Horizontal well multi-stage fracturing- Gazprom neft JSC experience

Authors: A.N. Govzich, A.V. Bilinchuk (Gazprom Neft JSC, RF, Saint-Petersburg), I.G. Fajzullin (Gazpromneft NTC LLC, RF, Saint-Petersburg)

Key words: multi-stage fracturing, horizontal well, coil tubing, well completion.

This article is devoted to the implementation of new technology of well stimulation on the fields of Gazprom Neft with low filtration properties and is aimed to an effective oil production rate achievement. This work is about approaches in choosing the strategy of the involvement reserves hard to recover to the development; applicable technological solutions which are being focused on lateral drilling attended by some hydraulic fracturing, which reduces the number of wells; drilling with retaining reservoir sweep and achievement of planned oil recovery index. In conclusion are presented the results of pilot works and possible ways of optimization.
