Geology Acid Fracture Conductivity Calculator
Ideal etched unpropped channel cubic conductance with independently measured closure retention/channel area, not proppant k×width or acid-treatment efficacy. Caller independently establishes matching units, evidence, method edition and applicability; output is not compliance, diagnosis, work-safety approval, geological identity or validated hazard prediction.
Description
Residual fracture width after acid treatment can be combined with independently supplied areal contribution factors.
Residual fracture width after acid treatment can be combined with independently supplied areal contribution factors.1
A cubic aperture relation gives a conditional permeability–width contribution without modeling etching, closure stress or flow connectivity. Use this tool to calculate acid fracture conductivity from the supplied measurements and assumptions.
When to use Geology Acid Fracture Conductivity Calculator
Use this tool to calculate acid fracture conductivity from the supplied measurements and assumptions. Establish the measurement units, sampled interval, calibration or model edition and geological assumptions before entering data.
How to use Geology Acid Fracture Conductivity Calculator and understand its results
- Establish the measurement units, sampled interval, calibration or model edition and geological assumptions before entering data.
- Enter etchedChannelWidthsM, closureRetainedFractions, channelAreaFractions, using the field meanings and rules below, then run the tool.
- Read etchedParallelChannelConductivitiesM3. Interpret the fields using their units, signs and evidence conventions below.
- If input validation fails, correct the reported field and run again. Before applying the result, check reference scope, model assumptions and any missing evidence or placeholder values.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| etchedChannelWidthsM | Etched channel widths m | list of number | Required |
| closureRetainedFractions | Closure retained fractions | list of number | Required |
| channelAreaFractions | Channel area fractions | list of number | Required |
Enter nonempty aligned nonnegative etched widths, retained fractions in [0,1] and channel area fractions in [0,1]. Multiply width by retained fraction, cube it, multiply by area fraction and divide by 12. Return one m³ contribution per channel. The implementation does not require the area fractions to sum to one or combine contributions into a total.
channelConductivityM³_i=(widthM_i×retainedFraction_i)³×areaFraction_i/12 Use the exact units, boundary rules, ordering and missing-evidence conventions above.
| Output field | Meaning | Value type |
|---|---|---|
| etchedParallelChannelConductivitiesM3 | Etched Parallel Channel Conductivities M3; follow the units, sign, ordering and evidence convention stated above | list of number |

}Limitations and assumptions
A cubic aperture relation gives a conditional permeability–width contribution without modeling etching, closure stress or flow connectivity. Interpretation depends on the units, sampling scope and exact model described above.
All listed fields require explicit values. Unexpected fields, incorrect types, nonfinite numbers and sparse evidence arrays fail validation; the specific bounds and alignment requirements are stated above. Extremely large inputs or outputs can also be rejected. An input error is distinct from a successful result reporting false, no matches or missing evidence.
