Practical workflow

  1. 1

    Confirm whether pressure and temperature inputs must be absolute before entering PVT values.

  2. 2

    Use Bg calculators when converting gas surface volumes to reservoir volumes or vice versa.

  3. 3

    Use Bo calculators when reservoir oil volume and stock-tank oil volume need to be reconciled.

  4. 4

    Treat quick correlations as screening tools unless they have been calibrated against fluid-sample or equation-of-state work.
