1. Alekseevskoe oil field is located in Beloyarskiy administrative region of Khanty-Mansiysk Autonomous Okrug-Yugra, in 170 km to the northeast from Nyagan city. The oil field is a part of Serginskiy oil and gas district of Krasnoleninskaya oil-and-gas bearing region. The field was discovered as a result of resampling of Amninskaya area’s prospecting hole 266 drilled in 1965. In 2014 as a result of bed ЮК2 testing of prospecting hole 266, between 2360-2368 m in condition of middle dynamic head 1524 m oil flow with an oil production rate of 4.7 m³/day was received; as a result of bed ЮК10 testing between 2628-2634 m, 2635-2639 m in condition of middle dynamic head 948 m liquid-gas mixture (gas, oil and reservoir water) flow with a production rate of 8.9 m³/day was received.
2. Zapadno-Koltogorskoe oil field is located in Nizhnevartovskiy administrative region of Khanty-Mansiysk Autonomous Okrug-Yugra, in 50 km to the southeast from Raduzhnyy city. The oil field is a part of Varyeganskiy oil and gas district of Nadym-Purskaya oil-and-gas bearing region. In 2009 two prospecting holes 103 and 102 were drilled on the territory of the license block. In 2014 as a result of bed ЮВ11 and ЮВ0 testing of prospecting hole 103 commercial oil flow was received. An oil production rate of ЮВ11 was 3.4 m³/day, an oil production rate of ЮВ0 was 1.34 m³/day.
3. Ourinskoe gas and oil field is located in Kondinskiy administrative region of Khanty-Mansiysk Autonomous Okrug-Yugra, in 43 km to the west from Uray city. The gas and oil field is a part of Iusskiy oil and gas district of Priuralkay oil-and-gas bearing region. In 2013 two prospecting and appraisal wells 1 and 3 were drilled. In 2014 as a result of Vikulovskaya and Leushinskaya formations’ testing of the wells oil and gas flows were received. As a result of prospecting and appraisal well 3 testing between 856.5-863.5 m oil and water flow with a production rate of 10.1 m³/day and 3.5 m³/day was received. As a result of flow nipple testing (17.5 mm) gas flow with a production rate of 155.7 thousand m³/day was received from overlying interval between 832.8-843.3 m. As a result of A1 testing between 944-969 m (flow nipple location, 15.9 mm) gas flow with a production rate of 204.7 thousand m³/day was received, but testing between 979-988 m pure oil flow with a production rate of 2.9 m³/day was received.
4. N. Ya. Medvedev field is located in Surgutskiy administrative region of Khanty-Mansiysk Autonomous Okrug-Yugra, in 215 km to the south from Surgut city. The field is a part of Demyanskiy oil and gas district of Kaysymovskaya oil-and-gas bearing region. As a result of Ю3-4 testing of the hole 8421 between 2831-2846.4 m oil flow with a production rate of 3.8 m³/day was received.
5. Yuzhno-Trekhozernoe field is located in Kondinskiy region of Khanty-Mansiysk Autonomous Okrug-Yugra, in 4 km to the southwest from Uray city. The field is a part of Shaimskiy oil and gas district of Priuralskaya oil-and-gas bearing region. In 2013 as a result of П1 testing of the hole between 1499.5-1501.5 m oil with water flow was received (a production rate of oil was 18 m³/day, a production rate of water was 20 m³/day).
6. A.Yu. Iskrin gas-condensate field is located in the Khanty-Mansiysk administrative region of the Khanty-Mansiysk Autonomous Okrug-Yugra, in 150 km to the north from Khanty-Mansiysk sity. It is a part of Lyaminskiy oil and gas district of Frolovskaya oil-and-gas bearing region. Iskrinskoye field was named after Alexander Yur’yevich Iskrin, Deputy Chief Geologist of LLC “Exploration company Archneft”, contributed significantly to Khanty-Mansiysk Autonomous Okrug-Yugra’s oil and gas industry development. A discoverer of the field is a prospecting hole 5 of Zapadno-Unlorskaya area. As a result of ЮС8 testing between 2973 and 3005 meters, after fracturing (flow nipple location, 5 mm), gas flow with a production rate of 13.3 thousand m3 per day was received.
