- • Storage sites for CO₂ are often complex and heterogeneous, requiring detailed mapping of formation members and structure
- • Pressure modeling is important when understanding how CO₂ will disperse across and percolate upward through the storage formation
- • Injection modeling is important for optimization of CO₂ sequestration projects, both from a well design and operational management perspective

CO₂ PLUME MODELING:
A CO₂ plume model is a reservoir simulation model that deals specifically with the dispersion of CO₂ in the subsurface after injection
