Fracture Fluid Coefficient - Viscosity-Controlled Liquids Formula
Fracture Fluid Coefficient - Viscosity-Controlled Liquids calculates viscosity-controlled fracture fluid coefficient for hydraulic fracturing workflows in production engineering.
How engineers use this formula
Use this formula when the listed inputs (c_conv, k, DeltaP, phi_pct, mu_f) are known and the assumptions behind the cited hydraulic fracturing 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, C_v equals 0.014142 dimensionless.
