Paper Number: ARMA-2023-0403
... to wellbore breakouts and acoustic emission experiments of cores, the ratio between σh max and σh min is 1.165. The horizontal principal stress of the reservoir increases with the increase of Young's modulus and pore pressure. The conclusion is that high-precision geomechanical models can effectively serve...

Paper Number: ARMA-2023-0138
.... Underground accidents seriously increase the time and cost of construction operations. It is estimated that at least 10% of the average well budget is used for unplanned operations due to wellbore instability (Sheng, 2006; Wei, 2012). On the other hand, the inaccuracy of geomechanical modeling makes...

... the Full-Effective-Stress (FES) method. This new method uses a geomechanical model to account for stress changes caused by the salt dome and the state boundary surface of the rocks to account for the contributions of all three principal stresses to the rock velocity. In this study, we develop a 3D...
