Welcome to the Crude Oil Quality Association!

The Crude Oil Quality Association (COQA) is dedicated to the belief that maintaining the integrity and consistency of the refining characteristics of crude oil streams is of importance to all parties involved in crude oil activity, from production locations to the refinery.

To this end, we hold three meetings annually.  These meetings are open to the public and we welcome your attendance and involvement.

    Meeting Archives Here

    From June 7- 10, over 100 professionals gathered in Edmonton, Alberta, Canada for the 5th joint international meeting of the Canadian Crude Quality Technical Association (CCQTA) and the Crude Oil Quality Association (COQA).

    The activities kicked off Tuesday afternoon with 40 participants taking advantage of an optional tour of three of the area’s top industry related facilities-
         - the Leduc #1 Energy Discovery Center
         - Kinder Morgan’s new rail facility, and
         - Suncor’s Edmonton refinery.

    Wednesday and Thursday were filled with excellent presentations ranging from broader topics such as “The Outlook for Canadian Oil Sands” and “Can Canadian Heavy Barrels Compete in the Gulf?”; to midstream issues regarding transportation of hazardous goods and compliance with the new DOT regulations; to more specific issues pertaining to the processing of partially upgraded bitumen, refinery pre-heat fouling, and spectroscopic and chromatographic analytical approaches to crude oil characterization.  Eric Vetters of ProCorr Consulting Services presented a nice overview talk on “Factors to Consider when Developing a Crude Quality Program” and the CCQTA shared updates on their on-going projects.

    Friday morning featured COQA subcommittee meetings, the most significant of which was the Domestic Sweet/ WTI subcommittee, headed by Aaron Dillard.  Work is progressing towards the creation and implementation of a standardized testing program for this very important mid-continent grade.

  • Concerned About Asphaltenes in Domestic Sweet? Join the new COQA Project!

    by Bill Lywood | Dec 10, 2015
    Due to growing concerns about asphaltenes in WTI/Domestic Sweet crude oil, a COQA sponsored project has been initiated, and is soliciting participation.  The project is structured to allow ANY and ALL interested parties to submit samples of their choosing to the same firm for testing.  All samples will be analyzed by Irv Wiehe and Soluble Solutions, an internationally recognized firm in this field.  A group discount will be applied and the submitting companies will be individually charged for their work.

    The benefits- Results will be provided to the submitting companies, who will then pass on only the sample dates, locations, and results to Dennis Sutton of the COQA.  Results will be gathered and shared collectively, thus preserving any proprietary information, while providing a tremendous cost effective benefit to participants and industry.  For more information, contact project leader Ron Fisher of BP at
