Minerals of the Nenets Autonomous Okrug

1. Hydrocarbon potential

The Nenets Autonomous Okrug is strategically important in the fuel and energy complex of the European North of Russia.

The hydrocarbon potential of the Nenets Autonomous Okrug is located in the northern part of the Timan-Pechora oil and gas basin. Of the over 230 oil and gas deposits of Timan-Pechora, 91 are located in the Nenets Autonomous Okrug. Total recoverable oil reserves are estimated at more than 1 billion tons; gas - more than 500 million cubic meters; condensate - more than 20 million tons.

Today, the distributed subsoil fund contains more than 95% of proven oil reserves and more than 50% of free gas.

As a result of geological exploration, new promising areas of geological exploration were identified within the northern part of the Izhma-Pechora Depression and the Malozemelsky-Kolguyev monocline; recommendations are given on involving promising objects in the development; The groundwork for licensing for a 3-year period has been prepared. Based on the results of completed regional seismic surveys and a comprehensive interpretation of geological and geophysical data, a group of promising objects in the northern part of the Izhma-Pechora Depression has been identified; An assessment of oil resources was carried out, 12 promising areas with initial recoverable oil resources of more than 240 million tons were allocated and proposed in the licensing program.

2. The state of the mineral resource base

At present, deposits and manifestations of coal, manganese, radioactive elements, impact diamonds, barite, fluorite, stone raw materials and other types of minerals have been established on the Ugra Peninsula, for the assessment of which exploration and exploration work is necessary. In modern conditions, the most real objects of industrial development may be deposits and manifestations of coal, manganese, barite and fluorite.

Along with the Ugra Peninsula (Pai-Khoi), the Vaigach and Novaya Zemlya Islands, the second promising region for identifying deposits of ore and non-metallic minerals is North Timan, which has not been sufficiently studied, but now has significant reserves and resources of gemstone raw materials (Timan agates). Requires an in-depth assessment of the probable potential of diamond bearing and gold bearing (by analogy with Middle Timan in the territory of the Komi Republic).

2.1 Coal

The Pechora coal basin covers an area of ​​about 90 thousand square kilometers and is located on the territory of the Komi Republic and the Nenets Autonomous District of the Arkhangelsk Region. A significant part of it is located beyond the Polar Urals.

In 2003, V.P. Kuklev (Komigeolfond) reassessed the coal resource base in the Pechora basin, including the territory of the Nenets Autonomous Okrug.

The total geological resources of coal in the Komi Republic amounted to 128.071 million tons, in the Nenets Autonomous Okrug - 139.679 million tons. Of the total geological resources of the coal in the basin, 52% is located on the territory of the Nenets Autonomous Okrug, of which 122 billion tons are estimated as conditional.

Explored reserves are almost all located in the Komi Republic (97%).


2.2 Non-Metallic Minerals

Barite

The planned prospects for increasing oil and gas production in areas adjacent to the north of the Urals provide for the ever-growing demand for drilling barite concentrate. The resources of the Khoylinskoye field currently being developed as applied to the new more northern areas of hydrocarbon resources development can be supplemented by the Paykhoy baritone province, where the Ems and Serpukhov stratigraphic levels of baritic accumulation are established.

Fluorspar (fluorite).

In the northeast of the European part of the country, in the Nenets Autonomous Area, a large and very promising Ural-Novaya Zemlya Late Hercynian fluorite province has been established, covering the area of ​​development of the Pre-Paleozoic and Paleozoic sediments. The South Paykhoy and Amderma fluorite-bearing zones stand out.

The South Paykhoy fluoriferous zone is elongated by a narrow strip along the southwestern wing of the Paykhoy anticlinorium for almost 250 km. It combines a number of fluorite manifestations in carbonate and siliceous-carbonate deposits, mainly of the Visean age. Among them, the most promising is the Buredan ore occurrence with monomineral fluorite and lead-zinc-fluorite ores.

The Boredan ore occurrence is located in the southeastern part of Pai-Khoya (the territory of the Nenets Autonomous Area), in the river basin. Silova Yah. The area is not economically developed

The manifestation is polymetallic fluorite. The main mineral is fluorite, and the accompanying ones are galena and sphalerite.

P1 forecast resources were estimated at the ore occurrence, which amount to 144950 tons. In the course of more detailed work, it is possible to identify additional ore bodies, and new ore occurrences within Pai - Khoya.

The Amderma fluorite-bearing zone is located at the northwestern end of Pai-Khoya and can be traced 25 km from the northwest to the southeast. It includes the Amderma fluorite deposit itself and numerous manifestations of the southern flank, isolated in several ridge highlands.

Thus, the South Paykhoy and Amderma fluoriferous zones possess high quality fluorite resources and reserves, which, after their industrial assessment, can become the raw material base of many industries of the Urals and the European part of Russia.

Surface and groundwater

The hydrographic network within the Nenets Autonomous Okrug is very dense, mainly due to small rivers and countless small lakes. About 2,000 watercourses of various lengths flow within the okrug, there are more than 1,500 lakes. The territory is characterized by significant wetland.

The main source of nutrition for watercourses is meltwater, and groundwater in the winter. Over half of the annual runoff is discharged by streams in the spring during the flood period. A major role in nutrition belongs to precipitation. The water supply regulator of the watercourses is the waters of numerous swamps, as well as groundwater.

The peculiarities of the region, which determine a rather difficult situation with the supply of high-quality drinking water to the population, include factors of climatic and geographical location: wide

distribution of perennial frozen rocks, significant swampiness of the territory, the influence of the sea in coastal areas.

1854 rivers with a total length of 47144 km flow in the district. The largest are:

- Pechora - 1809 km long, catchment area - 322 thousand km2;

- Chernaya - 308 km, catchment area - 7290 km2;

- Shapkina - 499 km, catchment area - 6570 km2;

- Sula - 353 km, catchment area - 10,400 km2;

- Oma - 268 km, catchment area - 5050 km2.

All these rivers have especially valuable fishery value. The features of surface water bodies are a high content of iron compounds and organic substances, which makes it possible to use most of them as drinking water only after preliminary preparation.
