Abstract

Shale gas reservoirs have been proposed as feasible choices of location for injection of CO2 because this method could enhance recovery of natural gas resources, while at the same time sequester CO2 underground. In this paper, a fully coupled multi-continuum multi-component simulator which incorporates several transport/storage mechanisms is developed. Knudsen diffusion and gas slippage are included in the flow model. An extended Langmuir isotherm is used to describe the adsorption/desorption behavior. In addition, a hierarchical approach which integrates EDFM with MINC concept is adopted. Fully implicit scheme is applied for discretizing fluid equations. Different injection strategies including huff-n-puff scenario are evaluated to provide insights for optimizing production of multi-fractured horizontal well. Results show that CO2 injection can be an effective approach with great application potential for enhancing shale gas recovery.
