Microscopic Pore–Throat Architecture and Fractal Heterogeneity in Tight Sandstone Reservoirs: Insights from the Denglouku Formation, Xujiaweizi Fault Depression

Applied Sciences
The heterogeneity of the microscopic pore structure in tight sandstone reservoirs is a key factor limiting the efficient development of natural gas. This study focuses on the tight sandstone of the Denglouku Formation in the Lower Cretaceous region of ...

Logging evaluation method of fracturability of tight sandstone reservoirs

Youqi dizhi yu caishoulu
The fracturability of reservoirs is an essential parameter for selecting perforation stages and predicting hydraulic fracturing effects， but fracturability evaluation for tight sandstone reservoirs lacks unified methods and standards. This paper studies Chang 6 tight sandstone reservoir in an oilfield in the southeastern part of Ordos Basin and ...

Ground Penetrating Radar Observations of Subsurface Structures From the Makgadikgadi Pans (Botswana): A Terrestrial Analogue of Martian Playa Lakes

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract Playa lakes are considered promising landing sites on Mars because of their strong astrobiological potential. Therefore, sediments and buried structures in terrestrial playa lakes have become the focus of numerous analogue studies. The inclusion of ground penetrating radar (GPR) in the payloads of Martian missions has opened new avenues for ...

Subsurface Hydrocarbon Biodegradation in the Context of Microbial Habitability and Hydrogeologic, Thermal, and Geologic Evolution of the Colorado Plateau

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 10, October 2026.
Abstract Subsurface microbial ecosystems associated with hydrocarbon reservoirs are shaped by temperature, salinity, redox gradients, and fluid flow. However, the drivers of microbial activity and hydrocarbon biodegradation over geologic timescales remain poorly constrained.

A New Experimental Design to Measure Second‐ and Third‐Order Anisotropic Rock‐Stiffness Coefficients Using a Single‐Rock Sample

Geophysical Prospecting, Volume 74, Issue 8, October 2026.
ABSTRACT We developed a new experimental setup for measuring and modelling stress‐induced anisotropy and nonlinearity in cylindrical rock samples. Multidirectional ultrasonic velocity measurements were conducted under laboratory conditions and during triaxial‐stress testing to capture dynamic rock properties. This is done by placing endcap transducers (

Mining Impacts on a Threatened and Burnt Swamp Ecosystem: Responses of the Microbial Soil Community

Environmental Microbiology Reports, Volume 18, Issue 5, October 2026.
The evaluation of microbial communities and soil chemistry of three mined and three unmined swamps in the burnt southeastern Australia suggested that mining activities led to changes in the microbial community structure and functionality. This figure incorporates symbols sourced from BioRender and was created with BioRender.com.

Scientists’ warning on the global destruction of rock outcrop ecosystems

Conservation Biology, Volume 40, Issue 5, October 2026.
Abstract Rock outcrops are geological formations that harbor a highly specialized biota adapted to harsh environmental conditions that differ from their surrounding landscapes. They are globally distributed, especially in old, highly weathered landscapes, and can function as habitat islands containing high levels of endemism and distinct evolutionary ...

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 ...

Outcrop and subsurface characterisation of a mixed tidal and wave‐influenced coastline (Triassic Red Beds, SE Spain)

Sedimentology, Volume 73, Issue 6, Page 2381-2416, October 2026.
ABSTRACT Paralic depositional systems are complex and heterogeneous sedimentary environments, presenting challenges for predicting reservoir architecture and connectivity. Their stratigraphic and facies variability arises from the dynamic interplay between fluvial, tidal and wave processes, and their sensitivity to sea‐level fluctuations, sediment ...

A Triassic chronostratigraphic and palaeogeographic framework for the Utsira High area, northern North Sea: Reconstructing a basin‐scale drainage divide

Sedimentology, Volume 73, Issue 6, Page 2417-2453, October 2026.
ABSTRACT The Triassic succession of the northern North Sea comprises a series of interbedded sandstones, mudstones and conglomerates deposited under a fluctuating arid to semi‐humid climate regime, which are often difficult to correlate regionally due to differing lithostratigraphic schemes and poor age control. Despite existing regional studies on the
