This article focuses on the creation of biogas by using domestic and industrial wastes reserves in the near-decommissioned oil and gas fields in the near future The main focus is on the gas generation process through including some technologies related to that, namely; main means for gas production (industrial and domestic wastes that decompose relatively quickly), the natural state of the gas and the effects of ambience changes were gotten based on (natural atmospheric pressure, temperature, and other additional factors that affect it). In general, biogas is formed as a result of anaerobic decomposition, and any decomposing product can be used in the process. In addition to this, all small factors namely some additional pressure in condition and temperature changes based situation and also existence of possibility of lasting control of the ambience will find own solution (In addition, all the small factors, such as the variability of some additional pressures and temperatures in the condition for the existent ambience and the possibility of the process escaping control, are also addressed.). The solution to some of the most serious issues to be addressed in the article is based on the example of the Republic of Uzbekistan, ie the geological conditions of the area, the total volume of landfills in the area and the status, class and total volume of waste there (condition of existing oil-gas deposits and its service life) , whereas, the approximate size of the Buzakhur field in the Bukhara-Khiva oil and gas region and the landfill in the Ahangaron district of the Tashkent region are cited as biogas reactors and raw materials respectively.

It is also most important to prevent immediately pollution of the environment, which is one of the main problems not only in Uzbekistan but also around the world, and to create a new stage of gas reserves, one of the natural resources. In this case, we can practice this theory not only to one city or state, but also to the whole world. It should be noted that today the number of household waste and their landfills is growing by the seconds, and their reduction is one of the most important topics that has crucial reason for everyone in the world. If the solution to this problem is one solution to waste problem, the creation of natural gas reserves using waste efficiently is a common and effective solution to the most pressing issues
