The hypocenters of microseismic events induced by hydraulic fracturing are conventionally located with an initial model established from well logs or perforation shots. In most geological settings, the arrival times are insufficiently explained witho

Vertical seismic profiling (VSP) is an effective technique to provide high-resolution seismic images of the reservoir area. However, the quality of the images is limited by the poor illumination of primary reflection wave. In conventional VSP imaging

During hydraulic fracturing, expansion of internal micro-fractures deforms the rock to different extents. Numerical studies typically assume fixed parameters; however, in the field site, parameters are likely to vary. Error accumulation underlies dev

The traditional methods for ground-penetrating radar (GPR) wavefield simulation suffer from numerical dispersion phenomena and difficulties for models with complex geometry. We propose to use the physics-informed neural networks (PINNs) to solve the

Carbon capture and storage is an effective technique for achieving ‘carbon neutrality’. Seismology plays an important role in detecting and monitoring whether CO2 has been safely sealed. However, active seismic surveys are usually incapable of co
