The original vision for this RECORDER edition’s theme was that we would feature a collection of articles that focused on new, leading edge geophysical technologies in applied use. We fell short of that goal, and that is probably because entirely new geophysical technologies are rare, and most of what is… continue reading.
Muon Geotomography: A Novel, Field-Proven 3D Density Imaging Technique for Mineral Exploration and Resource Monitoring
Muon geotomography is a novel density measurement technique based on the absorption of cosmic ray muons in the ground. Naturally occurring cosmic ray muons emanating from the upper atmosphere lose energy as they penetrate the earth. These muons are absorbed at a rate that is proportional to the density of… continue reading.
Over the past 10 years, land seismic acquisition has changed significantly. Nodal/cable-less systems have broadly replaced cabled systems, vibroseis sources have replaced explosive sources even in areas with difficult terrain, and high-density seismic programs are becoming commonplace. This article, based on the Chief Geophysicists Forum presentation “Top 5 Innovations in… continue reading.
The Schlumberger brothers were the first to use the direct current (DC) resistivity method for exploration in oil well boreholes in Russia during the 1920’s. A unique phenomenon, now referred to as induced polarization (IP) chargeability, was noticed at the time, but not understood until simultaneous developments in both Russia… continue reading.

In the Athabasca oil sands, lithology and fluid composition are typically better correlated with density than with other elastic properties, such as P- or S-wave velocity. Therefore, improving the accuracy of density estimates in oil-sands reservoirs has become one of the most important goals in quantitative interpretation, which integrates seismic,… continue reading.
Sedimentary Geology and Implications for Carbon Sequestration: A Field Course in Ainsa, Spain through Project Carbeor
Adriana Gordon, Scott Keating, and Tyler Spackman
A course organized by the Geoscience Department of NTNU (Norway) took place in mid-June in Aínsa, Spain. Graduate students from NTNU, TUDelft (Netherlands) and the University of Calgary participated. Geological outcrops were used to provide an introduction to deep marine, shallow marine and fluvial sedimentary systems. Implications of these sedimentary… continue reading.
