The Reservoir Flow Rate Calculator is a powerful tool used in the field of reservoir engineering to determine the flow rate of fluids through underground rock formations. It plays a crucial role in the oil and gas industry, aiding in the optimization of reservoir production.
Formula of Reservoir Flow Rate Calculator
The calculator employs the following formula:
Q = (k * A * (P1 - P2)) / (μ * L)
Where:
- Q is the flow rate (measured in cubic feet per day).
- k represents the permeability of the reservoir rock (measured in millidarcies).
- A denotes the cross-sectional area of the reservoir (measured in square feet).
- P1 and P2 signify the pressure difference across the reservoir (measured in pounds per square inch or psi).
- μ stands for the viscosity of the fluid (measured in centipoise).
- L represents the length of the reservoir (measured in feet).
General Terms Table
To facilitate ease of use, here is a table of commonly searched terms:
| Term | Description |
|---|---|
| Permeability (k) | Measure of rock’s ability to transmit fluids |
| Cross-Sectional Area (A) | Surface area of the reservoir |
| Pressure Difference (P1 – P2) | Variation in pressure across the reservoir |
| Fluid Viscosity (μ) | Thickness or stickiness of the fluid |
| Reservoir Length (L) | Extent of the underground rock formation |
Example of Reservoir Flow Rate Calculator
Let’s illustrate the usage of the Reservoir Flow Rate Calculator with a practical example:
Assume:
- Permeability (k) = 100 md
- Cross-sectional Area (A) = 500 ft²
- Pressure Difference (P1 – P2) = 100 psi
- Fluid Viscosity (μ) = 2 cP
- Reservoir Length (L) = 1000 ft
Plugging in these values into the formula, we get:
Q = (100 * 500 * (100 - 0)) / (2 * 1000) = 2500 ft³/day
