Update on C-FER's COVID-19 Response

Monday, March 23, 2020

Message from Francisco Alhanati, Managing Director

Operational Continuity and Contingency Plans

At C-FER, we are strictly following the recommendations of our local health authorities to manage the situation created by the COVID-19 outbreak. Keeping the health and well-being of our employees, their families, our clients, and the community at large is our top priority.

Recent travelers and personnel with vulnerable health conditions were identified during the early stages of the alert. A self-isolation policy was promptly implemented. Special safe-work protocols were defined to minimize exposure of people on site and mitigate the likelihood of...


Learn about C-FER's sour service capability

Friday, March 6, 2020

Overview of our special environments laboratory

Correct qualification and material selection is even more important when equipment is exposed to H2S-contaminated or other sour gas atmospheres.

These environments are both highly toxic and corrosive.
Many materials and products are susceptible to hydrogen embrittlement and stress corrosion cracking. The risk of catastrophic failures significantly increases.

C-FER provides clients with a wide range of sour service testing capabilities that help to understand and minimize various failure mechanisms.

Our Special Environments Laboratory, is one of the world's largest and most comprehensive...

How engineering analysis and field run-life data can be coupled to predict the effects of wellbore curvature on ESP reliability
paula.kreba Thu, 02/13/2020 - 14:15

C-FER’s Craig Radke is presenting at the 2020 SPE Symposium: ESP Journey to the Future.

During the presentation, Craig will discuss how wellbore trajectory, reserve recovery and productivity can be considered in combination to optimize ESP designs and improve the run-life of ESPs in horizontal wells.

The presentation includes a case study on how a combined physics-based and data-driven analysis approach was applied to ESP-lifted fields. Craig will explain how finite element analysis and field reliability data analysis methods were used to correlate the calculated housing stress and curvature...

How to enhance tubular connection product line validation

Development of Sealability Evaluation Criteria and Performing Parametric Finite Element Analysis (FEA)


Industry has made efforts to establish a framework for the tubular connection product line verification in terms of the structural integrity and sealing capacity for high pressure/high temperature and thermal recovery wells. However, these frameworks are a work in progress.

In consideration of improving the confidence in the interpolation and extrapolation methods presented in the current standards and of applying the quantitative element analysis (FEA) methods to qualitative evaluation, Jueren Xie of C-FER Technologies and Junfeng Xie of PetroChina have completed parametric FEA case...

Risk-ranking thermal wells for integrity
paula.kreba Thu, 08/29/2019 - 16:46

In collaboration with Devon Canada (now CNRL), we developed a tool to quantitatively risk-rank SAGD wells for subsurface barrier integrity based on identified damage mechanisms and associated, readily available influential attributes or proxy attributes.

Such a tool can aid significantly in identifying wells at a higher risk of casing and cement sheath damage or failure; the specific mechanism and barrier at risk; the associated diagnostic, mitigation steps and resources to deploy to achieve optimal benefit; and a means to support the transparent identification, communication and tracking of...

How flow control devices may benefit Geothermal Applications
paula.kreba Thu, 08/29/2019 - 16:25

This year, C-FER will be presenting a paper entitled, An Introduction to Flow Control Devices and the Potential Benefits to Geothermal Applications.

Geothermal operators face several significant challenges in creating and maintaining optimal production from their wells. One of these challenges is the uniform distribution of both injected and produced fluid to and from the reservoir. Preferential production of fluid from one zone of a reservoir can result in thermal drawdown, reducing the temperature of the produced fluid. Additionally, the formation of direct pathways between injection and...

How to optimize SAGD production with AICV
paula.kreba Thu, 08/29/2019 - 13:16

Flow control devices are used in SAGD wells to balance the oil inflow along horizontal wells and mitigate unwanted fluid breakthrough.

The newest generation of flow control devices for SAGD wells, Autonomous Inflow Control Valves (AICVs), can:

  • optimize oil production;
  • reduce SOR; and
  • significantly restrict the inflow of unwanted fluids.

To assess the performance of AICVs, we conducted testing in a full-scale high temperature laboratory flow loop that replicates SAGD production conditions. Details of the test program, and the principles that make up the AICV technology, are presented in a...

How a new FCD can optimize thermal SAGD operations
paula.kreba Tue, 08/27/2019 - 13:13

As part of a Joint Industry Project focused on studying FCDs for SAGD operations, a new device was investigated that inhibits the influx of steam while allowing the flow of emulsion into a production well. This new device was tested in C-FER’s lab using a high temperature, multiphase FCD flow loop and a three-phase FCD erosion loop, and in the field at Cenovus and Suncor sites. Details of the test program and the performance results of the new FCD device are presented in a paper co-authored by Daniel Booy.

The paper will be presented at the upcoming SPE Annual Technical Conference and...

How to use fiber-optic sensors to validate FCD performance
paula.kreba Mon, 08/26/2019 - 13:11

As part of a Joint Industry Project focused on optimizing FCD design and selection, fiber-optic based instrumentation was deployed in FCD-equipped SAGD producer wells to collect distributed temperature and acoustic sensing data to better understand the fluid inflow distribution.

In addition, acoustic instrumentation was installed in parallel with a high temperature, multiphase flow loop located at C-FER to try and better understand the correlation between an FCD’s operating condition and its measured acoustic response. Details of the test program, including observations from the lab and field...
