Gazprom Neft has completed drilling of the first bilateral production well (with horizontal shafts of 1,000 metres) on the Yamal Peninsula. The project is being undertaken at the Novoportovksoye oil and gas condensate field, development of which is being managed by Gazpromneft Yamal, a subsidiary of Gazprom Neft.

A multilateral well allows to increase the catchment area of a reservoir; one of the well boreholes is, accordingly, located on the periphery of a deposit in order to bring into development reserves some distance from the vertical borehole of the well. Economic viability is thus improved, through more intense production of hydrocarbons, as well as through lower infrastructure development costs. The Novoportovskoye well runs to a total length of 4,600 metres, with the horizontal sections set at a depth below 2,000 metres. The company plans to use one of the horizontal sections for multistage fracking of the reservoir. Round-the-clock drilling of the Novoportovskoye well was supported by specialists from the Gazprom Neft Scientific and Research Centre.

Vadim Yakovlev, First Deputy CEO, Gazprom Neft, commented: 'This marks the first ever bilateral well to be drilled under Arctic conditions. The experienced gained will allow us to start building wells of more complex construction at the Novoportovskoye field, including increasing the length of horizontal sections to 2,000 metres. Greater well production capacity will, in turn, increase the economic viability of developing this field.'
