Gazprom Neft begins development of oil stratum at Novoportovskoye field

MOSCOW -- Gazprom Neft has completed drilling of its first production well within the NP-8 stratum at its Novoportovskoye field. The total length of the constructed well shaft is 4.2 km, including a 1.45-km horizontal section. The oil inflow obtained confirms geologists’ forecasts on prospects for developing this stratum.

The NP-8 stratum, currently being brought into commercial production, is expected to deliver approximately 25% of all oil produced at the Novoportovskoye field over the next three years, and more than 10% of all oil produced at Novy Port over the course of its productive life. The NP-8 stratum is the second most productive, the most significant reserves being contained within the NP-4 stratum, currently under development.

Well construction was undertaken by specialists from Gazpomneft-Yamal, supported by experts from the Gazprom Neft Science and Research Centre. A total 14 wells are expected to be drilled at the Novoportovskoye field’s NP-8 stratum by the end of 2017, reaching 50 wells by 2019.

The Novportovskoye formation includes several strata, the most productive of which is the NP-4 stratum. These strata comprise marine and coastal sandstones, alternating with silts and clays. Commercial oil inflows from the NP-4 stratum were obtained as a result of testing via exploratory wells in the 1970s.
