Biographies of our team

Peter Swinburne

Currently the President & Chief Financial Officer of NoHiddenPay LLC. His primary focus is architecting and implementing software solutions for resistivity & EM modelling, and interpretation. He had 23 years seniority with Schlumberger, firstly as an Embedded Software developer and later as an Architect, Software Metier Manager and Advisor. He has worked in many different domains including Aviation electronics and software, Naval electronics and software, Biomedical software, and Oil Field exploration. He has owned several software related companies in both the UK and the US. Peter holds a master’s degree in Digital System Design from Cranfield Institute of Technology.

James Hemingway

Currently the NoHiddenPay LLC Vice President and the Vice President Enhanced Production for NoHiddenPay LLC. He earned degrees in Chemistry and Chemical Engineering. He joined Schlumberger in 1979 and has held various petrophysical and engineering positions for most of his 37-year career. He has been heavily involved in evaluating unconventional reservoirs using electromagnetic and nuclear measurements. He worked on various Enhanced Oil Recovery projects starting in California for 8 years where he developed techniques for reservoir evaluation using high frequency electromagnetic propagation as well cased hole techniques primarily based on pulsed neutron measurements. While working in Paris a few years later he launched an initiative to be called Formation Evaluation Behind Casing (CHFE) with added measurements that did not need to be combined with open hole measurements for completion design. His primary objective for the past 25 years has been to develop viable techniques for formation evaluation behind casing. In 2010 James received the best paper award from the SPWLA for work on a cased hole density measurement. One of the last projects James worked on was the fast neutron cross section as an alternative to using bulk density in cased hole. James was a Distinguished Lecturer for the Society of Petrophysicists and Well Log Analysts in 2000-2001 and 2011-2012 on cased hole logging technologies, and a distinguished Lecturer for the SPE in 2014-2015. James served as President of the Society of Petrophysicists and Well Log Analysts (SPWLA) for the 2020-2021 term.

Eric Decoster

Currently the Vice President South American Basins for NoHiddenPay LLC. He is an engineering graduate from the Ecole Centrale de Paris, with a Master of Engineering from the University of Wisconsin, specializing in flow through porous media. His career with Schlumberger Wireline spans 34 years, beginning as a Field Engineer in the Middle East. Over 34 years, he has occupied various positions in marketing and interpretation throughout the Middle East and Latin America. Early on, he was assigned as Principal Petro Physicist to Venezuela, focusing primarily on the development of interpretation techniques and new technology, including Nuclear Magnetic Resonance and Nuclear Spectroscopy. It is there that he carried out the initial field test of the Dielectric Scanner prototype. In his past position as Schlumberger ́s Petrophysics Advisor for Latin America, he continued to look after Dielectric Scanner interpretation development. Eric has published several papers on Dielectric Scanner applications to Reservoir Characterization. He also served as Latin American director of the SPWLA. Eric is now retired and attempts to remain current with new developments in electromagnetic logging.

Gary Hazen

Currently the Vice President Electrical Systems Engineering for NoHiddenPay LLC. He had a disguinished career with Schlumberger spanning nearly 40 years with expertise in Downhole Electronics, analog design, filter design and systems engineering. He was an electrical Architect for wirelines tools and an expert in receiver and transmitter design for logging-while-drilling Resistivity tools. He also served as the Systems Engineering Metier Manager.

Alan Sibbit

Currently Vice President Interpretation for NoHiddenPay LLC. He retired from Schlumberger in 2016 after a career spanning 41 years. He was a Senior Research Advisor and Technical Director before retiring. Since 2017 he has been a Director and Senior Consultant for Formation Evaluation Technologies working around the globe for the oil and gas industry.

Martin G. Lüling

Martin G. Lüling is currently the Director of Research and Prototyping for NoHiddenPay LLC. He is a physicist, inventor and writer. He obtained his Ph.D. in Princeton University with a study in theoretical elementary-particle physics. He spent a thirty-five year career with Schlumberger Oilfield Services, working on the development of measurement devices and methods as well as data-reduction and processing techniques for oil and gas exploration. Since 2021 he operates his company LulingTech offering services in scientific communication, scientific consulting and scientific creations on environmental questions and natural resources. His work has received 39 patent grants and more publications. For the company NoHiddenPay, he develops new measurement concepts and mathematical algorithms to the level of minimally viable prototypes.

Barbara Anderson

Currently an Advisor for NoHiddenPay LLC. She works remotely from “ohm sweet ohm”. Joining Schlumberger Doll Research in 1966 and she retired in 2007. Since retiring, she worked as a part time consultant for Schlumberger from 2007 to 2013 and has written articles for SPWLA. Today Barbara is a member of SPWLA, SPE and SEG. She has a PhD from Delft University. She served as SPWLA President in 1994-95 and was recipient of the 2002 SPE Formation Evaluation Award and the 2007 SPWLA Gold Medal for Technical Achievement. Her ongoing goal has been to minimize uncertainty in formation evaluation by integrating resistivity tool modeling directly into the interpretation process. She has co-authored several papers that have won SPWLA Symposium and Petrophysics Best Paper Awards, and attributes her success to collaborations with talented colleagues.

Raghu Ramamoorthy

Currently an Advisor for NoHiddenPay LLC. He retired from Schlumberger in 2017 after a career of 35 years. He was a Petrophysics Advisor for the entire spectrum of Reservoir Characterization and an advocate for introducing new technology. He is well published in industry forums such as SPWLA, SPE and AAPG and holds several patents in log interpretation and measurements. He has interpreted log data from most hydrocarbon reservoirs in the Middle East, South-East Asia and Australia. Several interpretation algorithms developed by him are implemented in Schlumberger’s Techlog Interpretation platform. He has served on the board of the International SPWLA. He is a recipient of the Henri Doll and Conrad Schlumberger Awards at Schlumberger Reservoir Symposia and the Regional SPE Formation Evaluation Award for the Middle East. Since 2017 he has been an independent Consultant for Petrophysical issues connected to Logs, Cores, and Tests.
