Postrift stress field inversion in the Potiguar Basin, Brazil – Implications for petroleum systems and evolution of the equatorial margin of South America

open access: yesMarine and Petroleum Geology, 2020
Rifting and related normal stress regime in the equatorial continental margin of Brazil ceased during the Late Cretaceous, when the stress regimes in eastern South America and West Africa changed to induce strike-slip or reverse motion. In this study, we

Inversion of horizontal in situ stress field based on wide-azimuth seismic data

open access: yesJournal of Geophysics and Engineering, 2022
In situ stress is a significant rock mechanics parameter, which is widely used in many aspects of the petroleum industry. Horizontal in situ stress is an important part of in situ stress.

The present‐day stress field in the Zagros Fold-Thrust Belt of Iran, from inversion of focal mechanisms

Journal of Geodynamics, 2021
The knowledge about spatial variation of stress field is an important step in the identification of geodynamic and seismotectonic characteristics. Inversion of focal mechanism solutions is one of the most common methods for determination of stress field ...

Improvement of turbulence model for predicting shock-wave–boundary-layer interaction flows by reconstructing Reynolds stress discrepancies based on field inversion and machine learning

The Physics of Fluids, 2023
Reynolds-averaged Navier–Stokes (RANS) models have been the mainstay of engineering applications in recent years, and this trend will likely persist in the coming decades.

Improvement of the algebraic stress model for separated flows based on field inversion and machine learning

The Physics of Fluids, 2023
Due to the difficulties of precisely calculating the turbulence intensity within the separated shear layer using traditional turbulent models, computing strongly separated flows is a key task of considerable interest.
