Evaluating Fragmentation Detection in Block Caves Using Synthetic Muon Tomography

Geophysical Prospecting, Volume 74, Issue 7, September 2026.
ABSTRACT Muon tomography is a geophysical imaging technique with growing application across a range of geological and industrial settings. By observing the arrival of naturally occurring muons, it is possible to reconstruct subsurface density distributions in three dimensions.

Finite Element Modeling of Spontaneous Potential Well Logs in Complex Near-Wellbore Environments

Geosciences
Spontaneous potential (SP) logging remains a widely used method in well geophysics. However, its interpretation is often limited by simplified physical models and correction charts that do not fully account for the processes governing SP generation ...

Scientific results from the deepened Lopra-1 borehole, Faroe Islands: Wire-line log-based stratigraphy of flood basalts from the Lopra-1/1A well, Faroe Islands [PDF]

Geological Survey of Denmark and Greenland Bulletin, 2006
The present study shows that it is possible to use conventional borehole logs to perform a detailed lithological/stratigraphical division of a column of subaerially extruded basalt.

Performance of Spanish white Macael marble exposed to narrow- and medium-range temperature cycling

Materiales de Construccion, 2010
White marble specimens from Macael in the Spanish province of Almeria were exposed to narrow- (50/20 ºC) and medium- (100/-20 ºC and 75/-20 ºC) range thermal stress cycles. The effects were monitored with ultrasound techniques.

Bayesian NMR petrophysical characterization

Journal of Magnetic Resonance
Identification of reservoir rock types is necessary for the exploration and recovery of oil and gas. It involves determining the petrophysical properties of rocks such as porosity and permeability which play a significant role in developing reservoir models, estimating the volumes of oil and gas reserves, and planning production methods.

Fluid Pathways and Sources Driving Recurring Pockmark Formation on the Chatham Rise, New Zealand

Basin Research, Volume 38, Issue 5, September‐October 2026.
Quasi‐3D seismic data interpretation and spatial pattern analysis indicate that pockmark formation on the SW Chatham Rise is likely driven by a combination of compaction‐related dewatering during polygonal faulting and silica diagenesis, coupled with deeply‐sourced, possibly CO2‐rich fluids from subducted limestones migrating along prominent basement ...

Automated Petrophysics For Real-Time Geosteering

Petrophysics plays a critical role in geosteering by providing insights into reservoir quality-porosity, permeability, saturation, and shaliness. While geosteering traditionally relies on azimuthal and deep-sensing LWD tools to guide wellbore placement ...

Detecting breakpoints in artificially modified- and real-life time series using three state-of-the-art methods

Open Geosciences, 2016
Time series often contain breakpoints of different origin, i.e. breakpoints, caused by (i) shifts in trend, (ii) other changes in trend and/or, (iii) changes in variance.

Geophysical update of the diameter of the Zhamanshin impact structure, Kazakhstan

Meteoritics &Planetary Science, Volume 61, Issue 9, Page 2284-2302, September 2026.
Abstract The rim of the 0.9‐Ma‐old Zhamanshin impact crater in Kazakhstan is considered to be almost completely exposed via a series of hills surrounding a central flat area, indicating an apparent diameter of 14 km. This would make Zhamanshin the second largest impact crater of the Quaternary period. However, the overall geometry of these hills is not
