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.

  • 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”

  • COQA Mid 2015 Meeting in Minneapolis, MN

    by Dennis Sutton | Jun 23, 2015
    The mid-2015 COQA meeting was held June 10 & 11 at the Hyatt Regency in downtown Minneapolis, MN.  We appreciated the support of the local area refineries-Flint Hills Resources and Northern Tier Energy.

    Activities started with the Crude by Rail subcommittee discussion on Wednesday afternoon, June 10.

    The general meeting kicked off with George Shaffner, Senior Vice President of Marathon Petroleum's presentation highlighting the company's on-going projects. Cara Madee concluded the Marathon talk, describing the Utica oil, including physical characteristics.  Applications of Near Infrared spectroscopy to crude oil characterization were featured in talks by Colin Stewart of Intertek in Aberdeen, Scotland and Dr. Didier Lambert, President of TOPNIR. 

    The growth of the light, tight crude oil, particularly in the Bakken, has generated a great deal of interest on the part of our membership.  Dr. Arden Strycker of SGS described some of the analytical challenges while Ted Aulich of the Energy & Environmental Research Center in North Dakota updated the group on the planned work by the Department of Energy regarding the flammability/ignitability characteristics of these materials.

    Detailed meeting archives are available on the Web site.
