Enhanced oil recovery
Enhanced oil recovery
- is a set of measures aimed at increasing the amount of oil production from oil reservoirs by optimizing processes within the reservoir or changing its physical and chemical properties. This service includes the use of various technologies and methods, the purpose of which is to increase the efficiency of oil production from wells.
The main methods of enhanced oil recovery include:
- Introduction of chemical reagents: The use of special chemical reagents to improve formation permeability, reduce the viscosity of the oil fluid, reduce water content and increase well production.
- Use of hydraulic fracturing technologies: The use of high pressure to create fractures in the rock, which increases permeability and improves the flow of oil to the well.
- Thermal stimulation: The use of formation heating technologies, such as thermal spalling or steam injection, to increase the mobility of oil and improve its performance displacement from the pore space.
- Application of hydraulic fractionation methods: Use of hydraulic fraction to create cracks in the rock and improve permeability, which helps to increase oil production.
- Operation of secondary and tertiary recovery methods: Introduction of technologies secondary and tertiary stimulation of the reservoir (for example, dewatering and polymer injection) to increase oil yield from the reservoir.
