Division of TAGRAS Holding Breaks Its Own Record for Hydraulic Fracturing Volume with 310 Tons of Proppant Injected
At Well No. 10000 of the Yuzhno-Balykskoye Field (Khanty-Mansi Autonomous Okrug), owned by RN-Yuganskneftegaz, the TAGRAS-RS division of TAGRAS Holding carried out a high-volume hydraulic fracturing (HF) operation with the injection of 310 tons of proppant.
A key factor in the success of the operation was the use of an innovative technology — cold-water HF, developed and implemented by the company in May 2025. The method allows the use of water at a temperature of approximately +15°C without preheating, significantly reducing preparation time and cutting costs.
Gulnaz Valiullina, HF Development Project Manager at TAGRAS-RS, stated:
“The technology eliminates additional expenses and accelerates the process by omitting fluid heating. This provides a significant economic benefit for both the service company and the client.”
The technology was first tested by the division at fields in the Volga-Ural region during 2021–2022 and demonstrated its effectiveness.
Technological highlights of the operation:
Reinforced pumping unit with a capacity of 2,500 HHP
Innovative fluid composition for formation protection
Real-time digital monitoring of the process
By the end of 2025, the company plans to conduct five more similar operations at Rosneft’s fields.
