Abstract: Reliability is a desirable property of a completed well including offshore. On practice, the concept of "well reliability"is often connected with the reliability of its supporting structure - support. This is true if strength issues are considered, requiring the determination of the values of the loads that the main power element of the well can work on. And this is not true if the reliability of a well is understood as its long-term and safe operation, since in this case it is necessary to take into account the objects that form the system of well reliability. The algorithm for determining the reliability of completed wells is shown using the example of underground gas storage (UGS) wells. Determination of reliability has a significant economic component, since it establishes such indicators of wells as gamma-percentage service life and extended (within the residual service life) safe operation period. If these indicators are not defined as indicators of well reliability, then they are assigned. As a rule, the assigned dates are shorter than the actual ones and this leads to an increase in well maintenance costs, in particular, due to the number of industrial safety examinations that must be carried out at the end of the assigned period of time regardless of the technical condition of the wells.
