Geomechanics and FracturingNaturally Fractured Reservoirs
Fracture Permeability from Hydraulic Aperture Cubic Law Formula
Fracture Permeability from Hydraulic Aperture Cubic Law calculates single-fracture permeability for naturally fractured reservoirs workflows in geomechanics and fracturing.
How engineers use this formula
Use this formula when the listed inputs (b_h_mm) are known and the assumptions behind the cited naturally fractured reservoirs relationship match the engineering case being checked.
Assumptions
- Input values are representative for the well, reservoir, fluid, or equipment case being evaluated.
- The declared units match the field-unit constants used in the formula.
- The cited formula applies to the selected petroleum engineering workflow.
Limitations
- The calculation does not replace a full engineering model or operating procedure.
- Accuracy depends on the source correlation, assumptions, input quality, and unit consistency.
Common mistakes
- Mixing unit systems without converting the inputs.
- Using default example values as field recommendations.
- Applying the formula outside the source assumptions.
Default example
Using the default inputs, k_f_mD equals 844,374.971523 mD.
