About Us

Magnetic Variation Services LLC was founded in 2010 by Stefan Maus to provide geomagnetic field services to the oil and gas industry. We specialize in the processing of airborne, marine, ground and downhole magnetic field measurements to produce accurate In-Field Referencing (IFR) models and software for directional drilling.

Stefan Maus, Director

Stefan Maus is a Senior Scientist at the University of Colorado and leads the Geomagnetism Team at NOAA’s National Geophysical Data Center, which produces global geomagnetic field models, such as the World Magnetic Model and the High Definition Geomagnetic Model. He received a BSc in Mathematics in 1988 and a MSc in Geophysics in 1993, both from the University of Munich (Germany), followed by a PhD in 1997 at National Geophysical Research Institute in Hyderabad (India). After a Post-doc in Leeds, he taught Geophysics at the University of Braunschweig and at Free University Berlin. From 2000-2004 he was the specialist for crustal magnetic fields in the CHAMP satellite team at GeoForschungsZentrum Potsdam. Stefan continues to be involved in magnetic satellite missions, in particular as member of the Mission Advisory Group and the Validation Team of the Swarm satellite mission of the European Space Agency. His primary interest lies in Geomagnetism, with a focus on producing magnetic field models for research and navigation from satellite, airborne and marine magnetic measurements. Stefan has authored and co-authored more than 100 peer-reviewed publications. In 2010, he founded Magnetic Variation Services LLC to provide specialized geomagnetic field services to the oil and gas industry.

Ryan Paynter, Geophysicist

Ryan Paynter graduated from Colorado School of Mines Golden, Colorado in 2009 with a major in Geophysical Engineering and minors in Geology and Economics. He has been with Magnetic Variation Services since 2011 and specializes on magnetic data processing, map production and GIS. Enjoys the challenge of applying gravity and magnetic potential fields to solving real world and theoretical problems. Also enjoys life outside the office spending time with friends and family, mountain biking, road biking, hiking, photography and the occasional pick-up soccer game with friends.

Rahul Chirumamilla, Software Engineer

Rahul Chirumamilla graduated from Montana State University, Bozeman Montana with a bachelor's degree in Computer Science. He joined Magnetic Variation Services in early 2012. Rahul develops the MagVAR Calculator, which is one of our core products. He enjoys designing innovative user interfaces and likes the challenge of solving problems with latest technology stack. Interested in object oriented programing paradigms, especially Java. Besides coding he enjoys outdoors, snowboarding, badminton, hiking and spending time with family and friends.

Matthew Herzl, Software Engineer

Matthew Herzl graduated from CU in 2009 with a double major in Mathematics and Physics. He joined Magnetic Variation Services in May 2013 to develop algorithms for well trajectory computation and MWD instrument performance analysis. He enjoys how developing software to model aspects of the drilling process involves a combination of interests including physics, mathematics, and software engineering. In addition to his work at MagVAR he also enjoys reading books, time with friends, and running and other outdoor activities.

William Daniels, Software Engineer

William Daniels is currently a senior, finishing up his degree at the University of Colorado, Denver, majoring in Computer Science with a minor in Mathematics. He joined Magnetic Variation Services in October of 2013. William works on the MagVar calculator, as well as integrating and streamlining automated build systems. He enjoys finding new ways to improve on existing processes throughout the company, as well as taking on the everyday challenges that working with the latest technologies provides him with. In his spare time will enjoys offroading, hiking, reading sci-fi novels, or a good game of pool.
