For 32 years as head of the Geophysics Department of DMT. He nurtured the growth of the organization from a research group of the German coal mining and to Germany’s most important private geophysical contractor. During that time he was responsible for more than hundred research projects for international public and commercial agencies, and for the Mining and Oil/gas- industry. He contributed significantly to the development of 3D-seismic methods from 1975 onward. He holds patents on seismic instrumentation and on specific logging instruments. His emphasis has been to integrate geophysical techniques into mining and borehole applications.
Horst holds a Ph.D. from the Ruhr-University in Bochum, where he is now a part time professor. He is member of many professional societies and on several editorial boards and professional steering groups. Presently, he serves as President of the German Geophysical Society (DGG) and Vice- President of the Geothermal Society (GTV). Horst is widely published and wrote a textbook in in-seam seismics. He received in 2001 the Special Commendation award for taking geophysics beyond its boundaries.
Horst’s present interests are passive seismic monitoring and special logging tool developments. He is known for integrating various disciplines including advanced logging techniques for numerous applications as demonstrated in several international multi-disciplinary projects.
Dr. Charles Stoyer
Dr. Charles H. Stoyer is President of Interpex Limited. He received his Ph. D. in Geophysics from Penn State in 1974. His thesis entailed the first finite difference modeling of 3-dimensional electromagnetic fields in the presence of 2-D earth structures. It also included the design and construction of field equipment for frequency domain electromagnetic data acquisition and a field study in an area known for mine acid drainage.
He was a postdoctoral fellow at CIRES in Boulder, CO working with James R. Wait from 1974-75. By this time, he had authored or co-authored eight papers in peer reviewed journals. From 1975-77 he was a professor of Physics/Geology at New Mexico State University in Las Cruces, NM and he joined the geophysics faculty at the Colorado School of Mines in 1977 where he stayed until 1985. At Mines, he developed several graduate-level courses; one in inversion theory and another in numerical modeling methods. He also implemented a graduate-level laboratory course which was designed by the department as a required core course but which faltered in the hands of older professors. On the research side, he became heavily involved in TEM studies, using controlled sources with powers of tens to hundreds of kilowatts. He implemented a computerized data acquisition system in the late 1970’s and redesigned and constructed both the controlled source and the receiver electronic systems.
Charles co-founded Integrated GeoSciences, Inc. in 1982 and co-founded Interpex Limited in 1986, where he remains today IGS was a TEM contractor in the days when "Frontier exploration areas" were popular and oil prices were predicted to soar. Interpex Limited is a software company catering mostly to the "Near-Surface" contingent of geophysics, and provides off-the-shelf software for modeling, processing and interpreting data taken with Resistivity, Resistivity/IP, frequency electromagnetics, transient electromagnetics (TEM), gravity, magnetics, seismic refraction and seismic reflection. Interpex was never able to identify a software niche in the area of borehole geophysics. Interpex has supplied several thousand software packages to users in academic institutions, government agencies, consultants and major mining and oil companies all over the globe.
Charles received the Alexander von Humboldt Award in 1987 for his work in TEM, and spent approximately 8 months working in Cologne, Germany as a result of this award.
Charles also received the Harold Mooney Award from the Society of Exploration Geophysicists in 2001 for his technical excellence and innovation leading to the advancement of Near-Surface Geophysics
Charles prides himself on algorithm and software development, in particular accuracy and speed with a useable interface and report-ready output.

He was 1998-1999 SPE distinguished lecturer on Through Casing Resistivity. Apart from chairing many workshops at International Conventions he was co-chairman of 3 SEG Summer research workshops on: Integration of Seismic Data with Well Logs (1995), NMR Imaging of Reservoir Attributes (1998), Effective Technology Transfer of Model-based Geo-Inversion Techniques (1999), and Geopressure (2002) . He was also co-chairman of the SPWLA topical conference on Borehole Anisotropy (April 2000) and Guest Editor of the special issues of Petrophysics on Borehole Anisotropy. Kurt has taught courses and mentored many students and professionals at many universities and many companies in the international oil industry.
Kurt received the Distinguished Technical Achievement Award (2003) from the SPWLA for his contribution to innovative logging tool technology. The SEG granted him the Reginald Fessenden Award for his instrumental role in the development of through casing resistivity and 3D induction. The Russian Academy of Science elected him a Foreign Member and gave him the Kapitsa Gold Medal of Honor in recognition for his innovative contribution to borehole geophysics and pioneering work to surface geophysics.

Seismic polar anisotropy (His 1986 paper establishing key concepts is the most-frequently cited paper in the history of Geophysics.)
Seismic azimuthal anisotropy (He discovered the phenomenon in 1980; his 2006 paper establishes that the P-wave seismic signature corresponds to real subsurface fracture patterns.)
Converted-wave seismic (His 1999 paper established numerous key concepts, such as C-waves, γeff, diodic velocity, vector fidelity, vector reciprocity, and event registration.)
Electromagnetic imaging, seismic style (with KMS personnel)
