LUKOIL-Western Siberia, a wholly owned LUKOIL subsidiary, has tested upgraded well completion assemblies for multi-stage hydrofracturing at Yugra fields.

Apart from a liner hanger and hydrofracturing equipment, the new assembly incorporates swelling packers with hybrid elastomers. Compared with conventional methods, the upgraded technology, tested at five wells of Imilorskoye and Tevlinsko-Russkinskoye fields under the technical supervision by TAM International, gives higher flow rates.

The hybrid elastomers guarantee a total isolation of the hydrofractured areas, ensure a much better timing of the assembly's trip down the well and secure from all possible technological risks due to their ability to swell in any well fluid.

LUKOIL is one of the major international oil and gas companies that accounts for more than 2% of the world's oil production and around 1% of the proven hydrocarbon reserves. While having the full production cycle, the Company exercises full control over the whole production chain – from oil and gas production to petroleum product sales. The Russian Federation accounts for 88% of hydrocarbon reserves and 83% of hydrocarbon production, with the main activities concentrated in four (4) federal districts, including the Northwestern, Volga, Urals and Southern Federal Districts.
