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. 

SGS is a member of the COQA, with SGS crude oil quality and assay experts participating in the COQA. 

SGS will be presenting at the June 2017 meeting in St. Louis. Arden Strycker Ph.D., SGS, is giving the COQA an update on “GC Merge of Light ends with ASTM D7169 Boiling Point Distribution,” to provide the audience an update on his latest observations regarding the procedures, benefits, and limitations of merging ASTM D7169 with ASTM D7900 when building crude oil assays.
