There has been so much research into caprock permeability/stability, we know that shit. People have produced several atlases full of possible CO2 sequestration reservoirs with different geological properties, injectivity and maturity based on 3D seismics and core sample drillings etc.
CO2 sequestration is ready to go. Just like CO2 capture is ready to go. You have several actors commissioning projects now in Europe with 20-40 megatonnes stored per year.

That's good to know.
AFAIK, that research did not make into the mainstream news. But then, geological research never does.
Rocks react quite well. Most are stable, some others absorb the gas and become stable.
It's water that doesn't deal well with it. It carries the CO2 into any place that it goes. What concerns me is that it's common to extract methane from places where it's trapped between a solid rock and a porous one full of water. That does not look like a proper place to inject CO2, but it's the place that every article about CO2 entrapment talks about.
