Reconstructing the Distribution of Turbiditic Gas Sandstones in the SW Pannonian Basin Using Machine Learning Methods

Geophysical Prospecting, Volume 74, Issue 2, February 2026.
ABSTRACT Seismic interpretation in geologically complex environments still remains a challenge due to limited resolution and ambiguous facies differentiation. In this article the 3D seismic data from the Gola field, south‐western Pannonian Basin, were interpreted using unsupervised self‐organizing maps (SOM) on unlabelled data.

Precise Characterization of Fluid Logging Responses in Complex Shale Reservoirs: A Case Study From the Hongxing Area, Eastern Sichuan Basin

Geofluids, Volume 2026, Issue 1, 2026.
Precise characterization of fluid‐sensitive logging responses in complex shale reservoirs is very important. It is essential for quantitative formation evaluation and development optimization. Based on a case study of the shale gas reservoir in the second member of the Wujiaping formation (hereinafter referred to as the Wu‐2 Member) in the Hongxing ...

Controls of Base‐Level Cycles on the Sedimentary Architecture of Subaqueous Distributary Channels in a Lacustrine Delta: A Case Study From the Chang 8 Member, Ordos Basin

Geofluids, Volume 2026, Issue 1, 2026.
Base‐level cycles serve as a crucial reference for the stratigraphic sedimentology. In lacustrine basins, high‐frequency base‐level changes contribute to significant diversity and complexity in sequences and sedimentary infilling. The sequences′ infill and facies distribution in lacustrine basins differ greatly from marine deposits.

A Novel Intelligent Sedimentary Microfacies Identification Model Based on Limited Well‐Logging Data

International Journal of Intelligent Systems, Volume 2026, Issue 1, 2026.
Sedimentary microfacies identification is fundamental for reservoir characterization, directly influencing hydrocarbon exploration and production strategies. However, traditional methods relying on core analysis, seismic interpretation, and manual well‐log analysis face significant challenges: (1) high costs and limited coverage of coring data, (2 ...

A >70‐Myr‐Long Geomagnetic Field Reversal Hyperactivity Across the Ediacaran‐Cambrian Transition

Geophysical Research Letters, Volume 52, Issue 23, 16 December 2025.
Abstract The long‐term variation of the geomagnetic field is a key constraint for unraveling the geodynamo processes and the evolution of Earth's deep interior. However, the geomagnetic reversal pattern during the Ediacaran–Cambrian transition remains elusive. Here we present an integrated magneto‐ and cyclo‐stratigraphic study of a ∼1.8‐Myr‐long, late
