Enhanced Oil Recovery

[caffeinated21]

Right now, you’ve got two real choices for Using CO2: Slickster conversion to petrol or dirt generation through carbon skimmers.

Slicksters are fun but the numbers needed to process a meaningful quantity of CO2 are a giant FPS hit. 

Dirt is great but at some point you have enough for farming, and composts are labor intensive. 
 

So: what if oil wells, in addition to accepting water, also accepted liquified CO2? This is done in real life (https://en.m.wikipedia.org/wiki/Enhanced_oil_recovery) the liquification requirement, especially given oil biome tends to be hot, gives an interesting infrastructure challenge.
