EXPERIENCE

Western Siberia
Achimov formation
Challenges

  • Low permeability
  • Uncertainties of geological and geomechanical properties
  • Drilling Problems

Results

  • First multi-stage fracturing horizontal well (TAML-3) modeling
  • Selection of the optimal hydraulic fracturing technology
  • 100% increase in initial oil production rates of planned wells
Western Siberia
Water cut level and HF treatment
Challenges

  • Ultra low permeability
  • High water cut level
  • High rates of production decline

Results

  • Decrease in flow rates decline from 30-45% to 7-10%
  • Water cut reduction from ~ 70% to ~ 10%
  • Reduction in geological problems and uncontrolled events
Western Siberia
Bazhenov formation
Challenges

  • Heterogeneity in reservoir properties distribution
  • Zones with natural fracturing
  • Low oil production rates

Results

  • Successful realization of hydraulic fracturing design
  • Starting oil production rates increases by 40%
  • Effectively realization of comprehensive approach for development of oilfiel
