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,...
Certain oilfields and recovery methods are sensitive to thermal gradients between the formation and injected/produced fluids. Examples include:
To reduce unwanted heat transfer, Operators may install Vacuum Insulated Tubulars (VIT); however, VIT technology poses several challenges that are...

Video #4: Considering Line Failure History
This course will provide attendees with an overview of the considerations, key factors, industry guidelines and practices, examples, and field experience related to the design and integrity of thermal recovery wells.
The objective of this course is to review the:
C-FER uses Monte Carlo simulation and statistical models to consider the uncertainty in all of your data. Below is a basic implementation of Monte Carlo simulation used to evaluate the burst pressure of corrosion features.
Set the size and sizing accuracy of a corrosion feature and see how the simulated burst pressure distribution compares to the nominal deterministic value. You can also modify the burst pressure model and the number of simulations ran.
C-FER can leverage historical data to assist in identifying potential threats to your assets. Interactive, web-based visualizations allow you to make quick and meaningful insights based on your data or the results of C-FER’s assessments. The following visualization explores PHMSA Incident data. Use the slider to adjust the charted year from 1968 to 2019. Incidents are categorized based on their product, type and cause. Significant shifts in the data can be seen over years with changing...
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...
Spirally welded pipelines (extensively used in liquid transmission pipeline systems) may contain manufacturing anomalies that are susceptible to fatigue growth. To account for the angle of these cracks with respect to the longitudinal pipe axis, modifications to inputs of crack assessment models are required.
Using the widely-used pipeline assessment model CorLAS®, we worked with Enbridge Pipelines to investigate two input modifications:
The pipeline industry has established various methodologies to estimate corrosion growth in pipelines. However, growth of corrosion feature length is inconsistently addressed in these methods.
We worked with Enbridge Pipelines to review these methodologies and determine the impact of feature length on corrosion burst pressure predictions.
This review:
A limit states design approach has been developed for geotechnical loads using a strain-based design format. This approach addresses the high level of uncertainty associated with the loading processed, which has limited the availability of design guidance in the past.
Working as part of a joint industry project, we have carried out a project to calibrate risk-consistent limit states checks that can be used for a range of strain demand and capacity distributions applicable to geotechnical loads.
