földgázkészletekben

földgázkészletekben refers to natural gas reserves. These are quantities of natural gas that are known to exist and can be economically recovered with current technology and price levels. Natural gas is a fossil fuel formed over millions of years from the remains of ancient organisms. It is primarily composed of methane, but also contains varying amounts of other hydrocarbons and non-hydrocarbon gases.

The assessment of natural gas reserves is a complex process involving geological surveys, drilling, and sophisticated modeling techniques. Reserves are typically categorized into proved, probable, and possible reserves. Proved reserves are those that can be estimated with a high degree of confidence to be recoverable. Probable reserves have a lower confidence level, while possible reserves are even more speculative.

Global natural gas reserves are distributed unevenly across the world. Major reserves are found in countries like Russia, Iran, Qatar, the United States, and Turkmenistan. The extraction of natural gas from these reserves can occur through conventional methods, such as drilling into porous rock formations, or through unconventional methods, like hydraulic fracturing (fracking) of shale gas formations. The ongoing exploration and technological advancements continue to influence the estimates and accessibility of these vital energy resources.
