Repair of wells  wells is an essential condition to ensure the facilities full operation in oil and gas industry. A malfunction of the main wells is caused by many reasons, leading to a significant reduction in its flow rate or to a full shutdown of its operation. Production reduction or shutdown can be caused by failure of surface or underground equipment, changes in reservoir conditions, the shutdown of gas or power supply, stop of the pumping, transportation of liquids to the surface other factors.

Therefore, a prompt repair of wells is necessary to prevent the equipment from the downtime. The frequency and the relative duration of the overhaul are estimatedwith some indicators that characterize the organization and technology of oil production.
