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.

    Mid-Continent Issues Highlight Early 2016 Meeting

    Over 130 conference participants gathered at the historic Menger Hotel in San Antonio for the early 2016 COQA meeting.  On the morning of Wednesday, March 2, the COQA offered an optional wine country tour for attendees and guests to Grape Creek Vineyards.  Wednesday afternoon’s subcommittee meetings on Crude by Rail, WTI quality specifications, and Asphaltene Precipitation were lively, and well attended.  Dr. Bagawandoss (Intertek) provided an update on 49 CFR 173.41 regarding regulations pertaining to the transportation of crude by rail as well as truck and barge. 

    Thursday featured breakfast provided by the COQA followed by a full day of presentations.  A number of the talks addressed aspects related to mid-continent crudes, including:
         - Professor Tom Tunstall of University of Texas San Antonio describing the social and economic characteristics of the Eagle Ford,
         - Dr. Irv Wiehe presenting information on crude compatibility, and describing the current COQA project,
         - Ashok Anand of Enbridge updating the group on WTI Quality at Cushing as determined by Enbridge,
         - Jeff Hazle of the American Fuel and Petrochemical Manufacturers (AFPM) detailing refiners’ crude quality issues, and in particular with WTI, and
         - Jeff Kralowetz of Argus presenting “Crude Quality and US Spot Markets”.

    We are looking forward to the upcoming joint CCQTA/COQA in Edmonton, June 7-10.

  • 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
  • Crude Oil Characteristics Research

    by Bill Lywood | Jul 16, 2015

    Sandia National Laboratories, in support of the US Department of Energy (DOE), has published a working draft of a Crude Oil Characteristics Research Sampling, Analysis and Experiment (SAE) Plan, that, “contains recommendations on research needed to improve understanding of transport-critical crude oil and especially tight crude oil properties including:

    • Identifying the most appropriate sampling and testing methods for crude oils

    • Sampling, testing and compilation of data on different crude oils using those methods

    • Initial combustion testing to identify relationships between a particular chemical or physical property of crude oil, or combination of such properties, and combustion properties

    • Possible full-scale combustion tests”

    Thank you to David L. Lord (Sandia National Laboratories) and Richard A. Elliott (US Department of Energy) for sharing this information.
