... data from nine fields to demonstrate the accuracy of cubic EOS's ability to predict JT cooling out of the box and with tuning. The cubic EOS was modified to shift the enthalpy curve to improve the JT cooling prediction across the choke. For this study, the measured pressures and temperatures before...

Post fracturing, production logging was carried out in Well A at two different chokes to understand flow behavior in wellbore and correlate with reservoir response. Based on these results, an intermediate choke was selected for production logging...

... disposal are well proven for surface facilities. For example, the wellhead desander, located upstream of the choke, effectively separates sand from the multiphase well flow and can be marinized for subsea use. However, the crucial question is "What to do with the sand?" This white paper provides a focal...
