... We propose a method to calculate the wavefield in the frequency domain at a target area and receivers with reduced computational cost, using the recursive Patched Green Functions method. In this method, the target area and outside-target area Green’s functions are calculated by dividing each...

... We want to show a framework to solve geophysical inversion problems using a gated based quantum computer. The resultant quantum algorithm belongs to the quantum search algorithm class where the query is a forward modelling calculation, and we look for the minimum residual. This quantum algorithm...

... geophysics applied geoscience bnn ifwi multilayer perceptron calculation We introduce and analyze implicit full-waveform inversion (IFWI), which uses a neural network to generate velocity models and perform full-waveform inversion (FWI). IFWI carries out inversion by linking two main networks...

... We present a semi-automated workflow to statistically evaluate relationships between faults and production. First, we estimate 3D faults and fault orientations using a 3D-CNN. Next, we apply fast marching for a shortest path calculation to faults. This creates a 3D volume of distances with each...
