What were the top takeaways from Dr. Wayne Monnery’s oil blending webinar? With over 100 viewers between Canada & the USA, the webinar was a great success. Thanks to everyone who attended – we hope that you’ll join us in the next digital SIGIT ACADEMY classroom!




  • When blending crude oil, if you’re solely relying on a simulator, proceed with caution.
  • Heavy crude oil blending is an economic way of meeting specifications for pipelining/treating.
  • Design/operation calculations can be tricky unless all required specifications are measured.
  • RVP should be determined in the lab if possible–simulators/manual calculations alone are not always reliable.
  • Reduce your risk by checking simulator data with manual calculations. You need to make SURE that your simulator is accurate; not just assume it is.
  • Simulator blend density values should be checked against manual shrinkage calculations. Simulator blend viscosity values are not recommended, use manual blend calculations.
  • Asphaltene precipitation should be checked either in a lab or with a simulation at a minimum.
