Abstract

In this paper, shale-gas-field data have been evaluated and incorporated in simulations for both carbon dioxide (CO₂) enhanced-gas-recovery (EGR) and refracturing-treatment purposes. This comprehensive sensitivity study helps in understanding the key reservoir and fracture properties that affect production performance and EGR in shale-gas reservoirs. The findings of this study recommend initial hydraulic refracturing of shale reservoirs for enhancing gas production, followed by CO₂ injection at a later time.
