A horizontal well hydraulically fractured in Urengoyskoye gas field in the northern Tyumen region of Russia confirms potential for development of the Cretaceous lower Achimov formation, Novatek reports.

A horizontal well hydraulically fractured in Urengoyskoye gas field in the northern Tyumen region of Russia confirms potential for development of the Cretaceous lower Achimov formation, Novatek reports.

Arcticgas, a joint venture of Novatek and Gazprom-Neft, completed an eight-stage frac program in the U2802 well, drilled to a total length of 5,624 m with a horizontal section of 1,500 m. Proppant volume was a record high 2,187 tons.

Arcticgas applied what Novatek described as “a unique wireless inflow monitoring technology using marketed proppant.”

It installed permanent downhole pressure and temperature gauges to provide real-time production data.

The well flowed more than 1 million cu m/day of natural gas and 500 tonnes/day of condensate.

Other Achimov zones produce gas and condensate in Urengoyskoye field. The geologically complex formation occurs below 4,000 m and has reservoir pressure exceeding 600 atm.
