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.

  • Interest in WTI/Domestic Sweet Quality

    by Dennis Sutton | Apr 19, 2015
    As the production of North American light, tight oils continues to grow, there has been a great deal of discussion regarding the quality of WTI.  Inquiries regarding WTI have primarily pertained to asphaltene precipitation and the increasing API gravity of the stream. 

    Currently, the NYMEX specs for WTI are a maximum API of 42.0, while the Bridge Tex Pipeline system has a published spec of 36-44 API for WTI.

    In an effort to better define WTI, in addition to the specs set forth by NYMEX, in 2010,  the COQA recommended specs for:
         • MicroCarbon Residue (MCR)
         • Total Acid Number (TAN)
         • Nickel Content
         • Vanadium Content
         • Three boiling range parameters based on High Temperature Simulated Distillation

    For an update on WTI quality, check out the February 2015 COQA presentation by Dennis Sutton.

  • Light, Tight Oil Discussion and Baker Hughes Tour Highlight Houston COQA Meeting

    by Dennis Sutton | Feb 23, 2015

    Amidst the backdrop of two recent crude-by-rail incidents (one in the US and one in Canada), low crude oil prices, and a nationwide United Steelworker strike at US refineries, the COQA meeting February 19 at the Marriott West Loop in Houston attracted 136 attendees.  A number of the presentations addressed quality aspects related to light, tight oil.  Talks by Kesavalu Bagawandoss, Intertek and Jason Nick of Ametek specifically dealt with vapor pressure measurement. 

    David Lord of Sandia National Laboratories provided an update on the planned work of the Department of Energy’s project on “Tight Oil Flammability & Transportation Spill Safety”. To date, a literature survey has been completed.  The COQA will look forward to future reports on this project as experimental work is conducted.

    In his talk “Crude Oil Quality Management in a Volatile Crude Price Marketplace”, Baker Hughes’ Waynn Morgan helped us to recall that crude prices historically have been quite volatile, with a price around $10/bbl in 1998, followed by $130/bbl just 10 years later.  The price was about $100/bbl in mid-2014, before the collapse to the current levels of about half of that.     

    In addition to event sponsorship from Ametek and Analytical Systems KECO, Baker Hughes provided an outstanding tour of their Woodlands Technology Center, where they manufacture drill bits used throughout the world.  This tour was given on Wednesday morning, February 18, and was open to all meeting attendees.  While the COQA is focused on the crude oil, it was fascinating to learn of the history of drill bit technology, and see the sophisticated robotic manufacturing techniques used to produce today’s drill bits.                                            COQA_BakerHughes 1_1


  • COQA Partners for the Argus Americas Crude Summit

    by Dennis Sutton | Feb 05, 2015

    The Argus Americas Crude Summit, held January 27-29 in Houston, drew a record crowd of over 450 attendees.  The Crude Oil Quality Association (COQA), once again served as a Partnering Organization for this significant conference.  Speakers at the conference included Matthew Goitia of Peaker Energy Group and Ashok Anand of Enbridge Pipelines, both of whom are also part of the program for the February 19, 2015 COQA meeting in Houston.

    Besides the presentations, there were approximately 16 exhibitors.  Five of the exhibiting companies represented are members of the COQA.  These are:

    • Amspec
    • Baker Hughes
    • Inspectorate
    • Intertek, and
    • Spiral Software/ Schneider Electric.

    The conference began with three keynote talks from the Honorable Newt Gingrich, former Speaker of the House; Joe Gorder, Chairman, President and CEO of Valero Energy; and Harold Hamm, Chairman and CEO of Continental Resources. Mr. Gingrich spoke on the geopolitical aspects of the current crude oil price decline expressing that he was “glad” the oil prices were giving Putin a headache as the Russians could withstand a lot of economic pain before it undermined them.

    Overall, the pervasive theme through the program was how to move forward amidst the economic chaos associated with the crude price collapse.
  • Joint COQA/CCQTA Meeting Draws 125 to San Francisco

    by Dennis Sutton | Oct 30, 2014
    The recently concluded joint COQA/CCQTA international meetings in San Francisco, October 30 & 31 drew over 125 attendees from throughout North America!

    The two day conference featured general industry overviews highlighting the on-going changes brought about by the growth in shale play crude, as well as more technical presentations.  After introductory discussions by Dennis Sutton (COQA), and Gerald Bruce (CCQTA) about their respective organizations, Martin Tallett kicked off the program with a presentation on "North American Crude Supply and Logistics".  The Thursday afternoon session focused on light, tight oil and crude-by-rail, and included an update on API's Recommended Practice 3000 (RP3000). 

    Friday morning shifted to activities North of the Border as the Canadian Crude Quality Technical Association (CCQTA) addressed their many on-going industry projects, including recent work with detailed chromatographic analyses on the light oils.

    Friday afternoon featured an overview of current refining challenges provided by Jim Johnson of Marathon Petroleum, the US's 3rd largest refiner.  Three talks addressed specific analytical applications, with Scott Sederberg of Chevron concluding the conference by looking at historical game changers in crude oil production.
