Practical workflow
- 1
Confirm whether pressure and temperature inputs must be absolute before entering PVT values.
- 2
Use Bg calculators when converting gas surface volumes to reservoir volumes or vice versa.
- 3
Use Bo calculators when reservoir oil volume and stock-tank oil volume need to be reconciled.
- 4
Treat quick correlations as screening tools unless they have been calibrated against fluid-sample or equation-of-state work.
