Description
An equivalent circular drainage radius describes the radius of a circle with a separately assessed effective drainage area.
An equivalent circular drainage radius describes the radius of a circle with a separately assessed effective drainage area.1
It does not reconstruct the reservoir's actual boundary geometry.
When to use Petroleum Drainage Radius Calculator
Use this tool to apply the stated petroleum drainage radius calculator operation with an explicit input and unit basis.
How to use Petroleum Drainage Radius Calculator and how it works
- Establish the measurement basis and units described above.
- Enter callerIndependentEffectiveDrainageArea and run the tool.
- Read result.value using the output meanings below.
- If input is rejected, correct the stated type, range, ordering or alignment issue and rerun; review successful results under the declared convention.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| callerIndependentEffectiveDrainageArea | Effective drainage area, on the basis specified in the algorithm. | number | required; finite; nonnegative; further conditions in the algorithm |
Require nonnegative effective drainage area. Divide by π and take the square root; the output length unit follows the square-area input unit.
radius = √(area / π) Apply the declared units, ordering and branch conditions.
| Output field | Meaning | Value type |
|---|---|---|
| result | Object containing the declared output fields. | object |
| result.value | Equivalent radius in the square root of the area unit. | number |

}Limitations and assumptions
The output applies the declared operation to the values you supply. Establish the measurement basis, units, coefficients and any caller-selected rules before interpreting it. The tool does not independently collect or verify observations or decide whether a model or reference applies.
Supply explicit required fields with the documented types and dense aligned arrays. Unknown fields, wrong types and nonfinite numbers are rejected. Branch-specific constraints are explained above. A successful false boolean, negative signed difference, empty slice or unresolved tie is distinct from an input error. Very large inputs or outputs may be rejected by shared resource limits.
Alternative or Complementary methods
For a related operation, use Petroleum Well Test Radius Of Investigation Calculator. A well-test investigation-radius reference depends on flow regime, storage, geometry and the chosen interpretation criterion.
For a related operation, use Petroleum Hydrostatic Pressure Calculator. Hydrostatic gauge pressure is the pressure increment from a vertical fluid column.
