ООО Gazprom podzemremont Urengoy is the most major company within OAO Gazprom, which  specializes in well workover at Western Siberia fields  situated mostly on the territory of Yamal-Nenets Autonomous Okrug. Increase of service life of producing wells by enhancement of well workover efficiency is one of the company priorities. The company pays special attention to development and implementation of advanced technologies and special techniques, as well as organization of new forms of well workover operations.

 

In order to periodically perform timely well workover one has to use new reliable methods and technologies of well maintenance that need little time and financial efforts, as well as low labour costs.

World experience shows that in present-day conditions the problem of well workover efficiency increase should be solved in the framework of environmental safety concept by minimizing the negative influence of well workover companies on the environment. Since 1999, according to the decision of OAO Gazprom, the utilization of coiled tubing technologies, which showed high cost efficiency, has started at Urengoi and Yamburg fields. Utilization of coiled tubing units extended technological possibilities in the area of well workover, having allowed to substantially increase the variety of well workover operations and the volume of these operations.

Today the development of several low-cost technologies, which reduce well workover expenses and duration, results in the increase of coiled tubing technologies applications with respect to other types of well workover methods.
