The Free Water Excess Calculator helps you determine the amount of free water available in a reservoir by subtracting the connate water volume from the total water volume.
Key Concepts
- Total Water Volume: The entire amount of water present in the reservoir.
- Connate Water Volume: The water that is naturally trapped in the reservoir rock, usually non-movable and not recoverable.
Calculation Formula
\[ \text{Free Water Excess} = \text{Total Water Volume} - \text{Connate Water Volume} \]
Example Calculation
If the total water volume is 500 m³ and the connate water volume is 100 m³: \[ \text{Free Water Excess} = 500 - 100 = 400 \text{ m³} \]
Importance
Understanding free water excess is crucial in reservoir engineering and hydrology to assess the amount of recoverable water from a reservoir. It aids in effective water management and extraction planning.
Common FAQs
-
What is free water?
- Free water refers to the water that is not bound to the rock and can be easily extracted from a reservoir.
-
How is connate water different from free water?
- Connate water is the water that is trapped in the pores of a rock and is usually not recoverable, while free water can be easily extracted.
-
Why is it important to calculate free water excess?
- Calculating free water excess helps in determining the amount of usable water in a reservoir, which is essential for planning extraction and water management strategies.
