Injected Hydrocarbon Pore Volumes Formula
Injected Hydrocarbon Pore Volumes calculates injected hydrocarbon pore volumes for injection wells workflows in production engineering.
How engineers use this formula
Use this formula when the listed inputs (W_i, B_wi, A, h, phi, S_o) are known and the assumptions behind the cited injection wells 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, HCPV_inj equals 0.046956 pore volumes.
