Calculation method
Calculation method
Core recovery (%)
Recovered length/drilled advance ×100; no RQD or fracture-quality inference.
Unrecovered interval (m)
Recovered length/drilled advance ×100; no RQD or fracture-quality inference.
Symbols and units
- a
- Recovered core length (m)
- b
- Drill advance (m)
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions & limits
Assumptions & limits
- User-supplied measurements and assumptions; Recovered length/drilled advance ×100; no RQD or fracture-quality inference. Supported limits: Finite numeric values bounded to 1e9 magnitude; lists and tables contain 1–100 records unless a stricter bound is stated. Inputs use the units shown. Lists explicitly paired by a method must have matching lengths; independent polynomial coefficient vectors may differ. Respect stated physical, interpolation, policy and computational domain limits.
