Amplitude Energy (ASX:AEL) Down 20% After Elanora 1 Misses, Isabella Is the Next Shot

Amplitude Energy  The Market Was Positioned for Gas, It Got Water

Amplitude Energy (ASX:AEL) saw a sharp sell-off, down around 20%, after updating the market on drilling at the Elanora 1 exploration zone in the offshore Otway Basin.
The objective was straightforward. The well was targeting a gas-bearing reservoir known as Waarre A.

Operationally, the update was clean. They reached total depth safely and ahead of schedule. The problem was what they found once they got there.

Based on the logs and drilling data, there were no elevated gas readings. Management’s interpretation is that the reservoir is water-bearing, not gas-bearing.
In simple terms, the well appears to have missed the outcome the market was positioned for. That is why the share price reacted so aggressively.

Isabella Is the Optionality for Amplitude Energy

Amplitude Energy is not stopping at Elanora 1. The next step is a sidetrack, essentially drilling a new branch wellbore, to test a nearby prospect called Isabella prospect.

They are guiding to roughly 14 to 18 days to execute the sidetrack, which keeps the timeline tight and maintains momentum on the campaign.
If Isabella comes in as a success, the plan is to move straight into evaluation. That could include running the well through a full appraisal pathway, and if results support it, potentially casing and

completing the well with a subsea tree and conducting a flow test.

From there, the intention would be to suspend the well ready for development, so it can be brought into the broader East Coast supply project when the project moves into execution mode.
So the message is pretty clear. Elanora did not deliver, but they have a near-term second shot lined up, and if Isabella works, they are positioned to convert that success into a development-ready asset quickly.

Water Bearing Result, Lower EV, Higher Pressure on Isabella

Management’s message is basically this: Elanora was disappointing, but it does not change their view on the broader opportunity set. There are still other targets, including different sands, that remain prospective.

That said, the market reaction makes sense because Elanora 1 was a binary event.

When the primary target reads as water-bearing, it removes a meaningful piece of the near-term upside that investors were positioned for. In other words, the scenario that was being priced in, a gas-bearing reservoir that could be commercialised, has been taken off the table for now.

So investors are doing what they always do in these moments. They are marking down the expected value of the program. Less perceived probability of success and a lower near-term value outcome typically means the market immediately prices in less economic value than it was assuming before the drill result.
