Rosneft for the First Time in the World Conducted Hydraulic Fracturing in Sandstones Using a Synthetic Polymer-Based Fluid
Specialists of JSC NK Kondaneft, a subsidiary of Rosneft, for the first time in the world performed hydraulic fracturing in sandstones using a fluid based on a synthetic polymer. An innovative solution allows to increase the effective length of rock cracks up to 30% compared to standard methods, which is especially important for low-permeability reservoirs.
The composition of the low-viscosity fluid and hydraulic fracturing design were specially developed for the sand reservoirs of the Kondaneft licensed areas. The necessary parameters of the synthetic polymer selected in the laboratory have been successfully field tested.
The innovative synthetic polymer fluid for geological operations is a highly effective alternative to the guar-based mixture and also has a number of significant advantages. It provides high residual proppant conductivity, quickly dissolves in cold water, which significantly reduces the time to prepare the well for work. In addition, reducing the amount of additives can increase the efficiency of hydraulic fracturing, and a simple process for controlling the quality of such a fluid reduces the time for laboratory testing before each hydraulic fracturing operation.
In the near future, this technology for intensifying oil production can be replicated to other Rosneft assets with similar geological conditions.
