Gazprom Neft begins development of new oil stratum at its Novoportovskoye field


Gazprom Neft has completed drilling of its 1st production well within the NP-8 stratum at its Novoportovskoye field, the company reported on April 12, 2017.

 

The total length of the constructed well shaft is 4.2 kilometres, including a 1.45-kilometre 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 3 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 2nd 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.
