They know gas exists from previous exploration so will want to investigate further:
"Although the well was swabbed, only
a minor and slow pressure build-up was observed and a gas flow was not
established. Because of the shallow depth of the well damage to the formation,
as a result of the drilling process and/or the cementing of the production
string, seems the most likely cause of this result.
Monitoring of the pressure build-up is continuing while all the possible causes
for the result are investigated and remedial steps are considered".
