Data is not real-time

Typically it takes one month to collect sample before it is sent

to the laboratory for analysis. Although the analysis probably

only takes a week, it could still be another three weeks before

the technician is back at the site to collect the next sample

bottle. By the time the gas quality data is entered into the flow

computer it could be anywhere from 1-2 months old.

Data is not accurate

Although the lab analysis is very accurate it is only as good

as the sample handling practices that were used to obtain the

sample. IF the sample bottle is not properly purged or clean

when it was installed then the analysis data will be corrupted.

The error gets magnified when applied across a whole month

of gas production.
