Computational Fluid Dynamics

C-FER is proud to be participating in the Alberta CFD Users Meeting on June 3, 2019.

This workshop is sponsored by our parent company, Alberta Innovates, and focuses on the challenges and opportunities of CFD adoption in the Alberta economy.  Attendees will have the opportunity to hear from presenters in Alberta's key industries and take part in an open forum.

The Industry Challenge

Several Steam Assisted Gravity Drainage (SAGD) operators have observed flow instabilities in their Electrical Submersible Pump (ESP) produced wells, commonly resulting in the complete loss of fluid flow to surface. In some wells these instabilities appear without any apparent precursor signs or indications of a potential flow disturbance, while in other wells there are clear indications of gas entering the pump (e.g. evident by flow and current fluctuations).

In many cases...

Course Overview:

This course will provide attendees with an overview of wellbore thermal-hydraulics (i.e. coupled thermodynamics, heat transfer, and fluid flow).  Additionally, they will gain a greater understanding of technologies and analytical methods currently for SAGD thermal-hydraulic applications.

The objective of this course is to:

  • Provide an overview of the physics and thermodynamics associated with the design and performance of the injection and production wellbores in these...

The Industry Challenge:

Pressure transients can damage complex flow systems by mechanisms such as hydraulic hammer and cavitation. These transient conditions can occur during normal operation of the system or during unplanned, emergency shut down events.

Comprehensive models of the fluid rheology, as well as dynamic analyses of pressure wave propagation, are required to understand the conditions that lead to transient events and how the resulting event could impact the performance and integrity...

Abstract

High rate injection or production of fluids with sand particles places wellhead components and downhole assemblies at risk of erosion damage. Depending on the severity and location of the material loss, this may pose a significant well loss or blow-out hazard. For this reason, assessment and mitigation of erosion can be critical for such applications.

In this work, Computational Fluid Dynamics (CFD) was used in conjunction with erosion models to assess the erosion damage...

The Industry Challenge:

The ability to predict gas and liquid flows is essential in the energy industry. Such flows might be in a reservoir, through wells and pipelines, in tanks, or throughout various processes.

When these flows are complex and difficult to characterize with analytical or empirical models, Computational Fluid Dynamics (CFD) can provide the answer.

How We Help:

A large number of calculations are performed allowing a variety of flow parameters to be quantified and visualized,...

C-FER integrates a variety of advanced analysis tools to model the performance of complex structures, equipment and operating environments. This includes using Finite Element Analysis (FEA) to model the structural performance of equipment, Computational Fluid Dynamics (CFD) to evaluate flow, erosion and heat transfer and risk and reliability analysis to evaluate the likelihood and consequences of failure.

Often there is some uncertainty with aspects of the system being analyzed such as...

The Industry Challenge:

Predicting flow behaviour is becoming more critical as Operators strive to control costs and ensure safe operations. The introduction of processes such as multi-stage hydraulic fracturing, downhole flow control devices and oilsands tailings management are increasing the scale and complexity of flow analysis.

Many of these new applications include multi-component, multi-phase liquids that might have shear rate and temperature dependencies that make it difficult to...
