FACTSHEET FOR PARTNERSHIP FIELD VALIDATION TEST

Three coal zones were individually through pressure-transient injection-falloff tests using a total of 278 tons of CO2 (about 93 tons per coal zone). Coal seams at the test site can sequester more than 1,740 tons of CO2 per acre (30 million scf/acre). Therefore, this project affected only the area immediately surrounding the coalbed methane well.

Analysis of numerous injection/falloff tests in the field, primarily on coalbed methane wells, has led to a better understanding of the requirements for proper injection/falloff testing. Because most of the formations do not flow prior to testing, test design is difficult and many of the testing procedures must be modified during the test itself.
