Raymond G. Teyssandier Texaco Inc. Houston Ronald Beaty Amoco Production Co. Houston Gas volume calculations with the new orifice meter standard will be more accurate than volumes calculated by previous U.S. or international standards. The greatest impact is likely to be on unprocessed gas. The standard is expected to improve the uncertainty range by 0.1-0.5%. Because of the numerous changes in the document, implementation of all parts will not occur immediately but in a timely manner.
