Gazprom Neft, one of the largest oil producers in Russia, announced that it has finished drilling its first oil production well in the NP-8 stratum on the Novoportovskoye field, and will start developing it.
Basically, the NP-8 stratum is expected to produce approximately 25% of all the oil extracted from the Novoportovskoye oil field in the next three years. It is known as the second most significant and productive reserve that is situated within the NP-4 stratum.
According to the official website of Gazprom Neft:
“The Novoportovskoye field is one of the most significant oil and gas condensate fields in the Yamal Peninsula. It is located within the Arctic Circle, some distance from pipeline transportation infrastructure. Recoverable C1 and C2 reserves are estimated at more than 250 million tons of oil and condensate, as well as more than 320 billion cubic meters of gas inclusive of Paleozoic deposits.”
Gazprom Neft’s oil production well is being constructed by specialists from Gazpomneft-Yamal, which is also backed by experts from the company’s own science and research center. Its shaft is 4.2 kilometers long, which includes a horizontal section measuring 1.45 kilometers.
Its oil inflow is said to corroborate geologists’ initial calculations for developing the stratum. Such results were obtained by the scientists through testing exploratory wells way back in the 1970s.
All in all, 14 wells are planned to be constructed in the NP-8 stratum on the Novoportovskoye oil field by the end of 2017, reaching up to 50 by 2019.
