SPEI: Production Decline Analysis for Unconventional Reservoirs

Register here.

Attendees will receive a comprehensive methodology for well performance analysis with specific focus on unconventional oil and gas in this course. The approach combines the use of several powerful techniques and will illustrate the practical aspects of production data analysis.

Participants are encouraged to bring their own data, as time will be allotted to go through their examples as a class. Depending on interest and time available, examples from Barnett, Bakken, Montney, Horn River, Marcellus, Haynesville, and Eagle Ford plays will be presented. Laptops are required for this course. Course materials will be distributed via USB drive.

Topics Covered

  • An introduction to well performance analysis
  • Linear flow analysis for tight fractured reservoirs
  • Simplified approach
    • Log-log diagnostic plot—identifying flow regimes
    • Specialized plot—determining LFP and skin
    • Flowing material balance analysis—determining SRV
    • Modified hyperbolic decline curves
  • History matching using analytical and numerical models
    • Modeling performance of horizontal wells with multiple fractures
    • Pressure dependent permeability
    • Adsorbed gas

Students must bring laptops to class. Basic Windows navigation skills are recommended. Software will be provided.

Learning Objectives

  • Critically assess data quality and perform qualitative diagnostics on well production data
  • Identify well and reservoir flow regimes from rate/pressure response
  • Estimate reserves, OGIP/OOIP, and drainage area
  • Determine “linear flow parameter” and skin
  • Forecast production with particular focus on the inherent uncertainty in unconventional plays
  • Assess well performance and identify optimization candidates

Who Should Attend

Engineers and technologist involved in the exploitation, production, and evaluation of tight and unconventional reservoirs. All oil and gas professionals that need to get more from their production and flowing pressure data.
