This is my understanding as well. And the logistics of doing this can be simplified by re-using oil and gas facilities. Regardless of your feelings and levels of skepticism about oil and gas, this seems like the most straight-forward and low-energy path forward to me.

As it stands such projects are net negative.

Currently the largest global carbon capture project in practice is little more than green washing, it's a large Australasian LNG field that will pump back a tiny percentage of the CO2 released by the projects outputs.

The required scale of carbon capture to offset our current annual consumption is huge, we extract on the order of a cubic mile of oil per annum: https://en.wikipedia.org/wiki/A_Cubic_Mile_of_Oil the buildout and the additional energy required to address that is at the scale of the existing oil industry with no profit to be had.

I think it's weird to think of carbon capture and storage as some sort of panacea for climate change. I think it can be a valuable technology that works towards that effort and when combined with reduction in carbon output through greening other technologies (e.g., shipping, airlines, converting to green energy resources, greener concrete) then it will be fine.

The problem is everyone is looking for some solution that is as cheap as burning coal and oil. Maybe there isn't any solution. Maybe if we desire to mitigate climate change that will come at a cost that changes our way of life.

They get paid to use CO2 pumped back in the wells so its a way to subsidize drilling.

Also the monitoring of said CO2 reservoirs is poor with leaks being a concern enough that would negate the whole project.

My favourite solution was in the 2006 ipcc report for recommendations for carbon storage and one is liquifying it and dumping it in the Mariana Trench. Where it would stay for up to 300 years. The best part is that they plainly say it will simply be someone else’s problem so that’s a reason that could go in the pro column of deciding to do this or not haha.
