The stadial structure of the formation of technogeosystems of oil and gas fields (TGSOGF) are characterized based on field and laboratory studies using remote sensing data from 12 key study plots within oil and gas fields in the Volga–Ural steppe region. TGSOGF is understood as a complete set of modified natural components and technological facilities that function as a whole during the development of an oil and gas field. Two main principles of the formation and functioning of a TGSOGF are distinguished. The first principle implies the temporal stadiality of development, determined by the period of field development and by the level (variety) of technogenic load on the landscape. The other principle is the reversible and irreversible transformation of landscape components, leading to changes in mutual physical-energy connections of its vertical and horizontal structures. The random diffuse-linear distribution of structural links of oil and gas fields forms a specific space of technogenic influence, which is characterized by the overlap, intersection, and combination of impact zones of oil and gas production facilities. There are five stages of transformation of the initial landscape with varying degrees of involvement of components in the transformation process. The initial landscape structure is formed from a technogenic block, including units with the irreversible introduction of structures of liquidated and/or temporarily abandoned wells at the final stage of field development. This results in the manifestation of equifinality: the completion of the oil and gas production process becomes equivalent for different landscapes and the natural invariant is replaced by the natural-technogenic one. Analysis of the features of oil and gas fields and determination of patterns of their functioning gave rise to the proposed concept of formation of a TGSOGF and made it possible to rationalize the optimization of the environmental management of oil and gas fields, taking into account the systematic principles of TGSOGF development and stadiality.
