserted through the hole.
In addition to the development of conventional deposits, the development of non-conventional natural gas deposits is conceivable. Unconventional deposits include natural gas deposits in shale, clay, marl and coal seam rock, the development of which requires the use of “hydraulic fracturing” or “fracking” for short. “Fracking” involves injecting a suspension (water, proppants and additives) and the resulting increase in pressure to create small cracks in the rock containing the natural gas in a controlled manner. This process releases the gas so that it can be brought to the surface through the drilling pipes.
“Fracking” in Germany has been used for many decades in the development of conventional deposits, especially in dense sandstones (mostly at greater depths) and has been tried and tested for many years. However, the use of fracking for the commercial development of shale, clay, marl and coal seam rock (i.e. unconventional deposits) is not permitted in Germany until further notice. (5) The German parliament has not yet made use of the opportunity to review the ban on the basis of the report of the Fracking Expert Commission presented in 2021. The topic of fracking continues to be discussed very controversially in Germany.
Uses
As a fossil fuel, natural gas is mainly used in industry (36%) and in private households (31%, mainly for heating). In addition, it is used to generate electricity (14%) in the trade, commerce and services sectors (12%) and in district heating/cooling (including combined heat and power plants; 7%). In transport, natural gas plays a very minor role as a fuel at 0.2%. Natural gas also other uses – as a reactant in chemical processes (e.g. for ammonia synthesis in the Haber-Bosch process (nitrogen fertiliser), for iron ore reduction in the blast furnace process but particularly in the production of hydrogen through steam reforming.
