Khanty-Mansiysk, March 31 - Neftegaz.RU.
Gazprom Neft subsidiary Gazpromneft-Khantos has acquired development rights to deep strata at the southern section of the Priobskoye field in the Khanty-Mansi
Autonomous Okrug, increasing reserves by more than 10.4 million tonnes of oil.
Gazpromneft-Khantos was awarded rights to hydrocarbon exploration and production in deep horizons at the southern section of the Priobskoye field, with the Federal Subsoil Resources Management Agency (Rosnedra) making appropriate adjustments to the terms of the original license, allowing the company to begin developing deposits forming part of the Priobskoye field but previously designated open acreage.
Gazpromneft-Khantos had, hitherto, been developing strata lying at a depth of 2,700 m. Increasing this limit to 3,200 m gives the business access to Tyumenskaya and Achimovsky strata, as well as to the Bazhenov
Formation. According to the State Reserves Register, this will open up subsoil usage rights to reserves in place of more than 10.4 million tonnes of oil and approximately 2.5 million tonnes of recoverable reserves.
The results of investigations into Achimovsky strata in the southern part of the Priobskoye field were a prerequisite for extending the license - the business having obtained oil-saturated inflow of 51 tonnes per day following the drilling of a 3,300-m prospecting well in 2019, confirming the commercial viability of developing the block’s Achimovsky
Gazpromneft-Khantos plans to drill more than 30 horizontal wells, involving multi-stage fracking, at a pre-tested block from 2020. Peak production is expected to be reached in 2023, reaching more than 400,000 tonnes of oil equivalent per year.
“Bringing hard-to-recover reserves into development is a key strategic area in Gazprom Neft’s expansion of its resource base. The company has built up extensive and successful experience in hydrocarbon production at Achimovsky strata in the Khanty-Mansi and Yamalo-Nenets Autonomous Okrugs. These skills, together with existing production infrastructure, will prove an advantage for us in developing lower formations in the southern part of the Priobskoye field. Oil & gas reserves in place at Achimovsky strata throughout W.Siberia stand at approximately 35 bln tonnes. Increasing access to these colossal reserves means we can not only maintain current production levels at existing fields, but also create the opportunity to increase these.”, said Yuri Masalkin Director for Geological Exploration and Resource Base Development, Gazprom Neft.
