Abstract Development and monetization of the gas fields with high carbon dioxide (CO2) content is one of the Petronas’s strategies to support their sustainability agenda and meet the gas demand. The key challenge associated with this type of development is producing massive amount of CO2 which will exceed the step-wised targeted limit of GHG & CO2 emission reduction towards net zero carbon emission by 2050. Decarbonization seems crucial for sustainable development and, hence, sequestration of produced CO2 is identified as the most pragmatic solution going forward. In this paper feasibility of recycling the produced CO2 for sequestration purpose as part of field development plan for a Malaysian gas field with initial ~60% of CO2 content was studied. The main objective of this study was to investigate the possibility of simultaneous gas production and CO2 injection in the same geological formation during field development. The impact of CO2 sequestration back into the same field on important parameters including hydrocarbon reserve, recovery factor, production profile, CO2 breakthrough time, produced gas quality, and overall project cost were investigated, and the cumulative gas production and effective CO2 storage volume as main objective parameters were optimized. A full compositional dynamic model with proper CO2 storage features was constructed. The recycling option of produced CO2 was activated between gas producers and CO2 injectors in the model. Two CO2 tracers for e...
