Mobile complex

Extraction of hard-to-recover oil reserves

The mobile complex - SCW-TRIZ, which has no world analogues, manufactured using the patented technology of supercritical water cracking (SCWC), can arrive on its own to an existing or developed oil well, deploy within a day, start supplying heat carrier to a depth not accessible to other equipment. A significant increase in the profitability of oil production.

Oil production depth: up to 7000 meters
Reservoir heating temperature: T up to 500℃
Physical pressure: P up to 40 MPa
Physical pressure at the bottom of the well: P up to 60 MPa
The increase in the Oil Recovery Coefficient: up to 65% and more
Extraction of heavy, high-viscosity, paraffin oil
Extraction of kerogens - solid, immature oil

Types of wells

SCW allows to extract oil from previously developed and depleted wells

After Hydraulic Fracturing

Hydraulic fracturing prepares a network of channels extracting 10%, and then SCWC extracts another 70-80% of oil reserves

Coiled tubing

Delivery of SCW into the well, by a system of flexible continuous pipes, without loss of temperature

Extraction up to 80%

Tests of SCW on the cores of the Bazhenov formation showed an Oil Recovery Coefficient of 80%

Equipment for the extraction of hard-to-recover oil reserves - SCW-TRIZ

The equipment has been successfully launched and has been operating in industrial mode since 2018 at the Lukoil-Komi field in Usinsk.

About 50 wells have been processed
Additional oil production from the well: 2780-3400 tons (medium)
Tests of SCW on the Bazhenov formation showed Oil Extraction - 80%

Supercritical water

The use of supercritical water (SCW) for the extraction of hard-to-recover oil reserves

Supercritical water (SCW) is chemically pure water heated under high pressure. The critical point of the beginning of the formation of SCW is 374 ℃, at a pressure of 21.8 MPa.

The optimum temperature of the heat carrier for injection into oil-bearing formations is up to 500℃, at a pressure of up to 45 MPa.

In the presence of oil sludge and asphaltene sediments in the soil, it is possible to use "closed cycle" technology - waste disposal in the SCW stream with subsequent use of the resulting decay products in the process of oil production.

The use of SCW in oil extraction:

Chemically pure water is used, without additives
The effect of heating the reservoir – 6 months or more
Modification of heavy oil into light
Reduction of sulfur content in oil
Significant increase in the profitability of oil extraction

The impact of SCW on the Environment:

Disposal of oil sludge and oiled soils
Elimination of CO2 emissions into the atmosphere
Disposal of flue gases together with heat carrier in the well
Environmentally friendly technology

Hard-to-recover oil reserves

Extraction of hard-to-recover oil reserves

More than 70% of all world oil reserves belong to hard-to-recover (HTR), the extraction of which, without the use of methods of increasing oil recovery, is economically unprofitable.

The constantly growing share of HTR in the total volume of recoverable oil reserves, and their location at depths of 1000-3000 meters, requires the use of new methods to increase the oil recovery coefficient. The most effective method of increasing the oil recovery coefficient, taking into account the depth of the main oil-bearing formations, is the technology of pumping supercritical water - SCW.

Until 2025, oil and gas companies will need at least 500 SCW-TRIZ complexes in only one oil-producing region of Russia to maintain production at the current level. The market for the use of the complex is global.

500 SCW-TRIZ complexes for the economy, this is:

3000 jobs in manufacturing and assembly
1800 jobs in the operation of complexes
300 jobs for repair and maintenance
50 specialists to adapt the technology in the fields
Export of high-tech equipment
Development of domestic technologies
The use of the industrial potential of defense enterprises in the production of civilian products
The growing prestige of Russian technologies and equipment in the world

Ecology

Closed-loop technology

Taking into account the ability of supercritical water to oxidize organic matter into simple and environmentally friendly substances - into CO2, water and thermal energy, the equipment allows, in parallel with oil production, to dispose of oil sludge and oiled soils, remove asphalt-resin-paraffin deposits, implementing closed-cycle technology.

Exclusion of flaring of associated petroleum gas

Modification of heavy oil into light, low-sulfur

Dispose of oil sludge and oiled soils
