Specialists of RN-Yuganskneftegaz, the Company’s key production asset, extracted more than 100 tons of oil from one well of the Pravdinskoye field in one day. At present, this is the best result achieved when launching horizontal wells at fields with similar geological conditions. The record was achieved thanks to a new method of hydraulic fracturing (HF), developed by scientists from the corporate research institute in Ufa.
The new method of hydraulic fracturing is carried out in several stages, during which low-viscosity and high-viscosity fluids with large-fraction proppant are pumped into the formation alternately. The technology allows creating a hydraulic fracture up to 600 meters long, while increasing its conductivity and ensuring effective oil flow from the formation into the well.
Hydraulic fracturing is a key technology for intensifying oil production. The Company’s development will significantly increase productivity and production from low-permeability reservoirs of the Bazhenov* and Achimov** formations, as well as their analogues.
*The Bazhenov Formation formed in Western Siberia from deep-sea sedimentary rocks at the end of the Jurassic and the beginning of the Cretaceous period about 145 million years ago. As a rule, it lies at a depth of 2.5-3 km and has a thickness of about 30 meters. **The Achimov Formation is a deposit in Western Siberia, lying at depths from 2.5 to 4 km in the lower part of the Cretaceous deposits above the Bazhenov Formation.
