Earthquakes are classified as one of the most devastating natural disasters that can have catastrophic effects on environment, lives, and properties. Most recent earthquakes magnitudes greater than > M8. Satellite data, global positioning system, interferometry synthetic aperture radar (InSAR), seismometers such microelectromechanical seismometers, ocean bottom distributed acoustic sensing systems all been used to predict with a high degree success. Despite advances in seismic wave...
Despite exploration and production success in Niger Delta, several failed wells have been encountered due to overpressures. Hence, it is very essential understand the spatial distribution of pore pressure generating mechanisms order mitigate pitfalls that might arise during drilling. This research provides estimates along three offshore using Eaton's transit time method, multi-layer perceptron artificial neural network (MLP-ANN) random forest regression (RFR) algorithms. Our results show...
SUMMARY The Nankai Trough is a locus of slow slip, low-frequency earthquakes, and large magnitude (Mw > 8) earthquakes. It usually assumed that high pore pressure contributes substantially to earthquake dynamics. Hence, thorough understanding the hydraulic regime accretionary prism needed understand this diversity behaviours. We focus on toe by studying data from Hole C0024A, part Seismogenic Zone Experiment (NanTroSEIZE) project, intersected décollement at 813 m below seafloor (mbsf)...
Abstract Accurately determining the mineralogical composition of rocks is essential for precise assessments key petrophysical properties like effective porosity, water saturation, clay volume, and permeability. Mineral volume inversion particularly critical in geological contexts characterized by heterogeneity, such as Upper Rhine Graben (URG), where both carbonate siliciclastic formations are prevalent. The estimation mineral volumes poses challenges that involve linear nonlinear...
A wide range of geophysical methods is used for the exploration deep geothermal resources. It aimsat characterizing fractured network and its capacity fluid/heat extraction. This relieshowever on techniques to 1) image geometry networkbut also 2) characterize petro-physical properties fracture matrix. The challengeis however that inverse problem ill-posed multi-scale.To overcome these challenges, we propose here take a multi-physics multi-scale approach thegeophysical/petro-physical problem....
Despite exploration and production success in Niger Delta, several failed wells have been encountered due to overpressures. Hence, it is very essential understand the spatial distribution of pore pressure generating mechanism order mitigate pitfalls that might arise during drilling. This research provides estimates along three offshore using Eaton’s transit time method. An accurate normal compaction trend was estimated exponent (m=3). Our results show there are magnitude regimes: zone...
