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. The COQA believes the commonly used industry standards of gravity and sulfur do not adequately define crude oil quality, and should be expanded to include other characteristics. The COQA is opposed to the alteration of crude oil streams, such as through the injection of processed gas liquids, without the knowledge and consent of the parties involved
