Onshore Gas Gathering Systems: Design & Operations - PF-45

Petroskills Registerbutton
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.

Production & facilities department engineers/senior operating personnel responsible for the design, operation and optimization of onshore gas gathering systems and their associated field facilities.

You will Learn:

  • The impact of gathering system pressure on gas well deliverability
  • The impact of produced fluids composition on gathering system design & operation
  • Evaluate field facility & gathering system configurations for different applications
  • Recognize and develop solutions to operating problems with existing gas gathering systems
  • Use a commercial simulator to optimize different gathering system options and size flowlines/trunk lines
