Introduction
This course focuses on the fundamentals and modeling of multiphase flow in pipelines and wellbores, including the definition of variables in multiphase flow, a detailed examination of the procedure of pressure and temperature profile calculations, fluid physical properties including gas, oil, water, and liquid phases physical properties determination in compositional and non-compositional (black-oil) models, VLE calculations and equations of state. In this course, flow regime determination, liquid hold-up, and pressure drop prediction empirical and mechanistic models in horizontal, vertical, and inclined flow conditions and some other special cases, e.g., downward vertical flow, flow in the annulus and flow in riser pipes will be discussed in details.
Objectives
- Describe the problems of water in natural gas systems
- Identify hydration types and structure of hydrates
- Describe the hydrates and dehydration processes in natural gas systems
- Perform the calculation of water contents in gas composition that can cause hydrates formation
- Troubleshoot the facilities once the hydration occurred
- Design and select proper equipments or processes for the dehydration unit.
At the end of the course, the delegates will be able to:
Training Methodology
This is an interactive course. There will be open question and answer sessions, regular group exercises and activities, videos, case studies, and presentations on best practice. Participants will have the opportunity to share with the facilitator and other participants on what works well and not so well for them, as well as work on issues from their own organizations. The online course is conducted online using MS-Teams/ClickMeeting.
Who Should Attend?
Oil & Gas Petroleum, Production, and Process Engineers.
Course Outline
