Abstract

In this study, a multiphase flow-geochemical-thermal reservoir simulator, CMG STARS, was used to build a reliable reaction module of the CO2 hydrate formation based on laboratory test results in order to investigate the behaviors of CO2 hydrate formation. This research was based on experiments conducted in previous studies by the team from the National Taiwan University of Science and Technology (NTUST). For the experimental data matching, a sensitivity analysis was conducted to understand the effects of flow property, reaction, and thermal property parameters on the behaviors of CO2 hydrate formation. This study successfully established a CO2 hydrate reaction module based on a good history matching. Both the experiment and simulation demonstrated that the CO2 hydrate is formed at the interface between the water and gas. The concentration, accumulation, and distribution of the CO2 hydrate affected by the free gas transport was observed in the simulation.
