RN-Purneftegaz started using composite shutters made in Russia
RN-Purneftegaz, which is part of the oil production complex Rosneft, switched to using the latest Russian-made composite packers during the workover of the well. The effect of the introduction of this technology is estimated at 50 million rubles per year. On this subject said in Rosneft’s message.
Packers are used to permanently or temporarily isolate one area of the wellbore from another during well testing and workover, and during hydraulic fracturing.
The use of domestic composite plugs instead of cast-aluminum plugs, which were used before, reduced the repair time of the well by an average of 30%, as well as increased work efficiency
