Workshop Goals

GEM Beijing 2011 was a successful workshop that attracted participants from different countries and provided excellent networking opportunities for geophysicists from different continents. The goal of GEM Chengdu 2015 is again to bring together experts from academia, government agencies, resources companies, and contractors to share the latest technological and methodological developments and successful experiences, and to discuss challenges and future directions and needs. Gravity, electrical, electromagnetic, magnetic, and nuclear magnetic resonance methods are among the primary tools for exploring natural resources (oil and gas, minerals, geothermal) as well as for tackling geotechnical and environmental problems. Sensors, tools, acquisition techniques, processing and interpretation methods are common among these different applications. This Workshop covers the technologies and methodologies, brings a suite of applications to a common forum, so that we can enjoy and learn from related applications of the same technologies.
