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...

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

Thursday, August 29, 2019

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

Thursday, August 29, 2019

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

Tuesday, August 27, 2019

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

Monday, August 26, 2019

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...

What may be changing in Annex B of CSA Z662-2023?
paula.kreba Fri, 03/29/2019 - 09:50

CSA Z662 is the Canadian standard for oil and gas pipeline systems, with Annex B specifically focusing on how to perform risk assessments for pipelines. Annex B is currently under review by the Risk Management Task Force and will likely be undergoing significant changes in 2023 to include more guidance on performing risk assessments and quantitative risk criteria for both natural gas and liquid pipelines.

Task Force Chair Maher Nessim, and Task Force work group leaders Mark Stephens of C-FER Technologies and Shahani Kariyawasam of TransCanada, will be leading a work group session at the Banff...

C-FER is leading work group 5 - Management of Cracking Pipelines - at the 2019 Banff Pipeline Workshop

Management of circumferential cracks in pipelines has been a secondary concern to axial cracks, and integrity assessment techniques are not as mature as those available for axial cracks or those from other industries. In order to give industry members an opportunity to share their experiences and learn from other’s successes and failures, Mark Stephens of C-FER Technologies, together with Lyndon Lamborn of Enbridge and Elvis SanJuan of Riverol, will be leading a work group session on circumferential crack management at the Banff Pipeline Workshop.

Discussion is anticipated regarding...
