Moscow, January 28 - Neftegaz.RU. Gazprom Neft has successfully tested an enhanced oil recovery (EOR) technique at the Bazhenov Formation, using a xanthan-gum-based fracking fluid.
Using this new technology has facilitated a 66% increase in hydrocarbon production at those wells on which it was tested.
This new mixture has demonstrated its high effectiveness under 19-stage high-speed hydraulic fracturing, involving the injection of 150 tons of proppant at each stage, with a flow rate of more than 12 cu m per minute.
Undertaken at the Bazhenov Formation for the 1st time, this represents a unique operation for the industry.
The Bazhen Technology Centre has, so far, tested the new mixture at 2 wells, and is currently testing it at a third. A decision on rolling-out this technology will be taken following an assessment of the economic and productive benefits of well stimulation.
«The future of the oil and gas industry is directly linked to developing non-traditional hydrocarbon reserves - the world’s largest source of which is the Bazhenov Formation.
One of the key tools in developing these is high-tech fracking. Improvements here are bringing us closer to developing a viable technology for producing Bazhenov oil.
The innovative solutions developed through this work are also helping to develop the industry, and are likely to be in considerable demand in developing fields throughout Russia», Kirill Strizhnev CEO, Bazhen Technology Centre.
