Amplitude Energy (ASX:AEL) said drilling operations at the Elanora-1 exploration well in the Offshore Otway Basin, Victoria, reached the the primary Waarre A reservoir target, which recorded no elevated gas readings, according to a Tuesday filing with the Australian bourse.
Preliminary drilling and logging data showed that the reservoir is water-bearing, the filing said.
The well will now be plugged and a sidetrack will be drilled into the adjacent Isabella prospect, per the filing.
