CO2 Structural Trapping: Maximum Storage Capacity
Upon injecting CO2 into a multi-layer heterogeneous reservoir,
having a layer thickness of 50 m (spill height being the same);
with a reservoir lateral extent of 2 km;
with only one injection well responsible for the filling of a region of extent 1 km along the anticline,
with a CO2 density of 550 kg/m3;
with an average multi-layer porosity of 30%;
with the formation permeability of 0.1 – 1 Darcy;
1. what should be approximate maximum storage capacity of the system in Mt of CO2 per km of anticline?
2. Do we need any other critical parameter that remains missing in this query?
3. For the above case, will we have a control over drainage rate for various injection rates?
4. And, for the above scenario, would it remain feasible for buoyant force to dominate over injection pressure
(a) when the height of individual layer remains to be lesser than the height of spill point; and
(b) when the height of individual layer remains to be greater than the height of spill point?
