Dipmeter and borehole image evaluations revolutionized subsurface characterization from the earliest devices invented to delineate bed attitude 90 years ago. Progressive technological advancements now permit detailed studies concerning sedimentology and stratigraphy, structure, and geomechanics in downhole settings probed by traditional O&G exploration and development, carbon capture, utilization, and storage (CCUS), geothermal energy, mining, waste containment, and engineering programs.
Despite the utility of borehole image evaluations, nearly 25 years have passed since analysts gathered in a dedicated session to explore developments in tool technologies, quality-control methodologies, and subsurface applications with the purpose of documenting and consolidating the current state of knowledge. Likewise, few discussions have focused on adopting borehole images in logging programs outside of traditional markets.
The meeting aims to use oral, poster and keynote presentations to do the following:
- Promote collaboration by assembling a multi-disciplinary group of subject matter experts, geologists, geophysicists, petrophysicists, and engineers across multiple industries
- Discuss advancements in borehole imaging physics, technologies, quality control, and the increasing role of AI
- Share integrated evaluation techniques in traditional O&G, emerging CCUS, Geothermal, and Engineering projects

A nearly 90-year journey of image logs and could we log one on Mars?
Bernd Ruehlicke, Eriksfiord
President of Eriksfiord, Inc. part of the Eriksfiord group, a geoscience provider with focus on image/sonic log based geological processing and interpretation and geomechanical studies. Bernd contributed to most of the geological applications modules of Recall (Halliburton) during the time at Z&S where he fell in love with image logs back in 1993 and where memory & diskspace was counted in MegaBytes and CPU power in Mega Hertz. At PGS and Landmark, he worked on the interface between the Petrobank (Oracle) database and Recall, and worked as DevLead on R&D projects such as the Java DecisionSpace platform.
He has published papers on the use of Eigenvectors and symmetry axes in geological interpretations of image logs. He is the author of Vinland, a geomechanical analysis tool based primarily on image logs.
Bernd holds a BS in Computer Science and MS in Mathematics from Aarhus University, Denmark. He has an MBA from the University of Houston-Victoria.
Bernd has previously served as President of the SPWLA Houston Chapter 2022-24. SPWLA Distinguished speaker for 2021-22.
Use and interpretation of borehole image logs in geothermal systems: geology, alteration, structures, borehole conditions, and stress
Nicholas C. Davatzes, Temple University
Nicholas C. Davatzes is Associate Professor and Chair of Earth and Environmental Science at Temple University in Philadelphia, Pennsylvania. A structural geologist and geomechanicist, he has spent more than twenty years acquiring, field-testing, and analyzing acoustic (BHTV) and resistivity (FMI/FMS) borehole image logs to characterize fractures, alteration, and in-situ stress for geothermal exploration, resource management, and enhanced geothermal system development in granite at Coso California, tuffs and meta-sediments across Nevada’s Great Basin, arc volcanics of the Cascades, and basaltic rift systems of Iceland. Across these settings, he integrates borehole imaging with core, field mapping, seismicity, and geomechanical modeling to connect borehole observations to reservoir-scale behavior. He teaches undergraduate and graduate courses in structural geology, natural hazards, and borehole geophysics, and taught geothermal logging as a visiting professor at the RES School of Renewable Energy Science in Iceland. He earned his Ph.D. at Stanford University and was a United States Geological Survey Mendenhall Postdoctoral Fellow
