Annotation:

The problems related to the lack of accounting and control of oil and gas passive wells that are in a state of conservation, liquidation or waiting for liquidation, both on the part of the subsurface user and on the part of regulatory authorities, are disclosed. They account for about 20 % of the total number of drilled wells in Russia’s largest oil and gas fields. Information on accidents and causes at passive wells is presented. Based on the methodology for assessing the danger of passive wells, 5 hazard levels have been established. Of the 111 analyzed passive oil and gas wells in the fields of the Ural-Volga region, Western Siberia, Eastern Siberia, etc. It was found that 43 % are classified as high and extremely high danger levels and only 4 % are classified as a condition striving for safety. The advantages of introducing a methodology for assessing the danger of passive wells are presented, as well as characteristics of improving the elements of the industrial safety management system of an oil and gas production organization, among the objects of which are passive wells.
