• We analyze the stress inversion performance under different stress states using synthetic tests with varying pore pressure • Stress ratio R changes and pore pressure are negatively correlated when R < 0.6 • This correlation holds for all stress regimes and is confirmed using data from fluid-induced seismicity and corresponding injection rates
