Abstract
Despite the extensive application of artificial neural networks in seismic inversion, their effectiveness is often hampered by the limited availability of labeled data. To address this challenge, we introduce a novel method for seismic impedance inversion. Our approach integrates a physics-driven cycle network with a Conditional Generative Adversarial Network (CGAN) and a convolutional model. Employing seismic data as input, the CGAN capitalizes on inherent information to minimize non-uniqueness during inversion. Furthermore, the convolutional model, acting as a physics-informed operator, reverts the derived impedance data back to seismic form, enabling simultaneous training of neural networks with labeled and unlabeled data, fulfilling the seismic-to-seismic cycle. The proposed method is demonstrated to be effective on tests using both theoretical models and field data.
期刊介绍:
Journal of Geophysics and Engineering aims to promote research and developments in geophysics and related areas of engineering. It has a predominantly applied science and engineering focus, but solicits and accepts high-quality contributions in all earth-physics disciplines, including geodynamics, natural and controlled-source seismology, oil, gas and mineral exploration, petrophysics and reservoir geophysics. The journal covers those aspects of engineering that are closely related to geophysics, or on the targets and problems that geophysics addresses. Typically, this is engineering focused on the subsurface, particularly petroleum engineering, rock mechanics, geophysical software engineering, drilling technology, remote sensing, instrumentation and sensor design.
