1D Basin Modelling of Upper Jurassic to Upper Cretaceous Source Rocks in the Southern Pletmos Sub‐Basin, Outeniqua Basin, Offshore South Africa

Journal of Petroleum Geology, Volume 49, Issue 4, Page 1382-1411, October 2026.
ABSTRACT The Pletmos sub‐basin in the Outeniqua Basin, offshore South Africa, is divided by the Superior, Pletmos and Plettenberg faults into northern and southern depocentres. In this study, geological and organic geochemical data together with 1D basin modelling were used to investigate the burial, thermal and maturation histories, and the timing of ...

Flow field distribution and overpressure characteristics inside the crew compartment of a truck-mounted howitzer under the effect of muzzle blast

Defence Technology
The muzzle blast overpressure induces disturbances in the flow field inside the crew compartment (FFICC) of a truck-mounted howitzer during the artillery firing.

Porosity Preservation in Deeply Buried (8500 m) Jurassic Calcareous Mudstones of the Vienna Basin (Austria)

Terra Nova, Volume 38, Issue 5, Page 306-313, October 2026.
ABSTRACT Significant porosity of more than 5% was found at depths of more than 8500 m in poorly sorted, calcareous mudstones of the Malmian Mikulov Formation. These overpressured rocks are the main hydrocarbon source rock in the Vienna Basin. Core samples from present‐day depths of 8150 m to 8550 m were analysed using X‐ray diffraction and scanning ...

Reaction‐Gated Transient Permeability in Ductile Shear Zones

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Ductile shear zones act as transient pathways for crustal fluids, yet the conditions under which their connected porosity becomes sufficient to conduct are not well constrained. We present a porosity balance in which connected porosity evolves under three competing processes: creation by creep cavitation, creation by metamorphic reaction, and ...

The Influence of Pore Porosity on Overpressure Formation: A Case Study of Field X, Kutai Basin

JGEET: Journal of Geoscience, Engineering, Environment and Technology
The Kutai Basin is a region with complex geological characteristics, which complicate formation pressure prediction and pose drilling risks such as overpressure. This study aims to analyze the relationship between porosity and overpressure using well log

Aseismic Slip Along the Evaporite‐Rich Strike‐Slip Katouna‐Stamna Fault in Greece

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Aseismic slip has been observed on many active faults globally, but its controlling mechanisms remain unclear. This study focuses on the NW‐striking, left‐lateral Katouna‐Stamna Fault in Western Greece. We use InSAR surface deformation measurements to confirm the presence of aseismic slip and compare this behavior with structural evidence from

Mechanism governing spatiotemporal evolution of confined overpressure induced by PTFE/Al reactive jets

Materials & Design
An interfacial-temperature-based ignition model is developed to describe shock-induced reactions in heterogeneous PTFE/Al composites and embedded into a multi-physics Material Point Method–Shock Induced Chemical Reaction (MPM-SICR) framework.

Significant Reduction in Ethane Emissions in the Denver‐Julesburg Basin From 2015 to 2021 From Oil and Natural Gas Operations

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 17, 16 September 2026.
Abstract Top‐down studies of methane (CH4) emissions often use the average ethane‐to‐methane (C2/C1) ratio of wellhead gas in a basin to attribute emissions to thermogenic or biogenic sources. Biogenic CH4 sources (ruminants, wetlands, landfills, and other methanogenic sources) do not co‐produce ethane (C2H6); the presence of C2H6 indicates a ...

Fluid Injection Triggers Large‐Scale Slow‐Slip Activation of the Rocky Mountain Fold and Thrust Belt

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Using interferometric synthetic aperture radar (InSAR) we show that hydraulic fracturing treatments near the subsurface deformation limit of the Rocky Mountain Fold and Thrust Belt produced 12 intraplate, aseismic, slow‐slip events with magnitudes Mw ${M}_{w}$ 4.71–5.06 at 1,640–2,410 m depths.

3D Subduction Interface Model for the Hikurangi Margin, New Zealand: Implications for Slow Slip Events

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract We present a new 3D Hikurangi subduction interface model by using an implicit modeling approach that integrates seismic‐reflection profiles, relocated hypocenters, focal mechanism orientations, and tomographic interpretations. The model reveals along‐strike transitions in slow slip events (SSEs) that correlate with subduction interface ...
