Fully Coupled Near-Wellbore Multiphase Poromechanics Project Details
| Abstract |
This research overview focuses on the numerical modeling of multiphase flow and poromechanical deformations in the near-wellbore region during geological carbon dioxide storage. High-rate and long-term CO2 injection can induce significant wellbore deformations and create potential leakage pathways, threatening reservoir integrity. To address these risks, the study utilizes the open-source multi-scale and multi-physics simulator, GEOS, to model three-dimensional coupled processes. The governing equations for rock matrix mechanical deformations and multiphase compositional fluid flow are solved simultaneously using a fully coupled finite element (FE) and finite volume (FV) approach. The simulator's accuracy is validated against multiple analytical solutions for multiphase flow and wellbore mechanics. The primary focus is on short-term processes
near injection wells, capturing joint stress evolutions, rock deformations, and compositional transport. This modeling framework provides critical guidance for evaluating wellbore stability, preventing mechanical damage, and mitigating CO2 leakage risks. Due to the reliance on the published paper, specific experimental site data or long-term chemical reaction coupling are not detailed, representing a boundary to the current simulation scope.
