Integrated VES, ERI, and MASW surveys, constrained by boreholes, delineate a central low‐resistivity/low‐V s weak corridor and more competent volcanic strata at depth. The eastern sector offers preferable foundation conditions, while identified weak zones require ground improvement or deep foundations to mitigate differential‐settlement risk.

On the basis of core and log data, a Bayesian‐Optimized Random Forest model achieved 92.76% accuracy in classifying tight sandstone reservoirs. A gray relational analysis‐derived evaluation index shows > 80% consistency with actual gas zones. ABSTRACT Tight sandstone gas (TSG), an unconventional oil–gas resource, has heterogeneous reservoirs ...

Elastic-Wavefield Seismic Stratigraphy: A New Seismic Imaging Technology [PDF]
We have developed a numerical technique that will adjust 3-D S-wave seismic images so that they are depth equivalent to 3-D P-wave seismic images. The ability to make this type of P-SV to P-P depth registration is critical to our elastic wavefield seismic stratigraphy research because we now have higher confidence that depth-equivalent data windows are

Constraints on the evolution of Taranaki Fault from thermochronology and basin analysis: Implications for the Taranaki Fault play [PDF]
Taranaki Fault is the major structure defining the eastern margin of Taranaki Basin and marks the juxtaposition of basement with the Late Cretaceous-Paleogene succession in the basin.

In this work we propose a novel algorithm for multiple-event localization for Hydraulic Fracture Monitoring (HFM) through the exploitation of the sparsity of the observed seismic signal when represented in a basis consisting of space time propagators. We

Hunga‐Tonga Volcano Plumbing System Inferred From Virtual Seismometer Approach
Abstract We present a surface wave tomography application based on event‐pair interferometry to investigate local (∼100 km) mid‐ocean crustal structures, with a particular focus on imaging a potential crustal solidified intrusive complex in a region lacking seismic stations.

Flux and Isotopic Composition of Sedimentary Carbon Subducting Along the World's Trenches
Abstract Here we provide comprehensive estimates for the subducted sedimentary flux of inorganic and organic carbon and δ13C at 16 trench segments worldwide. Our calculations provide minimum (incoming sediment), maximum (trench fill) and best estimates (underthrust) of carbon fluxes.

SRT-Ai: Identifying seismic reflection terminations using deep learning
Seismic stratigraphy entails a regional scanning (reconnaissance) of seismic data to identify and annotate seismic reflection terminations. To identify these terminations in modern 3D seismic datasets, interpreters have to examine thousands of inlines ...

Abstract Subsea permafrost is widespread across the polar continental shelf, and mapping its distribution is crucial for assessing the possible impact of its degradation in response to global warming. While seismic techniques have been useful in determining the lateral extent of subsea permafrost in the Canadian Beaufort Sea, are limited when it comes ...
