Oil and gas field service

Wireline well services are carried out by two branches located in Western and Eastern Siberia. Nefteyugansk branch with the personnel of 350 people is located in Nefteyugansk city and includes 35 production crews. Its main customer is LLC «RN-Yuganskneftegas». Oil and gas field monitoring is conducted in Priobsk, Pravdinsk, East Pravdinsk, West Salymsk, Petelinsk, Malobalyksk, Central Balyksk, South Balyksk, Efremovsk, Ugutsk, Kinyaminsk, Fainsk, Mamontovsk, Maysk, Teplovsk, Ombinsk, East Siberian fields. 

Nefteyugansk branch also includes Buzulukskiy geophysical expedition, which began its work since the end of the 2016. Expedition, numbering 80 people and based in the city of Buzuluk, is composed of 6 PEO production batches. Perforating-explosive operations are conducted mainly at the fields of JSC «Orenburgneft» in the Orenburg and Samara regions.

Krasnoyarsk branch with its personnel of 60 people and 10 productive crews is located in Vankorsk field. Administrative and managerial staff is in Krasnoyarsk city. Its main customer is CJSC «Vankorneft» and CJSC «East Siberian oil company». Oil and gas field monitoring is conducted mainly in Vankorsk and Yurubcheno-Tohomsk fields.

Wireline well services are conducted in all weather conditions and with up-to-date equipment. Data transmission is performed via satellite-delivered channels, and is followed by immediate data interpretation and decision issue.
