PROBLEMS OF THERMODYNAMIC, GAS CHEMICAL AND POWER PROCESSES OF OIL & GAS PRODUCTIONS
OBJECTIVE:
development of scientific and methodological bases for the projecting and creation of energy and gas chemical complexes to reduce the carbon trace of Arctic objects of the mineral resource complex of the Russian Federation.
ACTUALITY:
Energy is the basement of the economy and the main driver of its development. In this regard, ensuring universal access to cheap, reliable, safe and environmentally friendly energy sources is one of the priorities in the context of global stable development.
Energy is the foundation of the economy and the main driver of its development.
The concept of developing a remote Arctic oil and gas field with the possibility of producing and transporting blue hydrogen associated with methanol, ammonia and cyclohexane
This is directly indicated in the framework of the seventh UN objective and is indirectly traced in other sustainable development objectives, the achievement of which depends on the efficiency of the use (rational production and consumption) of natural resources, including raw materials.
The technologies developed within the framework of the scientific direction "Green Energy-underground space" are aimed at the rational use of natural resources and the reduction of the "carbon traces" from the production, transportation and use of oil and gas in order to ensure the stable development of the energy industry of the Russian Federation.
The concept of developing a remote Arctic gas field with the possibility of extracting and transporting solid carbon and turquoise hydrogen in the form of hydride using a dry cargo ship
1. The program of additional professional education "Complex utilization of associated petroleum gas in field conditions" has been developed and is being implemented.

2. The concept of "Gas-To-Chem" has been developed, which presents methods for increasing production efficiency through mutually complementary gas-chemical processes that provide flexibility in the supply of hydrogen and its derivatives by diversifying production.

3. An energy-efficient and eco-friendly technology for the utilization of associated petroleum gas has been developed. It is used in the conditions of oil fields, the degree of associated petroleum gas utilization at which can be brought to 100%. The technology combines a GTC (Gas-to-Chemical) process, a binary cycle, and CO2 capture.

4. A technological scheme for the production of "blue" hydrogen y non-catalytic autothermal reforming, followed by a catalytic reaction of water vapor, as well as the capture and liquefaction of carbon dioxide for its disposal, has been developed.

DEVELOPMENT AND DRILLING OF WELLS IN THE ARCTIC
OBJECTIVE:
multi-fold cost reduction due to the replacement of sand-filled areas and sites with modular stilt bases that are installed in winter and provide year-round steady-state tubeless drilling of deep exploration and production wells in the areas of unstable frozen soils and swamps with the risk of seasonal flooding.
ACTUALITY:
The development of reserves in the northern outlying territories, including the Arctic ones, is associated with a number of problems when drilling exploration and production wells.
The traditional technology of drilling equipment deployment implies a significant amount of preliminary work to fill the site, taking into account possible natural complications. The cost of such work increases due to non-compliance with the constructional norms of the fine-grained powdery sand used in the territories of the development objects.
The development of reserves in the northern outlying territories, including the Arctic ones, is associated with a number of problems when drilling exploration and production wells.
One of these problems is the construction of wells in the territories in the zone of permafrost distribution, which are subject to seasonal flooding.
Absence of an alternative to sand filling of the site leads to a significant increase in financial costs, which increase the total cost of construction of exploration wells. In addition, sand filling has both technological and environmental disadvantages, which cause a reduction in the service life of the fillable areas.
Modular base for drilling an exploration well from a drilling equipment
Modular base for operational drilling of wells from a drilling equipment
Based on the research and design studies carried out at the Mining University, it was determined that the cost of constructing modular stilt foundations is on average 50% less than the cost of organizing and maintaining sand deposits.

To verify the modeling results, it is planned to carry out full-scale tests of the load-bearing capacity of a single stilt foundation module with a load distributed on it in the conditions of seasonally flooded frozen soils in the coastal area of the Kara Sea. At the same moment, remote year-round monitoring of changes in the stress-strain state of modular stilt foundations is provided.

OIL AND GAS DEVELOPMENT FACILITIES MANAGEMENT
OBJECTIVE:
development of devices for preventing hydrate formation that do not require energy supply from external sources and have enough trustworthiness.
ACTUALITY:
A general problem of gas production and its transportation through pipelines is hydrate formation. Hydrates are formed under certain thermobaric conditions, depending on the composition of the gas, and can prevent the functioning of wells and pipelines.
The problem of gas production and its transportation through pipelines is hydrate formation.
INJECTION OF METHANOL INTO THE WELL
Most often, hydrates are formed due to an extreme decrease in the temperature of the gas flow.
Dosing blocks are used to ensure the dosing of the supply of methanol to the downhole flow. Methyl is a strong cumulative poison, the delivery and use of which sometimes leads to a multiple increase in costs.
The requirement of the fields for methanol is estimated at 5-15 thousand tons per year (12 thousand tons per year for the Chayandinsky

Oil- and- gas condensate reservoir, which at a price of 43 thousand rubles per ton is about 500 million rubles per year).

GAS HEATING BEFORE REDUCTION AT THE GAS DISTRIBUTION STATION
Flow-through torch heaters are used, which use a part of the transported gas to generate heat.
The amount of gas for own needs is about 0.3 to 0.5% of the total pumping (for gas distribution station) of St. Petersburg and the Leningrad Region, this is 40.7 million m3 per year, or, at a price of 3470 rubles per thousand m3, 140 million rubles per year).
