ABSTRACT
The first oil well in the world was drilled in Bibiheybet in 1846 by industrial method (mechanical drilling) and later by drilling in Balakhani in 1871 using impact technology, it turned Azerbaijan into the center of oil production. As a result of the analysis of the country's oil exploration, it was determined that during the past years, over 30,000 oil and gas wells in the land and sea areas have been drilled, and exploited and in the end, their activities were suspended, conserved, or canceled. Currently, the stock of wells in operation is slightly more than 6000. In these processes, environmental imbalances in the areas of oil and gas mines, and pollution of land and water areas, as well as led to the occurrence of serious deviations in the underground.
On the other hand, the technology of decommissioning expired wells requires updating, where not only the cleaning of the polluted oil areas but also the solution to the problems related to the recultivation of the subsoil in the zones are of great importance.
Despite a wide range of scientific research works that have been carried out in the direction of the development of existing methods of decommissioning wells, the issue of the full assurance of the hermeticity of decommissioned wells is considered to be a problem.
On the other hand, the corrosion of protective belts, the absence of cement stone rings behind the belt, as well as the collapse of cement bridges lead to an increase in the probability of the formation of a connection between the productive layers and the ground surface, causing residual oil and gas to flow to the surface in later decommissioned wells [1-3].
For this reason, the presented article is dedicated to the analysis of the current situation of oil well cancellation, restoration, and subsoil recultivation problems and the development of relevant recommendations.
Keywords: oil and gas mines, canceled wells, environmental hazard, underground reclamation, hermeticity.
