About company

About company

"The Plant Neftegazmash" LLC is a producer of high-tech drilling and petroleum engineering equipment for oil-and-gas industry.

Owning the necessary production facilities and highly qualified personnel, the plant also carries out maintenance and overhaul of the drilling and oil-and-gas machinery, produced domestically and abroad.

"The Plant Neftegazmash" LLC offers to customers complex decisions for drilling companies: from the equipment designing to final putting it into operation, our services include supervision of erection, starting up and adjustment, warranty and post-warranty service. The enterprise also produces import-substituting equipment applying modern technologies.

Operating more than a half of a century in the area of production and maintenance of the drilling equipment and special-purpose machinery, as well as supplying spare parts for them, the company deserved the reputation of a reliable and stable partner, able to meet customers' requirements and to adapt the production both for repetition work and individual projects.


1960 is considered as the year of the plant foundation, when the Ministry of the Oil industry created Machinery and Repair plant for the needs of the field. The plant provided companies of the oil-and-gas complex with drilling and petroleum equipment, its components, also repairing and servicing drilling equipment. The association "Nizbnevozhskneft" had been the general customer of the plant for years.

Within its long history the enterprise changed several names, and finally it was named "The Plant Neftegazmash" in 2005. In that very moment some serious changes took place in the company's management, that allowed it to enter a new level of the more critical importance in the industry.

2005 is the year of the second birth for the company. Registered on 26th of December 2005 in Volgograd city, Limited Liability Company "The Plant Neftegazmash" became the assign of the "Machinery and Repair plant".

Technical and production possibilities of the company, highly qualified personnel with huge working experience, the equipment renewal and introduction of advanced technologies allowed to scale up the operation process and the range of services.
Nowadays the plant keeps on meeting the increasing demand in drilling equipment supply and production on the market, and it still works in the area of technical service, maintenance and overhaul.
