Oil fields, discovered in 2020
Four oil fields were discovered in 2020 totally, recoverable oil reserves are 1.4 million tons of category С1, 2.5 million tons of category С2.
1. Vostochno-Olkhovskoe oil field was discovered within the Vostochno-Olkhovskiy subsoil plot (license KhMN 03321 NP) by company “YugraNefteRazvedka”. The field is located in Beloyarskiy administrative region of Khanty-Mansiysk Autonomous Okrug-Yugra, in 174 km to the northeast from Nyagan city. It is a part of Serginskiy oil and gas district of Krasnoleninskaya oil-and-gas bearing region. The plugged and abandoned hole Vostochno-Olkhovskaya 310 drilled in 2002 was retested in 2020. As a result of that oil-and-gas content of Tyumen suite (bed Ю2), middle Jurassic oil-and-gas bearing complex was determined.
As a result of bed Ю2 testing between 2745-2764 meters, an oil flow with an oil production rate of 2.16 m3/day in condition of depression 17.85 atm was received.
2. Severo-Zapadno-Pylinskoe oil field was discovered within the Zapadno-Pylinskiy subsoil plot (license KhMN 02873 NP) by company «Pylinskoe». The field is located in Nizhnevartovskiy administrative region of Khanty-Mansiysk Autonomous Okrug-Yugra, in 34 km to the northeast from Nizhnevartovsk city. It is a part of Vartovskiy oil and gas district of Sredneobskaya oil-and-gas bearing region. Two slant prospecting and exploration 1P and 2P wells penetrated deposits of Tyumen and Vasyugan suites were drilled on Yuzno-Tarhovskoe elevation in 2019. As a result of that oil-and-gas content of Vasyugan suite (bed ЮВ11). As a result of bed ЮВ11 testing between absolute depth mark 2501.6-2505.8 meters the oil and service water flow with an oil production rate of 18.7 m3/day and the oil flow with a production rate of 14.1 m3/day were received. As a result of 2P well testing between absolute depth mark 2503.7-2511.7 meters the oil and service water flow with a production rate of 16.5 m3/day, the oil flow with a production rate of 16.5 m3/day were received.
3. Novo-Salymskoe oil field was discovered within the Salymskiy-2 subsoil plot (license KhMN 03667 NP) by company “Salymskiy-2”. The field is located in Nefteyuganskiy administrative region of Khanty-Mansiysk Autonomous Okrug-Yugra, in 111 km to the southeast from Khanty-Mansiysk city It is a part of Salymskiy oil and gas district of Frolovskaya oil-and-gas bearing region. In 2019 the prospecting hole № 3PO was drilled. As a result of that oil-and-gas content was determined in middle Jurassic (bed ЮС2-3 and Ю4-5). As a result of bed ЮС2-3 testing between 3010-3024 meters, a fluid flow with a production rate of 1.51 m3/day was received (an oil production rate was 0.85 m3/day). As a result of bed Ю4-5 testing between 3044-3063 meters, an oil flow with a production rate of 1.94 m3/day in condition of depression 210.2 atm was received.
4. Solkhem oil field was discovered within the Salymskiy-3 subsoil plot (license KhMN 03659 NP) by company “Gazpromneft-Salym”. The field is located in Khanty-Mansiyskiy administrative region of Khanty-Mansiysk Autonomous Okrug-Yugra, in 119 km to the southeast from Khanty-Mansiysk city It is a part of Uvatskiy oil and gas district of Frolovskaya oil-and-gas bearing region. In 2019-2020 two prospecting holes № 5PO and №5PO-GS were drilled. As a result of that oil-and-gas content was determined in Bazhenov deposits (bed ЮС0). As a result of bed ЮC0 testing, after fracturing, a fluid flow with a production rate of 41 m3/day was received (an oil production rate was 28 m3/day).
