specifics in Yamal
Rusneftekhim specializes in the production of gas, gas condensate and oil. In each of these areas, the company shows positive results and has great prospects.
Gas production
Rusneftekhim's operating activities are concentrated in the Yamalo - Nenets Autonomous Area in Western Siberia.
A highly productive well fund owned by the company reveals the Achimov deposits of the Urengoyskoye field in the Ach3, Ach4, and Ach5²⁻³ layers. Gas condensate deposits of these formations are prepared for industrial development and contain about 87% of the total hydrocarbon reserves.

The wells have confirmed their productivity, having been in trial operation for
approximately three years. During this period was reached a maximum value extraction
without additional production stimulation. The annual production volume amounted
to 1.1 billion m3 of natural gas and 2.6 million barrels of condensate.

A feasibility study of commissioning was prepared by «Gazprom Engineering»,
the author of «The unified development plan for hydrocarbons of the Achimov deposits
in the Urengoyskoye field».
Until the end of 2021, Rusneftekhim will complete the overhaul of the wells, wich will achieve maximum operational efficiency. The General contractor for the repair of wells is «Gazprom podzemremont Urengoy».

In the mode of commercial operation of wells, annual production will
amount to 2.069 billion m³ of gas and 5.6 million barrels of condensate.
The total production of gas condensate wells as of 2069 will amount
to 25.092 billion m³ of gas and
54.9 million barrels of condensate.

Oil production
Part of highly productive well fund owned by Rusneftekhim reveals the oil - saturated Achimov
formation Ach3 of the Urengoyskoye oil and gas condensate field. The produced crude oil is classified
as light with a sulfur content of 0.08%. The density of oil at a temperature of 20°C is 798 kg/m³.
In the mode of commercial operation annual production will amount to 400 thousand barrels.
Total production as of 2046 will be 4.4 million barrels of
oil and 0.535 billion m³ of associated gas.

Applied acidization technologies for the extraction of reserves from the
reservoirs of the Achimov formation:
Hydraulic fracturing is a method that improves the porosity, permeability and HC recovery factor from
a specific section of the reservoir adjacent to the well.
The main method of hydraulic fracturing is proppant carrier fluid injection under the pressure
higher than formation fracturing pressure. Proppant injection is carried out using specialized
pumps that are part of the hydrofrac fleet, creating a pressure exceeding 1000 atmospheres.
During the operation, the proppant wedges up the fractures created by pressure and helps to
increase the inflow through the newly created channels to the interval of the well perforation.
The most promising is the multi-stage hydraulic fracturing. To perform
multi-stage hydraulic fracturing, equipment (tie-back equipment) is lowered into
the well. Such equipment consists of several valves that are designed at different
intervals and serve for sequential hydraulic fracturing in different directions
and sections of the formation, which contributes to more efficient characteristics
of hydrocarbon production.
Sidetracking is the creation of an additional effective production channel, which allows
for the involvement of previously unused sections of the reservoir, as well as reserves
difficult to recover.
Creating a sidetrack in a vertical well is done by cutting a casing window using a reamer
and a deflecting wedge and drilling a bore. Next, the production liner is lowered for
multi-stage hydraulic fracturing. The use of sidetracking technology significantly
increases the down-spacing (i.e. reduces the need for drilling new wells and the cost
of hydrocarbon production).

Aggressive factors during production from the Achimov reservoirs
abnormal formation pressure up to 600 atmospheres
CO2 (carbon dioxide), which creates carbon dioxide corrosion of the wells equipment, as well as an elevated temperature of up to 110°C in the bottom zone, enhancing the influence of the aggressive environment on the equipment.
Solution
to prevent corrosion of equipment in the well, special alloys that are little low-susceptible to corrosive attack of aggressive environment are used, in particular, Chrome 13 alloy, which includes elements such as chromium, molybdenum, etc.
corrosion inhibitors are also used to combat aggressive environments – high-tech fluids that protect equipment from these factors.

Increasing the resource base in Yamal is part of the strategy of Rusneftekhim to expand its activities. The company plans to purchase both new licensed areas with proven hydrocarbon reserves, as well as promising little-studied areas where prospecting will be carried out.
To expand its activities and increase production potential, Rusneftekhim plans to participate in
joint ventures with Russian and foreign leaders in the oil and gas industry. The company considers
public-private partnership (PPP) to be a particularly promising form of cooperation.
