About Us

Magnetic Variation Services LLC was founded in 2010 by Stefan Maus to provide services to the oil and gas industry that enhance the accuracy of wellbore placement in directional drilling. In 2014, we added Surcon Ltd as a fully-owned subsidiary, to provide real-time services. Together, the two companies provide the full range of survey management services, including well planning, In-Field Referencing (IFR1)Disturbance Field Monitoring (IFR2), Multi-Station Analysis (MSA), SAG and other advanced techniques.
