A UTV was outfitted with a methane quantification system to access remote sites.
Natural gas audits were conducted at 11 remote sites – 7 had methane emissions.
The minimum cumulative methane emissions rate was 5.3 ± 0.23 kg per hour.
The average emissions from 5 coalbed methane wells was 1.9 g per hour.
A non-leaking coalbed well was later found to be vented at a rate of 15.8 SCFM.
