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

Terra Nova, EarlyView.
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 ...

Tight Sandstone Gas Reservoir Types and Formation Mechanisms in the Second Member of the Xujiahe Formation in the Anyue Area, Sichuan Basin

Energies
With the advancement of oil and gas exploration and development, tight sandstone gas has become a major current exploration field. However, the effective development of tight sandstone gas faces significant challenges due to the strong heterogeneity of ...

Pore structure characterization and its influence on aqueous phase trapping damage in tight gas sandstone reservoirs.

PLoS ONE
Aqueous phase trapping (APT), which is one of the most prominent damages, seriously restricts the natural gas production in tight gas sandstone with low permeability.

Tectono‐Stratigraphic Evolution of a Shared Foreland Basin: A 3D Geomodel and Detrital Flux Reconstruction for the Pliocene‐Pleistocene of the Po‐Plain Basin (Northern Italy)

Basin Research, Volume 38, Issue 5, September‐October 2026.
The Plio‐Pleistocene succession of the Po Plain Basin was interpreted basin‐wide using seismic profiles and well data, identifying six major tectonic unconformities. Sediment volumes were calculated and decompacted to assess tectonic and climatic controls on basin infill, revealing a marked increase in detrital flux after 1.5 Ma, coincident with the ...

Comprehensive Analysis for the Evaluation of Torrential Floods and Slope Stability of River Channels: La China River Area (Colombia)

Journal of Flood Risk Management, Volume 19, Issue 3, September 2026.
Colombia and other tropical regions face a very high threat from torrential floods, which have resulted in over 25,000 deaths in a single event. Unfortunately, there is no comprehensive assessment methodology to zone and determine the magnitude of these disasters; therefore, this research aims to help fill this gap.

Time‐dependent (Creep) Compaction in Volcanic Rocks

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Porous volcanic rocks form volcanic edifices and host key geothermal reservoirs worldwide. When subjected to constant stress above dilatancy in the brittle regime, these materials undergo time‐dependent failure known as brittle creep. In the ductile regime, where deformation is compactive, time‐dependent compaction—compaction creep—has been ...

Spatially resolved 23Na magnetic resonance dispersion measurement in porous media

The Canadian Journal of Chemical Engineering, Volume 104, Issue 8, Page 4135-4150, August 2026.
Quantitative 23Na MRI was employed to analyze dispersion in realistic core plug samples and was compared with the conventional breakthrough curve. 23Na MRI provided a more effective aassessment of core plug heterogeneity than the conventional method. Abstract Tracer tests are widely used in the petroleum industry to assess reservoir core plugs, relying

Numerical Simulation of Water‐Rock Reaction for CO2 Sequestration in Sandstone Reservoir

Engineering Reports, Volume 8, Issue 8, August 2026.
Based on the TOUGHREACT software, the spatiotemporal evolution laws of parameters including gas–liquid saturation, mineral composition, ionic composition, temperature and pH during CO2 injection under different injection‐production well spacing conditions were systematically investigated.
