The Law on Subsoil dictates that ownership of the subsoil belongs to the government, provided that individual rights and legal entities are respected. Subsurface use is to be based on a number of principles, including ensuring rational, complex and safe use of subsoil and environmental protection. The regulation also governs licensing pertaining to oil and gas operations, including exploration, extraction and production, as well as processing and transportation via pipelines. Furthermore, it states that subsoil operations, including operations in oil-gas fields, may be restricted or prohibited where these operations may cause a threat to national security, to the lives and health of people, and the environment. It also has provisions regarding the payment of royalties and taxes related to the use of the subsoil and mineral resources.
