Analytical Models for Thermal Recovery and Their Assumptions and Limitations (Forecasting and Prediction)

---

Disciplines: Reservoir

Course Description

This 1-day course is an introduction to all analytical models assumptions and mathematical principles and their limitations and also discusses. In this course there will be examples using Excel spreadsheets. In this course solvent applications are not covered, but there is 10% of the course on CHOPS.

Topics:

• Thermal Operation: The course starts with short definition of SAGD, CSS and Steam-flooding and how different stage of it will be operated.
• Heat Transfer: Heat-transfer mechanisms are pivotal to the thermal process. In this section different temperature models and their consideration with respect to conduction and convection are discussed:
  • Marx-Langenheim
  • Butler Temperature Model
  • Sharma Gates Convection Model
  • Irani and Ghannadi Convection Model
• Butler Production Model: The derivation of oil production using Butler is discussed. Finally, assumptions in “Original Butler model”, TANDRAIN and LINDRAIN models will be discussed and evaluated:
  • Butler Plateau Model (i.e., “Original Butler model”, TANDRAIN and LINDRAIN)
  • Butler Ramp-up Model
  • Discussion on Steam Interface Velocity in “Original Butler model”, TANDRAIN and LINDRAIN models, and its comparison to field data.
  • m exponent factor discussion
• CHOPS Production Model
  • Skin-Damage Modified Model
• CSS Production Model:
  • Boberg and Lantz Model,
  • Tamim and Farouq Ali Model
  • Irani Model
• SAGD-SOR Discussion: Heat conservation concept and the basis of different SOR analytical models are presented:
  • Reis SOR Model
  • Edmunds and Peterson (2007)
  • Miura and Wang (2012) Model

Learning Objectives:

At the end of this course, participants will be able to:

• Understanding heat transfer in SAGD operation.
• Understanding limitations of analytical models.
• Assumptions made in analytical models.
• Optimizations made in forecasting models.

Introductory to Intermediate

Course Length

1 Day

Why Attend

Most thermal operators are highly dependent on analytical models for their forecasting on both oil production and SOR predictions. This course briefly discusses limitations and assumptions made on different models and provides a good understanding on different models and how to modify these models.

Who Attends

Reservoir and Production Engineers that are involved in forecasting and evaluation of SAGD projects. This is a fundamental course for Reservoir Engineers new to Thermal Operation.

Special Requirements

Attendees should bring a laptop with Excel installed
