Principles of Gas Well Performance and Deliquification


Production and Operation Reservoir Descriptions and Dynamics

Course Description

Learning Objectives:
To present a practical refresher on the fundamental principles of gas well performance and demonstrate how these underpin production system design and optimization. To examine liquid loading effects and deliquification options.

Outline:

  • Overview of Inflow and Outflow or liquid lift concepts for gas wells.
  • Estimating IPRs from well test or offset well data and reservoir studies.
  • Gaswell Outflow Performance and Liquid Lift or Hold-up expectations.
    • System backpressure effects and management options.
    • Gas production forecasting and performance monitoring.
    • Integrated Production or Asset Models (IPM/IAM).
  • Discuss the impact of Skin effects on gas-well performance.
  • Review liquid loading risks, impacts and mitigation options.
  • Examine application areas for various gas-well deliquification options.
  • Perform an exercise to screen production enhancement opportunities.
  • Review the challenges in modelling and/or cleaning-up tight gas wells.
  • Discuss reference books and software packages.

Format and Requirements:

  • This two-day training course will include:
    • 65% Lectures to introduce the concepts and commonly used methodologies
    • 25% Consortium style team problem solving exercises
    • 10% Class discussions
  • The Group Exercise provides an opportunity to practice project team organization, participation, facilitation, and presentation skills. 
  • Exercises can be completed with a hand held calculator, tablet, or laptop. 

Learning Level

Introductory to Intermediate

Course Length

2 Days

Why Attend

At current gas prices, production optimization is a key focus for many asset teams. This refresher is intended to provide a pragmatic approach to identifying opportunities to add value with relatively low cost projects offering a rapid payback and/or a justification for additional well test data collection.

Who Attends

  • Reservoir; Production and Well Engineers or Technologists with 6 – 60 months experience
  • Production and Well Service Supervisors wanting a refresher on the engineering principles
  • Geo-scientists and production data management specialists seeking cross-disciplinary training

Special Requirements

Hand held calculator, tablet, or laptop.

Instructor

Bob Pearson is a subsurface advisor to oil and gas companies and investors. He is a former SPE Distinguished Lecturer on Optimized Gas-well Completions and Operations and a Board Member of the Calgary Section.

From 1970 to 1980, Pearson worked for Shell International in S.E. Asia and The North Sea. He then moved to Petro-Canada (now Suncor) in Calgary. Since 1983, he has worked as a consultant, through RPS Energy and a predecessor company (APA Petroleum Engineering, which he co-founded). In 2012, he co-founded Tactical Gas Services Pty. Ltd., a consulting firm providing advisory services on Unconventional Gas Exploration and Development in the Australia Asia Pacific Region and North America. In 2015, he moved back to Canada, where he recommenced his consulting and training services through Glynn Resources Inc.

Pearson has a BSc. (Hons) in Mining Engineering from the University of Newcastle-upon-Tyne in the U.K. and is a registered Professional Engineer in Alberta. He has been an active member of SPE since 1975.
