Thermal-Hydraulics Design and Optimization

Completions Completions

Course Description

This one-day course is an introduction to gas-liquid flow patterns in horizontal pipes for complex case of steam at saturated condition at injector; gas-lifting at producers and steam hammer envelopes are discussed. Different two-phase flow mechanistic pattern maps such as Taitel–Dukler (1976) and Kattan–Thome–Favrat (1998) models and empirical methods such as Beggs and Brill will be discussed.


  • Gas-liquid flow patterns: What is the difference between gas-water and steam-condensate?
  • Introduction to Steam Hammer: Does steam-hammer happen in producer or injector?
  • Liquid Pool modeling: Is conventional IPR suitable for SAGD producer?
  • Liner-Deployed FCDs modeling: How do you select proper FCD for a given SAGD asset?
  • Analytical modeling of steam circulation: When do you convert from circulation to SAGD?

Why Attend

Thermal operations such as SAGD are dealing with complex and dynamic of multiphase-flow. Having steam at saturation condition is yielding the condition different from conventional practices which solution gas acts as ideal gas. Recently introducing new completions such as flow control devices (FCDs), there is an extensive need to predict the production performance of SAGD processes considering the production constraints and flow restrictions across chokes and orifices in FCDs. This course presents the fundamentals of multiphase flow, liquid pool IPR, and FCD flow restriction and their interactions.

Upon completion of this course, participants will be able to:

  • Be familiar with fundamentals of multi-phase flow in pipe
  • Carry out simple nodal analysis for SAGD injector and producer
  • Make assumptions in different two-phase flow mechanistic pattern maps
  • Be familiar with fundamentals of steam trap control and minimum subcool concept
  • Understand benefits and limitations of implementation of FCDs for SAGD producer

Who Attends

This course is intended for production engineers, reservoir simulation engineers who need to model multi-phase flow in injector and producer, and technology development leaders that are involved in implementation of new completions such as FCD.

Special Requirements

Students will need laptops.
Participants should have understanding on one-phase flow such as its frictional pressure calculation.
Participants should have basic knowledge of Microsoft Excel.
Participants should have moderate experience or exposure to the topic.

Mazda Irani is the director of Ashaw Energy Ltd. He is currently engaged in the designing and optimization of Steam Assisted Gravity Drainage (SAGD) and proper near wellbore modeling for the SAGD wells. One of his main tasks is to help and develop a software that can help operators run their SAGD wells at optimum subcool, manage the hot spots, and modify their FCD design in heterogeneous reservoirs. He published a trilogy paper named “On Subcool Control in Steam-Assisted-Gravity-Drainage Producers"

Dr. Irani was previously employed in technical and supervisory roles with Cenovus Energy, Suncor Energy, RPS Energy, and C-FER Technologies. He has published and presented more than 40 technical papers on different aspects of SAGD operation. Dr. Irani holds a PhD in petroleum engineering (U of C 2017) and geomechanics (U of A 2012) and three Masters degrees in petroleum engineering, geotechnical engineering, and structural engineering.
