This study explores the feasibility of implementing in-situ CO2 recycling for sequestration as a fit-for-purpose developmental strategy for a Malaysian gas field characterized by an initial CO2 content of approximately 60%. Through a comprehensive analysis encompassing key field parameters, the study aims to optimize cumulative gas production while effectively managing CO2 storage. A robust compositional dynamic model is constructed. The model facilitates the recycling of produced CO2 between gas producers and CO2 injectors, while the introduction of CO2 tracers for each well enables the differentiation of CO2 sources, enhancing shutdown strategies and parameter optimization.
Field Overview and Field and Storage Development Plan (FSDP) Concept
The focus of this feasibility study is an offshore gas field in a predevelopment stage. The geological interpretation suggests a predominantly shoreface depositional environment.
