2-Nodal Analysis – Well Outflow


Product description

Well production mechanisms are one of the most important things to understand when working at optimizing your wells. Whatever if your well is in natural flow or if it uses artificial lift, mastering the concepts of inflow and outflow will allow you to understand any well behavior and optimize it.

This course focuses on the outflow mechanism. You will be guided to many key concepts like VLP curves, pressure losses, flow regimes, multiphase flow pressure correlations, nodal analysis…
Well performance, reservoir and petroleum engineering will be all linked. You will be shown how PVT parameters impact the production of your well.
Gas production will also be discussed through the concepts of critical velocity and liquid loading.
By following this course you will learn how to increase the production of your oil and gas wells.

This course connects reservoir engineering to well performance and petroleum engineering. Participants will acquire a good understanding of well outlfow mechanism.
Taken together with the Inflow Mechanism, it will teach what a senior petroleum engineer should know about nodal analysis and well production.
