| \( C_c \) = Cost of Coring | $ / ft | - |
| $ C_b $ = Core Bit Cost | \( \) $ | - |
| \( C_r \) = Rig Cost | \( \) $ | - |
| $ T_c $ = Total Coring Time | $hr$ | - |
| $ T_t $ = Trip Time | $hr$ | - |
| $ T_r $ = Core Recovery Time | $hr$ | - |
| $ F_c $ = Footage Cored | $ft$ | - |
| $ R_c $ = Core Recovery Percentage | $dimensionless$ | - |
