ConocoPhillips did not disclose to CNBC which bitcoin miner it sells to, nor how long the pilot project has been underway, but what typically happens is that a company like Denver-based Crusoe Energy Systems places a shipping container full of thousands of bitcoin miners on an oil well, then diverts the natural gas into generators, which convert the gas into electricity that is then used to power the miners.
