Walter Seidl
Mr. Seidl joined the CEESI staff in 1970 and retired in 2010.
His experience includes instrumentation engineering, flow system design, test program design, and analysis of engineering data.
He has authored numerous papers on flow measurement and taught classes at the International School of Hydrocarbon Measurement in Oklahoma.
Seidl is involved in national and international flow standards activities and is chairman of the Critical Flow Committee of the ASME MFFCC standards group.
Charlie Britton Engineering Resume
Mr. Charlie Britton earned his BS in Mechanical Engineering in 1965 from the University of Colorado at Boulder.
He worked as a research engineer for the University after graduation and became the first lab manager of the Experimental Station when it moved from the University to its present location in Nunn, Colorado.
Mr. Britton has been instrumental in the development of CEESI’s calibration and test stands.
He left CEESI in 1975 to begin an independent consulting business and later worked for Dieterich Standard where he became the Vice President of Engineering.
Mr. Britton brings to CEESI over 33 years of experience in design and construction of high pressure gas flow test facilities, design of experimental techniques for flow meter evaluation and development of computer data acquisition/reducing programs.
Stephen T. (Steve) Stark
Stephen T. (Steve) Stark serves as an independent staff advisor and consultant to CEESI.
Through his company,
Stark & Associates, Inc., Steve provides independent measurement consulting and services to gas and energy industry organizations throughout the world.
Before forming
Stark & Associates, Inc. in 1997, he held management, engineering, technical, and operational positions with organizations including The Williams Companies in Tulsa and Phillips Petroleum Company in Bartlesville.
Steve has served on numerous energy industry committees, includes those of the American Petroleum Institute (API), American Gas Association (AGA), and Gas Processors Association (GPA).
He has actively participated in the writing of more than a dozen gas and liquid measurement standards and has chaired activities of the Southern Gas Association (SGA), GPA, Gas Research Institute, Midwest Measurement Society, and others.
He has also served on the Board of Trustees, Executive Committee, and General Committee of the International School of Hydrocarbon Measurement (ISHM).
He was ISHM's General Chairman in 1996, founding the ISHM/University of Oklahoma Scholarship Fund that same year.
Steve's professional accomplishments include four U.S. patents, all relating to the science of fluid measurement, and the writing of numerous technical papers, reports, and articles on the subject of natural gas and liquid measurement.
Dr. Jeff Savidge Engineering Resume
Dr. Jeffrey L. Savidge received his Bachelors Degree in Chemistry from Oklahoma University in 1977, his Masters in Chemical Engineering from the University of Oklahoma in 1984 and his Doctorate in Chemical Engineering from the University of Oklahoma in 1986.
Dr. Savidge has over twenty years of technical and management experience in the development of high accuracy natural gas and related fluids measurement and related engineering models.
He has completed extensive fluid composition and thermo-physical property data analysis for high accuracy metering and gas custody transfer applications.
He has developed and led high accuracy equation of state development and programming efforts for AGA, API, ISO and GPA, industry standards used to compute natural gas and relate compressibility, density, sound speed, heat capacities, critical flow factors, enthalpies and entropies.
Dr. Savidge has provided significant advances in basic and applied research for natural gas measurement, gas dehydration, gas hydrates and acid gas treating.
He has conceived a number of patents for improved gas measurement.
He is also responsible for the technical development of US and ISO standards in high accuracy gas measurement for large scale natural gas custody transfer.
He has developed and managed GRI's Basic Research Program in the Fluid Properties of Natural Gas and Related Fluids from 1987 to 2000.
