Abstract: In seismic inversion, the subsurface model can be parameterized by a truncated Fourier series, and then, the inversion problem is the inversion of the Fourier coefficients. To improve the ...

The inversion of elastic and fracture parameters from azimuthal seismic data plays a critical role in charactering naturally fractured reservoirs. We propose a Fourier coefficients-based stepwise ...

Convolution is a remarkable property of the Fourier transform, often cited in the literature as the “faltung theorem”. Convolution is a remarkable property of the Fourier transform, often cited in the ...

What Is the Central Limit Theorem? The Central Limit Theorem (CLT) states that if you sample a data population enough times, then the means and standard deviations of the samples will approach a ...

The formalism of the Dirac delta function developed in a previous article allows us to understand the phenomenon of aliasing in a simple and comprehensive way. In a previous article, we established ...
