Combined petrophysics and 3D seismic attributes to predict shale reservoirs favourable areas

Journal of Geophysics and Engineering, 2019
To achieve the economic and effective development of shale gas, it is not only necessary to determine favourable geological areas but also to pay more attention to favourable engineering areas.

Systematic Approach for Carbonate and Volcanic Facies Classification Based on Textural and Structural Variations Observed in Brazilian Pre‐Salt Acoustic Image Logs

Journal of Petroleum Geology, EarlyView.
ABSTRACT Facies characterization in carbonate reservoirs remains challenging due to their pronounced textural and structural heterogeneity. Variations in grain packing, cementation, and diagenetic overprints produce contrasting acoustic responses in borehole image logs, often limiting the reproducibility of facies interpretation.

New knowledge about shock events that affected the L‐chondrite parent body from two heavily shocked L6 meteorite finds

Meteoritics &Planetary Science, EarlyView.
Abstract We report new results from a study of shock‐related features in the L6 ordinary chondrites Northwest Africa (NWA) 4672 and NWA 12841. Our observations confirm the occurrence of eight high‐pressure (HP) minerals in each meteorite, namely, ringwoodite, majorite, akimotoite, wadsleyite, albitic jadeite, lingunite, tuite, and xieite.

Digitized Stratigraphic and Geophysical Logs From Deep Boreholes in the 2022 Mw 5.5 Fano‐Pesaro Earthquake Region, Adriatic Sea, Italy

Geoscience Data Journal, Volume 13, Issue 3, July 2026.
Legacy borehole documentation from seven deep exploration wells in the Pesaro–Fano offshore area (Adriatic Sea) was digitized into an accessible dataset of stratigraphic and geophysical data. The dataset is openly available in the Zenodo repository and supports future geological and geophysical studies in the Adriatic region and beyond.

Prediction method of coalbed methane enrichment area based on multi parameter fusion

Meitan kexue jishu
Coalbed methane (CBM) is a kind of gas reservoir which mainly exists in coal reservoirs in adsorption state. The prediction of coalbed methane enrichment area by seismic exploration is an important method to reduce the exploration risk and improve the ...

Widespread Impact‐Induced Crustal Permeability on the Early Earth

AGU Advances, Volume 7, Issue 3, June 2026.
Abstract The early Earth (i.e., Archean and Hadean Eons, 2.5–4.0 and 4.0–4.5 Ga, respectively) experienced frequent cosmic bombardment. Impacts have been shown to stimulate crustal alteration, for instance via hydrothermal systems active for up to millions of years post‐impact.

Using Generative Adversarial Networks to Translate Microresistivity Image Logs of Carbonates Into Synthetic Core Images With Accurate Dunham Textures

Journal of Geophysical Research: Machine Learning and Computation
Core images provide a high‐resolution data set of the textures and fabrics of sedimentary rocks, but their availability is often limited by cost and/or poor core recovery.
