Seismic mapping of subsurface faults is hampered by factors such as seismic resolution,
velocity control for depth conversion and human bias. Here, we explore the challenges and …

Abstract Evaluation of underground processes requires numerical modeling based on
sophisticated and reliable meshing. Our new GeoMeshPy library focuses on the …

Frictional strength of fault zones is a key parameter for evaluation of fault stability and
reactivation. We measure friction using the direct shear test (DST) for (i) sand-clay mixes …

Carbon capture and storage (CCS) is a critical component of proposed pathways to limit
global warming, though considerable upscaling is required to meet emissions reduction …

Abstract 3D seismic reflection imagery is the most widely used resource for interpreting the
geometric structure of faults in the subsurface. Yet these endeavours carry uncertainties, the …

Extraordinary 3D seismic data from the Central Offshore Platform (Southern North Sea),
complemented by information from 38 boreholes, reveal a 10 km-wide basement fault zone …

This study investigates the limitation of simplified stress path assumptions, particularly
uniaxial strain conditions, in fault stability assessments for CO 2 injection sites. We …

Injection-induced rock mechanical failure risks are critical in CO2 sequestration, and thus
there is a need to evaluate these occurrences to ensure safe and reliable subsurface …

Faults play an essential role at many potential CO2 storage sites because they can act as
conduits or barriers to fluid flow. To contribute to the evaluation of the Aurora storage site in …

Seismic resolution and illumination issues are sources of challenges in the detailed imaging
and detection of subsurface fault architecture and fluid migration. Improved constraints on …
