CALCULATION REFERENCE

Analytical approach to production balances

These conversions use fixed factors and the relationship between API gravity and specific gravity at 60 °F. They do not include volume corrections for temperature, pressure or composition. For production balances and custody transfer measurement, consult our team about your operation's conditions and measurement procedures.
