Background
In 2010, the CCQTA discussed the development of Crude Quality Tutorials designed to help educate and train CCQTA members and to provide a general overview of crude quality issues for use and distribution to uninformed audiences. In the 2011, a presentation was developed to address the latter, while the former remained on the Association’s work item list.

In March 2021, the CCQTA launched the "Centre of Learning" on the CCQTA website. This new initiative was started as an effort to find new ways to engage with our existing members as well as summarize historical information for new members. This should allow new members to get up to speed quickly and engaged in new discussions. Content is targeted at 25-40 minutes to fit into a typical lunch hour.

Several formats are planned including:

• Presentations
  
• Panel discussions
  
• Interviews
  

• Light Ends and Vapour Pressure (2 episodes)
  
• Crude Oil Stability/Compatibility & Blending Practices (2 episodes)
  
• H₂S in Crude Oil
  
• What is the CCQTA – An Introduction
  
• Chlorides in Crude Oil
  

1. The Vapour Pressure series launched in March 2021 and was released publicly. The first episode is focused on the basics of vapour pressure including theory, terminology and applications. Vapour Pressure - Episode 2 was released in August 2021 is focused on sampling and testing methods impacting vapour pressure. Both episodes are available publicly.



2. The "Crude Oil Stability, Compatibility & Blending" series launched in October 2021 and is in our member’s catalog. Episode 1 focused on the following:
   
   
   
   • Hydrocarbon Structural Basics & Classification (SARA)
     
   • Solubility and Stability Related to SARA — CII
     
   • Blending predictions using SARA & CII
     
   • Solubility Testing by D8253
     
   • Relationship between CII and P₀
     
   • Blending predictions using D8253 solubility parameters
     
   • CII and solubility parameters in blending operations
     
   
   



3. Episode 2 of the "Crude Oil Stability, Compatibility & Blending" Lunch and Learn Series was released on Feb 2022 is in our members catalog. This is the second episode in this series. This episode of this series discusses the following:
   
   
   
   • Review of Episode 1 including how the SARA impacts asphaltene solubility.
     
   • Asphaltene Stability, its dependence on the SARA ratios and how they impact the asphaltene micelle.
     
   • An in-depth tutorial of the ASTM D8253 solubility measurements.
     
   
   



4. H₂S in Crude was released in August 2022 and was released publicly. This Lunch & Learn focuses on the following:
   
   
   
   • H₂S basics
     
   • CCQTA background with H₂S
     
   • H₂S in crude sampling and measurement
     
   • H₂S control methods
     
   
   



5. What is the CCQTA – An Introduction was released publicly in February 2023. This Lunch & Learn is an introduction to the CCQTA for prospective members and as a way for existing members to introduce their colleagues to CCQTA. This episode features the following:
   
   
   
   • Origins and founding guidelines:
     
   • Project structure
     
   • Director testimonials
     
   • Synopsis of key projects
     
   
   



6. Chlorides in Crude Oil was released publicly in October 2023. This Lunch & Learn focuses on the following:
   
   
   
   • Types of chlorides
     
   • Sources of chlorides
     
   • Corrosion and fouling issues
     
   • Test methods and their nuances
     
   • Experiences and cautionary notes
