Experimental Simulation Investigation on Mechanism and Criterion of Impact‐Induced Rockburst in Gaoloushan Deep Tunnel

open access: yesEnergy Science &Engineering, EarlyView.
ABSTRACT During the excavation of a deep‐buried tunnel by the drilling and blasting method, the dynamic stress of blasting may cause the disorderly release of high energy in the rock mass during the blasting process of deep high‐energy rock. Blasting vibration is one of the main factors inducing dynamic disasters (such as rockbursts) in the surrounding

Seismic hazard assessment of the Three Gorges Project

open access: yesGeodesy and Geodynamics, 2013
Abstract:Seismic monitoring data for the past 50 years in the Three Gorges Reservoir area show that the reservoir head area is a typical weak seismic region with low seismicity before impoundment and that the epicenters were concentrated in the east and west sides of the Zigui Basin, most of which were natural tectonic earthquakes.

Bolt Anchorage Quality Levels Classification Method Based on HO‐VMD‐CNN‐BiLSTM

open access: yesEnergy Science &Engineering, EarlyView.
First, the original ultrasound‐guided wave signal data is decomposed into multiple sub‐signals with varying frequencies using VMD to capture the multi‐scale features within the data. Second, the decomposed and noise‐reduced signal, processed by the HO‐VMD algorithm, is input into the CNN for further feature extraction through convolution and pooling ...

Analysis of Gas‐Bearing Properties of Shale Reservoirs: A Comprehensive Analysis Based on Field Interpretation and Logging Interpretation

open access: yesEnergy Science &Engineering, EarlyView.
ABSTRACT Shale gas, as an important component of unconventional natural gas, plays a crucial role in resource development. This paper proposes a comprehensive analytical method that combines field analysis and well logging interpretation to evaluate gas content in shale reservoirs.

Quantitative Evaluation of Sand Body Connectivity Based on the Support Vector Machine Algorithm: A Case Study of the Putaohua Oil Reservoir in the Daqing Oil Field, Songliao Basin, China

open access: yesEnergy Science &Engineering, EarlyView.
A support vector machine (SVM) algorithm was applied to quantitatively predict the connectivity of the sand bodies. Verification using dynamic and static data demonstrated that the prediction accuracy of the algorithm reached 88%. The quantitative sand body connectivity results were used to establish a single sand body model.

Geological Screening for CO2 Storage in Deep Saline Aquifers in the Lower Mainland British Columbia (LMBC), Canada

open access: yesGreenhouse Gases: Science and Technology, EarlyView.
ABSTRACT Deep saline aquifers and depleted reservoirs are prime candidates for CO2 storage, but feasibility assessments remain limited in regions with little oil and gas activity, such as the Lower Mainland of British Columbia (LMBC), Canada. This study evaluates the CO2 storage potential of the Georgia Basin strata beneath the LMBC, focusing on three ...

Phanerozoic Large Igneous Province, Petroleum System, and Source Rock Links

open access: yesGeophysical Monograph Series, Page 191-228., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.
