DYNAMIC MODELLING AND MULTIPHASE FLOW OPTIMISATION–GARANTEUR OF SAFE AND SECURE HYDROCARBON PRODUCTION.

These days petroleum and condensate formations, especially offshore ones, are actively being developed. The main feature of such formations is multiphase flow in tubing and riser. During production flow liquid slugs, adverse pressure pulses, and often hitting impacts are detected as a result of high gas content, interphase tension forces and complicated pipeline geometry, leading to pressure surges. The energy and very functioning efficiency of both gaslift and fountain operated wells is thus drastically reduced with the disturbance of the optimal production regime. In this paper it has been determined that a novel approach to multiphase flow management allows for decrease in emergency failures and operational expenses. Thus, right modelling and optimization of phase slippages can become a good guaranteur of safe and secure well operations. [ABSTRACT FROM AUTHOR]
