    Three coal zones were individually through pressure-transient injection-falloff tests using a total of 278 tons of CO 2 (about 93 tons per coal zone). Coal seams at the test site can sequester more than 1 740 tons of CO 2 per acre (30 million scf/acre). Therefore this project affected only the area immediately surrounding the coalbed methane well.

    If an injection/falloff test is conducted by injecting water the pressure in natural fracture system remains above than critical desorption pressure and single-phase flow conditions will prevail during the test. Further the reservoir behaves as a single porosity system since the coal matrix is not affected during the test.
