In indirect BCGSs, hydrocarbon migration distances are highly variable, similar to migration distances in conventional petroleum systems. Approximately 1000 ft (305 m) of vertical migration is proposed for the Clinton-Medina BCGA.<ref name=Ryderandzagorski_2003 /> In direct BCGSs, gas is the dominant migrating hydrocarbon phase, and in indirect BCGSs, oil and gas may be expected to be the migrating fluid phases.
