Implementation of channel fracturing enhanced by rod-shaped proppant brings substantial value for depleted Devonian formations in the Orenburg region of Russia. Highly conductive channels inside the proppant pack significantly minimize the influence of multiphase and non-Darcy flow on overall production. The use of rod-shaped proppant in the final stage provides the highest possible conductivity in the critical near-wellbore region and eliminates the potential problem of proppant flowback.
Introduction
Fracturing is a standard completion method for all wells producing from Devonian formations in the Orenburg region of Russia’s Volga-Urals basin. Experience has shown that these fracturing treatments usually have some specific differences from fracturing in other parts of Russia.
