Amplitude Energy Limited provides the following update
on drilling operations at the Elanora-1 exploration well in the Offshore Otway Basin, Victoria.
Elanora-1 is an exploration well located in permit VIC/L24 within Commonwealth waters, approximately
6km south-west from a tie-in point in the existing Casino, Henry, Netherby (CHN) pipeline. Amplitude
Energy is operator and 50% interest holder in VIC/L24 with O.G. Energy holding the remaining 50% interest.
The Elanora-1 8 锟�-inch hole section penetrated the primary Waarre A reservoir target and reached the
planned Total Depth (TD) of 1,857 metres TVDSS1 at approximately 01:30 AEST on 10 February 2026, safely
and without material incidents. TD was reached in 15 days from spud date, well ahead of budgeted
schedule.
Preliminary drilling and logging data recorded no elevated gas readings in the primary target Waarre A
reservoir (intersected at 1,766 metres TVDSS). The reservoir is interpreted to be water-bearing.
Forward plan
Elanora-1 will now be plugged and a sidetrack into the Isabella prospect will be drilled as planned, which is
expected to take approximately 14-18 further days. Isabella lies immediately adjacent to Elanora, also in
the VIC/L24 permit.
In the event of success in the sidetrack, evaluation of the discovery through Logging While Drilling (LWD)
will be conducted immediately to assess the gas composition and quality of the reservoir. The sidetrack is
planned to be cased and completed with a sub-sea tree upon success, incorporating a flow test, and then
suspended ready for development as part of the East Coast Supply Project (ECSP).
Managing Director and CEO Jane Norman commented that 锟絎hile the result at Elanora is disappointing we
continue the ECSP campaign with the Isabella prospect, targeting a separate reservoir to that tested by
Elanora. As previously communicated, on success Isabella is intended to be a producing field for the ECSP,
while evaluation of Elanora was intended to inform our longer-term Otway Basin exploration and
development plans. The result at Elanora, which was targeting Waarre A sands, does not impact our view
of the probability of success of Waarre C sands targets such as Isabella, Juliet or Nestor.锟�
