The Lost Cabin Gas Plant project was a CCUS project with a capacity of 0.9Mtpa started in 2013 in
Fremont County, Wyoming, U.S.

ConocoPhillips and Denbury were the companies involved in the project.

It suspended CO2 injection in 2018 when a fire at the plant resulted in the shutdown of its CCUS facility. There was an expectation that operations would restart by the end of 2020 with a lower capture rate of 0.7Mtpa but it did not happen.

As of 2023, a government report notes that the plant is in operation and that the gas plant is now controlled by Contango Oil & Gas. ConocoPhillips divested the plant in 2021 and 2022.
