Natural gas production
Natural gas extraction is a complex process that has continuously evolved over the decades. One of the primary methods used to extract natural gas is hydraulic fracturing, or fracking. This technique involves injecting water, sand, and chemicals into a wellbore at high pressure to fracture the rock and release the trapped gas.
However, natural gas is not just extracted from deep rock layers; it can also be found in significant quantities in gas fields and specific natural gas deposits. The technologies and methods employed vary depending on the geographic location and characteristics of the deposit, which presents a scientific and technical challenge for extraction.
Security of supply
Ensuring the security of natural gas supply is a crucial topic in energy policy and economy. It guarantees the uninterrupted flow and availability of natural gas for households, businesses, and industries.
The secure and uninterrupted supply of natural gas is of utmost importance in Europe, as many countries heavily rely on imports. Disruptions, whether caused by geopolitical tensions or technical issues, can have significant impacts on the energy market and the economy. Therefore, investments in infrastructure, gas storage, and diversifying sources of supply are crucial in order to maintain a stable and reliable gas supply.
The international natural gas market
The international natural gas market is a complex network that consists of producers, suppliers, and consumers, all of which are influenced by geopolitical, economic, and technological factors. In a globally interconnected world, where the demand and supply of energy are in constant flux, this market plays a crucial role in ensuring the global energy supply.
In the following, we will examine the main actors, dynamics, and challenges of this market in more detail and analyze their impact on Europe and the world.
The main actors
The international natural gas market is dominated by a number of key players that have a major influence on supply, demand, and pricing. Leading natural gas producers include countries such as Russia, Norway, the USA, and the Netherlands. In particular, Russia, often represented by its state-owned companies, is a primary supplier to many European countries. The Ukraine plays a critical role as a transit country for gas supply in Europe.
On the consumer side, Europe is at the forefront, with Germany, Italy, and France being among the largest importers. These countries, along with the operators of various multinational energy companies, play a significant role in shaping the dynamics and strategies in the global gas market.
Gas prices and trade
The prices of natural gas are influenced by numerous factors that impact both its supply and demand.
