  • Course Content
This course deals with the design, operation, and optimization of onshore gas gathering systems and their associated field facilities, from the wellhead to the central gas processing facility. From a design perspective, the main variables that impact the flexibility and operational characteristics of an onshore gas gathering system will be discussed. Typical operating problems are covered including hydrates, multiphase flow issues, corrosion, declining well deliverability, etc. Exercises will be utilized throughout the course to emphasize the key learning points.


"Instructor was very open to sharing industry experiences and had excellent knowledge of the information. Class discussions on issues others have experienced was helpful for applicability of info." - Process Engineer, United States


"Great course. I liked how it brought reservoir, gas, and plant all together and showed how they interconnect." - Financial Analyst, United States
