Gazprom Neft has finished drilling the first bilateral production well—with horizontal shafts of 1,000 m—on the Yamal Peninsula.
The project is being undertaken at Novoportovksoye oil and gas condensate field, development of which is being managed by Gazpromneft Yamal, a subsidiary of Gazprom Neft.
The Novoportovskoye well runs to a total length of 4,600 m, with the horizontal sections set at a depth below 2,000 m. The company plans to use one of the horizontal sections for multistage fracing of the reservoir. Round-the-clock drilling of the Novoportovskoye well was supported by specialists from the Gazprom Neft Scientific and Research Centre.
“This marks the first ever bilateral well to be drilled under Arctic conditions,” Vadim Yakovlev, First Deputy CEO, Gazprom Neft, said. “The experienced gained will allow us to start building wells of more complex construction at Novoportovskoye field, including increasing the length of horizontal sections to 2,000 m. Greater well production capacity will, in turn, increase the economic viability of developing this field.”
