The importance of oil and gas for the Russian Federation is difficult to overestimate. These are raw materials for the production of fuels and lubricants, and for the chemical industry, and fuel. The presence of a large number of oil and gas condensate fields allows the country not only to provide the domestic market with the necessary products from oil and gas, but also to export it to other countries of the world.
Deposits of the Krasnoyarsk Territory
Oil and gas production in the region is of strategic importance in its economic and social development. The Krasnoyarsk Territory is located in Eastern and Central Siberia and has rich mineral deposits. In particular, it has 25 oil and gas fields. This is about 25% in the structure of the industrial complex of the region. The largest are the Vankorskoye, Ichemminskoye, Tagulskoye and Yurubcheno-Tokhomskoye deposits. According to Rosneft, this is one of the very promising areas that should be developed in the near future. This is not only the emergence of new oil and gas pipelines and economic profits. It is also the development of the regions of the Krasnodar Territory, which until now have not been settled and developed.
Some information about the field
According to the geostructural feature, the Yurubcheno-Tokhomskoye field (Krasnoyarsk Territory) belongs to the Baikit anteclise in the west of the Siberian platform (anteclise is the raising of the earth's surface over a vast flat area that develops over several geological periods). In turn, the Baikit anteclise belongs to the Lena-Tunguska oil and gas province.
According to experts, the Yurubcheno-Tokhomskoye oil and gas condensate field has about 321 million tons of oil in the C1 + C2 category and 387 billion cubic meters of gas in the C1 + C2 category. Natural resources are located at a depth of about 2.5 kilometers. The saturation of the reservoirs with oil and gas is uneven. In the south, the intervals do not exceed a thickness of 72 meters, and in the north they reach 172 meters.
Resource Description
The formation of minerals lasted several geological periods. The Yurubcheno-Tokhomskoye field has a complex structure. The distribution of oil and gas strata is limited by clay deposits and outcrops of crystalline rocks. The layers are shielded by clay-carbonate rocks. Oil-water contact was found at depths of 2.07 kilometers, and gas-oil contact - 2.02 kilometers.
However, the amount of raw materials is so large even in confirmed areas that it makes sense to develop, even if unconfirmed formations are poor in resources and will not make the necessary profitability of their production.
Field Development Project
Oil and gas were discovered back in the 1980s, but the decision to produce it was made only a few years ago. In 2007, the Tomsk Scientific Research and Design Institute of Oil and Gas completed a technological project. According to him, the Yurubcheno-Tokhomskoye field will be developed in three stages.
At the first stage, exploratory and industrial wells should be completed, complexly constructed fractured reservoirs should be created, a gas compressor station, oil reception and delivery points, facilities for the preparation of raw materials, etc.
The second and third stage is the continuation of production development, which allows to increase production capacities and launch the petrochemical complex of the Krasnoyarsk Territory in 2020.
Stages of development of natural oil reserves in the Krasnoyarsk Territory
The second value in oil production is the Yurubcheno-Tokhomskoye field. Rosneft transferred the authority to develop it to its subsidiary OAO East Siberian Oil and Gas Company. The first development phase is planned for 2014-2019. During this period of time, 170 wells with horizontal endings should be drilled. The priority site should be launched in 2017. By 2019, it is planned to receive 5, 000, 000 tons of oil per year. The use of associated gas is also expected - by re-injection into the reservoirs and for technological needs.
Due to the fact that a project was developed and approved back in 2007, work began on the construction of the Kuyumba-Tayshet oil trunk pipeline in 2013. This pipeline should connect the Yurubcheno-Tokhomskoye field with the East Siberia-Pacific Ocean trunk line. It is through this pipeline that oil will be pumped to places of further use and redistribution.
