Inflow-Control-Devices for Conventional Reservoirs

Disciplines: Production and Operations

Course Description

This 1-day course is an introduction to design and optimization of Inflow-Control-Devices (ICDs) in horizontal wells in conventional reservoirs. The gas-breakthrough and water-cresting/coning is the main reason of failures during such operations. The following topics will be covered:

  • Different types of the Inflow-Control-Devices defining their characteristic curves, and Operating Principles of ICDs
  • The formulation and physics govern restriction-style (Nozzle and Orifice) and channel-style (frictional) FCDs are presented. 
  • Understanding the PVT of the conventional reservoirs and calibration of the PVT
  • The review of Previous Use of the Inflow-Control-Devices: pros and cons.
  • Erosion Analysis, how computational fluid dynamics (CFD)
  • Understanding the Critical flow in orifice and venturri.
  • Dragging forces on sand particles: Lagrangian approach. 
  • Different types of Inflow Performance Relationship (IPR)
  • Reservoir/well coupling
  • Uncertainty Analysis: Segregated flow, virtual roughness

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

  • Become familiar with fundamentals of multi-phase flow in pipe
  • Be able to read and understand the ICD characteristic curves
  • Be able to optimize a ICD for a given producer
  • Be able to carry out simple nodal analysis for conventional producer

1 Day

Why Attend

Recently introducing inflow control devices (ICDs) as a new method to optimize well operations, there is an extensive need to predict the production performance considering the production constraints and flow restrictions across chokes and orifices in ICD. This course presents the fundamentals of reservoir modelling and ICD challenges.

Who Attends

Production engineers, reservoir simulation engineers need to model inflow control devices (ICDs). And technology development leaders that are involved in implementation of ICD.

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.


0.8 CEUs are awarded for this 1-day course.

Mazda Irani is acting as a CTO of Ashaw Energy. 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.
