Production Forecasting for Low Permeability Reservoirs

INSTRUCTORS: W. John Lee PhD
Discipline: Unconventional Reservoirs, Engineering
Course Length (days): 2
CEUs: 1.6
Public/ In-house/ Both: Public & In-House
Who Should Attend:

Engineers, geologists, financial analysts, investors, bankers, or anyone who needs to understand traditional and recent methods to forecast production for low-permeability oil and gas reservoirs.

Course Description:

This course summarizes decline curve analysis (DCA), including Arps’ decline models, linear flow models, and other recent decline analysis approaches. We provide background information on basic fluid flow theory, which enhances understanding of strengths and limitations of both traditional and recent decline analysis methods. Numerous short class exercises illustrating principles will be included.

LEARNING OUTCOMES:

  • State assumptions and limitations of Arps and other decline models
  • Analyze production histories and forecast production using Arps and other decline models for low-permeability reservoirs
  • Analyze production histories and forecast production using the Fetkovich type curve
  • Outline systematic forecasting procedures combining rate-transient analysis (RTA), decline curve analysis, numerical and analytical reservoir models
Course Content
  • Basic fluid flow fundamentals underlying DCA and RTA
  • Flow regime identification
  • Arps decline model
  • Fetkovich and other type curves
  • Alternative decline models: stretched exponential, power law, long-duration linear flow, Duong model
  • Comparison of decline models
  • Systematic procedure for DCA
  • Overview of RTA, including systematic work flow for applications
