Estimating oil density at operating temperature and pressure

[cmlpetro]

API gravity at standard conditions is known. Is there an easy way to estimate the gravity/density at operating conditions. In the range of -5 to 60 degree C and 250 to 5000 kPa.

Thanks.

There are many nomograms and curvers around in text book API and similar reference book. Just look/search/buy. These may not be very precise for your specific crude - but check out the assumptions and limitations yourself.

Best regards
