The article describes the experience of the development of information technology for the block of well operations, namely the creation of the information telemetry system Well Workover, an overview of the existing problems and ways to solve them. In turn, the characteristics of the main elements of the information system are described, its functional capabilities are described at all levels of management of workover operations (planning of workover operations; monitoring of current performance of the workover rig; generation of reporting and database; analysis of the effectiveness of workover operations), information flows generated by the system are shown. The first results of the pilot operation of the telemetry system Well Workover have been summed up, the positive results achieved; further steps are indicated for the development of the system and for creating a single information space for planning, registration, control and managing well operations.
