Oil fields, discovered in 2017
1. Vostochno-Serginskoe field was discovered within the Vostochno-Serginskiy 3 subsoil plot by OJSC “Surgutneftegaz” (license KhMN 15118 NP, the validity of the license by 31.12.2017). The field is located in Surgutskiy administrative region of Khanty-Mansiysk Autonomous Okrug-Yugra, in 160 km to the north from Khanty-Mansiysk city. It is a part of Lyaminskiy oil and gas district of Frolovskaya oil-and-gas bearing region. The field was discovered as a result of exploration works. In 2015 the prospecting hole 43 was drilled. As a result of that oil content of bed ЮК2-5 was determinated. As a result of bed ЮК2-5 testing of prospecting hole 42P, between 2818-2839 m, oil flow with oil production rate of 0.21 m3/day was received in condition of hydrodynamic head of 1500.7 meters. As a result of testing ЮК4, in hole 43P, between 2821.2-2841 m oil flow with a production rate of 0.3 m3/day was received in condition of hydrodynamic head of 1503 meters.
2. Zapadno-Zimnee field was discovered by LLC “Gazpromneft-Khantos” within Zapadno-Zimniy subsoil plot (license KhMN 03069 NP). It is located in Kondinskiy region of Khanty-Mansiysk Autonomous Okrug-Yugra, in 100 km to the south from Khanty-Mansiysk city. The oil field is a part of Uvatskiy oil and gas district of Frolovskaya oil-and-gas bearing region. 1PO hole, drilled in 2017, was a discoverer. As a result of that oil-and gas content was determinated in Neocomian deposits. Beds (АС9, АС11 (Аch) and АС12 (Аch) have oil-and-gas content. Testing bed АС9, between 2247-2308 m (open hole location), oil flow with a production rate of 236 m3/day was received (depression 87 atm). As a result of testing АС11 (Аch) between 2507-2512 m and 2528-2541m oil flow with a production rate of 8.3 m³/day was received in condition of hydrodynamic head of 1185 meters. As a result of testing АС12(Аch) between 2570-2595 m oil flow with a production rate of 5.1 m3/day was received in condition of hydrodynamic head of 1764 meters.
3. Lungorskoe field was discovered by OJSC “Surgutneftegaz” within Lungorskiy subsoil plot (license KhMN 11417 NP).

The oil field is a part of Priobskiy oil and gas district of Frolovskaya oil-and-gas bearing region. The prospecting hole 4815 was drilled of the end of the year of 2016. In 2017 oil-and-gas content was determinated in the Neocomian (bed АС102) and middle Jurassic (bed ЮС2) oil-and-gas bearing complexes. As a result of bed АС92 testing, between 2916-2930 m, oil and water flow, in condition of middle dynamic head 1111 m with production oil rate of 10.78 m3/day and production water rate of 3.78 m3/day, was received. As a result of bed ЮС2 testing, between 3055.6-3080.6 m oil flow with a production rate of 1.5 m3/day was received.
4. Polesskoe field was discovered within Severo-Eguryakhskiy 2 subsoil plot by LLC “LUKOIL-West Siberia” (license KhMN 15137 NP). The field is located in Nizhnevartovskiy administrative region of Khanty-Mansiysk Autonomous Okrug-Yugra, in 83 km to the north from Nizhnevartovsk city. It is a part of Vartovskiy oil and gas district of Sredneobskaya oil-and-gas bearing region. Prospecting hole 62 Vostochno-Polesskay, drilled in 2016, was a discoverer of the oil field. Beds (БВ10, Ач1) in the Neocomian deposits have oil-and-gas content. Testing БВ10 between 2416.5-2419.5 m oil and water flow was received (a production rate of oil was 0.6 m3/day, a production rate of water was 9.6 m3/day), in condition of middle dynamic head 1405 m. Testing Ач1 between 2558-2563 m, after fracturing, oil and water flow was received (a production rate of oil was 9.26 m3/day, a production rate of water was 25.94 m3/day).
5. Yuzhno-Indrinskoe oil-and-gas field was discovered within Karabashskiy 2 subsoil plot by JSC “Evrotek Yugra” (license KhMN 03240 NP). The field is located in Kondinskiy administrative region of Khanty-Mansiysk Autonomous Okrug-Yugra, in 47 km to the southeast from Uray city. It is a part of Uisskiy oil and gas district of Priuralkaya oil-and-gas bearing region. The field was discovered as a result of exploration hole 4 drilled in 2014.
As a result of ВК1 (Vikulovskaya formation) testing between 837 and 849 meters (flow nipple location, 11.1 mm), oil and water flow with a production oil rate of 0.4 m3/day was received. As a result of А1 (Leushinskaya formation) testing between 962 and 975.5 meters (flow nipple location, 12.7 mm), gas flow with a production rate of 120.6 thousand m3/day was received, between 979 and 989.5 meters oil and water flow with a production oil rate of 2 m3/day.
