Variables
Description
What is this formula?
The Recovery Factor (RF) measures the fraction of an original resource that can be economically or technically recovered.
It is a key indicator in petroleum engineering, mining engineering, groundwater extraction, and geothermal resource assessment.
The value is commonly expressed as a decimal or percentage and indicates the effectiveness of extraction technologies and reservoir management practices.
When to use it
Use this formula when evaluating:
- Oil and gas reservoirs
- Mineral deposits
- Groundwater resources
- Geothermal reservoirs
- Resource development projects
Example
An oil reservoir originally contains 500 million barrels of oil in place.
Engineering studies estimate that 175 million barrels can be recovered.
Data:
Rr = 175,000,000 bbl
Ro = 500,000,000 bbl
Formula:
RF = Rr / Ro
Substitution:
RF = 175,000,000 / 500,000,000
Result:
RF = 0.35
Recovery Factor = 35%
This means that approximately 35% of the original oil can be produced using the planned recovery methods.
Applications
- Reservoir engineering
- Enhanced oil recovery
- Mining project evaluation
- Groundwater resource assessment
- Resource economics
- Production forecasting
Note
Recovery Factor is not a universal constant. Its value depends on geology, reservoir characteristics, extraction technology, economic conditions, operating constraints, and regulatory requirements. Actual recovery factors may change throughout the life of a project as new technologies or production strategies are implemented.
