Exploration works information over 2016:

 

From January, 31 to February, 3, 2017 Khanty-Mansiysk Autonomous Okrug – Yugra’s exploration works results for 2016 and plans for 2017 were reviewed by the Department for Geology and Subsoil Licensing of the Subsurface Resources Management Department on the Ural Federal District (URALNEDRA) along with Autonomous Institution “V.I. Shpilman Research and Analytical Centre for the Rational Use of the Subsoil”.

The planned volumes of 2016 exploration works were implemented mostly by the major oil companies OJSC “Surgutneftegaz”, PJSC “LUKOIL”, PJSC “Rosneft”, PJSC “Russneft”, PJSC “Gazprom”. Five fields had been discovered (Leklorskoe field, Taurovskoe field, Zapadno-Ikilorskoe field, Yukkun-Eganskoe field, Vostochno-Nazymskoe field).

The volume of 2016 exploration works was 297 thousand meters, including preliminary drilling – 105.9 thousand meters, 2 D seismic prospecting – 4232 line kilometers, 3 D seismic prospecting – 3841 km2. Incremental commercial reserves B1C1 (identified and estimated categories) was 262.6 million tons, including due to exploration drilling – 75.8 million tons. Oil production figures for 2016 indicated 239.15 million tons in the Okrug. 70 per cent of incremental reserves have been achieved by exploration drilling, production of developed reserves have been compensated by 28.9 per cent.

1. Leklorskoe field was discovered within the Surgutskiy subsoil plot by OJSC “Surgutneftegaz” (license KhMN 12170 NP). The field is located in Surgutskiy administrative region of Khanty-Mansiysk Autonomous Okrug-Yugra, in 195 km to the north from Surgut city. It is a part of Surgutskiy oil and gas district of Sredneobskaya oil-and-gas bearing region. The field was discovered as a result of exploration works. In 2005 the prospecting hole 6204 was drilled as a result of that oil-and gas content was determinated in shelf deposits of the complicated sub-complex of the Neocomian oil-and-gas bearing complex, bed БC92 of Ust-Balykskaya formation. In 2006 oil-and-gas content was determinated in Achimov part of the Neocomian oil-and-gas bearing complex, bed Ach3 and the Vasyuganskiy oil-and-gas bearing complex, bed ЮС1. As a result of bed БC92 testing of prospecting hole 6204P, between 2739-2746 m oil flow with an oil production rate of 0.61 m3/day was received; as a result of bed Ach3 testing of prospecting hole 6204P between 2851.5-2865 m, after fracturing, in condition of middle dynamic head 873.5 m oil flow with a production rate of 7.34 m3/day was received. As a result of testing ЮС1, in hole 6206P between 2982.5-2991.6 m oil flow with a production rate of 2.7 m3/day was received.

2. Taurovskoe field was discovered within the Taurovskiy subsoil plot by LLC “Evro-Soyuz KhMAO” (license KhMN 14779 NP). The field is located in Surgutskiy administrative region of Khanty-Mansiysk Autonomous Okrug-Yugra, in 180 km to the south from Surgut city. It is a part of Yuganskiy oil and gas district of Kaysymovskaya oil-and-gas bearing region. Oil-and-gas content is connected with deposits of middle Jurassic deposits of Tyumen suite. Bed Ю2 and bed Ю31 have oil-and-gas content. Testing hole 503, in bed Ю2, between 2922-2932 m oil flow with a production rate of 2.4 m3/day was received (depression 220 atm). Testing hole 501/1, in bed Ю31, between 2921-2926.5 m oil flow with a production rate of 1.63 m3/day was received.

3. Zapadno-Ikilorskoe field was discovered within the Ikilorskiy subsoil plot by LLC “LUKOIL-West Siberia” (license KhMN 15122 NP). The field is located in Surgutskiy administrative region of Khanty-Mansiysk Autonomous Okrug-Yugra, in 85 km to the north from Surgut city. It is a part of Surgutskiy oil and gas district of Sredneobskaya oil-and-gas bearing region. In 2016 prospecting hole 312 was drilled within Nizhne-Ikilorskaya structure. As a result of that oil-and-gas content of Vasyuganskiy (bed ЮC11) and middle Jurassic (bed ЮС21) oil-and-gas bearing complexes. Testing ЮC11 between 2879-2882 m oil and water flow was received (a production rate of oil was 43.1 m3/day, a production rate of water was 2.3 m³/day), in condition of depression 6.3 MPa. After fracturing of bed ЮС21, between 2950-2954 m oil and water flow was received (a production rate of oil was 8.8 m3/day, a production rate of water was 4.2 m3/day).

4. Vostochno-Nazymskoe field was discovered within Lyaminskiy 2 subsoil plot by OJSC “Surgutneftegaz” (license KhMN 13493 NP). The field is located in Khanty-Mansiyskiy administrative region of Khanty-Mansiysk Autonomous Okrug-Yugra, in 187 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. Testing hole 961P, in bed ЮК2-5, between 2735-2757 m, in condition of middle dynamic head 742 m, oil flow with a production rate of 3.27 m3/day was received.

5. Yuddun-Eganskoe field was discovered within Severo-Eguryakhskiy subsoil plot by LLC “LUKOIL-West Siberia” (license KhMN 15123 NP). The field is located in Nizhnevartovskiy administrative region of Khanty-Mansiysk Autonomous Okrug-Yugra, in 92 km to the northwest from Nizhnevartovsk city. It is a part of Vartovskiy oil and gas district of Sredneobskaya oil-and-gas bearing region. Prospecting hole 93 drilled in 2016 was a discoverer of the oil field. Testing it flow oil with water was received from bed БВ10, bed Ach1, bed Ach3, bed ЮВ11. Testing БВ10 between 2509-2513.5 m oil and water flow was received (a production rate of oil was 9.5 m3/day, a production rate of water was 43.3 m3/day), in condition of depression 11.4 MPa. After fracturing of bed Ach1, between 2656-2660 m oil and water flow was received (a production rate of oil was 8.1 m3/day, a production rate of water was 14.4 m3/day). After fracturing of bed Ach3, between 2748-2752 m oil and water flow was received (a production rate of oil was 0.7 m3/day, a production rate of water was 7 m3/day) in condition of depression 12.1 MPa. Testing ЮВ11 between 2818.4-2824 m oil and water flow was received (a production rate of oil was 37.9 m3/day, a production rate of water was 20.22 m3/day), in condition of depression 12.5 MPa.
