Multiphase Flow Model of Gas Hydrate Production …
Scholars have carried out a lot of research on multiphase flow in wellbore. Most of them are based on steady-state flow theory, and have developed three types of multiphase flow models, including homogeneous flow model, split phase flow model and drift flow model, by using laboratory test and field test data and combining with empirical …

Should I use dolomitic or calcitic lime?
The basic question is: Is magnesium build-up from use of dolomitic lime a problem? The short answer? Very unlikely. Calcitic lime is derived from deposits of primarily calcium carbonate. Dolomitic lime is derived from deposits of calcium carbonate combined with magnesium carbonate and contains much higher levels of magnesium.
