Principles of Well Performance; Artificial Lift and Gas-well Deliquification


Production and OperationReservoir Descriptions and Dynamics

Description

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 2 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.

Learning Level

Introductory/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 Should Attend

  • 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. 

CEUs

1.6 CEUs (Continuing Education Units) will be awarded for this 2 day course.
