Frequency-dependent AVO attribute: theory and example [PDF]

, 2012
Fluid-saturated rocks generally have seismic velocities that depend upon frequency. Exploring this property may help us discriminate different fluids from seismic data. In this paper, we introduce a scheme to calculate a frequency-dependent AVO attribute

Hotspots, trends, and regional focus on oil or gas exploration: A bibliometric comparative study

Deep Underground Science and Engineering, EarlyView.
This paper explores the research trends in global oil and gas exploration through the bibliometric analysis of 3460 articles collected from the Web of Science database on oil and gas exploration published from 2013 to 2023. The research hotspots, objects, regional distribution, methods, and evaluation methods of oil and gas exploration are analyzed and

COVID-19 societal response captured by seismic noise in China and Italy

, 2020
Seismic noise with frequencies above 1 Hz is often called cultural noise and is generally correlated quite well with human activities. Recently, cities in mainland China and Italy imposed lockdown restrictions in response to COVID-19, which gave us an ...

Magneto--Acoustic Energetics Study of the Seismically Active Flare of 15 February 2011

, 2012
Multi--wavelength studies of energetic solar flares with seismic emissions have revealed interesting common features between them. We studied the first GOES X--class flare of the 24th solar cycle, as detected by the Solar Dynamics Observatory (SDO).

Quaternary rupture of a crustal fault beneath Victoria, British Columbia, Canada [PDF]

, 2017
The seismic potential of crustal faults within the forearc of the northern Cascadia subduction zone in British Columbia has remained elusive, despite the recognition of recent seismic activity on nearby fault systems within the Juan de Fuca Strait.

Experimental study on dynamic behavior analysis of coal and its acoustic emission response characteristics under impact failure

Deep Underground Science and Engineering, EarlyView.
Based on acoustic emission response characteristics, it can be more accurate to identify the damage evolution process of coal under the combined dynamic and static loads, reveal the moment corresponding to coal damage, and identify the characteristics of coal failure. The research results are conducive to the further use of acoustic emission monitoring

Machine Learning-Based Prediction of Subsurface Elastic Properties Using Seismic and Well-Log Data

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
The elastic properties of subsurface media, such as density and P- and S-wave velocity, are essential for understanding the mechanical behavior of the subsurface as they reflect its physical and structural characteristics. Accurate elastic properties are

Form and load transfer aspects of foundation systems: Case‐based implementation and adaptation for buildings

Deep Underground Science and Engineering, EarlyView.
Upon conceptualization of structural behavior, foundations in terms of their form are divided into linear (1D), planar (2D), and volumetric (3D). Regarding the load transfer mechanisms, linear foundation systems are considered vector‐acting, planar foundations are divided into section and surface‐acting, and volumetric ones are recognized as block ...
