The overall objective of this task is to test the technical viability of injecting CO{sub 2} into the Fruitland Coal to displace methane from the coal and to mitigate CO{sub 2} emissions that are a consequence of primary coalbed methane production from surrounding wells in the area. To evaluate this technical viability, a field test was conducted and the test is being interpreted using data measured in WRIs laboratory, as well as using Amocos state-of-the-art coalbed methane simulator. Also, a second pilot of the process is being evaluated using the simulator. Ultimately, the technology developed will be applied to a Wyoming coal.
