Rospan International, Rosneft subsidiary, conducted record hydraulic fracturing (HF) operation on the East Urengoi license area with the use of HiWay (TM) highly conductive fractures technology that has become record fracing operation on the gas-condensate field. 300 tons of proppant have been pumped one-time within 5 hours that is equivalent to 550 tons of a proppant pumped by conventional technology. During well development production rate reached more than 1 million m3 / day of gas and 300 tons / day of gas condensate.

Fracturing technology with the creation of HiWay highly conductive fracture (TM) refers to the cluster HF types. The technology is applied as a pilot one, as one of the possible technical solutions for the implementation of Rospan International strategy to increase productivity of new wells, decommissioning with geology degradation in the peripheral areas of the Achimov formations of the East- and the Novo Urengoy license areas.

Rospan experts conducted six pilot operations with the use of this technology. Compared with conventional HF technology with the equivalent injection volume, wells productivity was increased by 15-20%.

In the short term Rospan plans to increase proppant injection amount in some wells, providing maximum efficiency of well completion. In order to specify operations parameters specialists are investigating productivity dynamics of  the wells, where advanced hydraulic fracturing technology has been used .Along with this the ways are worked out to overcome the existing technology limitations for conducting operations with the planned increased injection capacity.

Rospan International operates two licences in the Urengoi area in the Yamal-Nenets Autonomous Okrug: East Urengoiskoye and Novo-Urengoiskoye. These cover deep layers of the super-giant Urengoiskoye field. Rospan International is a 100% RN Holding (Rosneft) subsidiary.
