Amplitude Energy Hits 49m Net Pay at Juliet-1 in Proven Otway Gas Reservoir
Key Takeaways
- Juliet-1 intersected at least 60 metres of gross gas-bearing interval and 49 metres of interpreted net pay in the Waarre C reservoir, reaching total depth of 2,299m TVDSS on 7 September 2026 ahead of schedule and under budget.
- The gas water contact is interpreted as being below total depth, meaning the full gas column was not drilled through — preserving upside in the resource volume that wireline logging will now help quantify.
- Three converging technical signals — elevated gas readings, elevated LWD resistivity, and 49 metres of net pay consistent with offset Waarre C fields — support the probable hydrocarbon interpretation.
- Juliet-1 sits adjacent to the existing Casino, Henry, Netherby pipeline, meaning potential tie-in infrastructure is already in place if the well is developed.
- Wireline pressure and sample data expected within days will be the next material catalyst, informing resource volume estimates and the decision on whether to complete Juliet-1 as a producing well.
Juliet-1 strikes gas: 49 metres of net pay in Waarre C reservoir
Amplitude Energy has intersected a high-quality gas-bearing Waarre C reservoir at its Juliet-1 exploration well in the Offshore Otway Basin, recording at least 60 metres of gross gas-bearing interval and 49 metres of interpreted net pay. The well reached total depth safely on 7 September 2026, ahead of schedule and under budget.
| Parameter | Detail |
|---|---|
| Well name | Juliet-1 |
| Permit | VIC/L24, Offshore Otway Basin |
| Total depth | 2,299m TVDSS |
| Reservoir intersection depth | 2,129m TVDSS |
| Gross pay | At least 60 metres |
| Net pay (interpreted) | 49 metres |
Preliminary drilling and logging data recorded elevated gas readings in the Waarre C reservoir, coinciding with elevated resistivity readings on Logging While Drilling (LWD) tools, consistent with probable hydrocarbon presence. The gas water contact is currently interpreted as being below total depth, a point that carries meaningful implications for the well’s upside potential.

What Waarre C means for investors
The Waarre C formation is the same geological unit intersected in other Waarre C reservoirs at offset fields, giving investors a direct benchmark for reservoir quality and thickness. Juliet-1 is located adjacent to the existing Casino, Henry, Netherby (CHN) pipeline.
Logging While Drilling (LWD) is a technology that records real-time subsurface data as the drill bit advances, including resistivity readings that signal hydrocarbon presence. When those resistivity readings spike in the same interval where elevated gas is detected, that is the technical signature for probable hydrocarbons — and that is exactly what Juliet-1 delivered.
Three technical signals support that interpretation:
- Elevated gas readings recorded in the Waarre C reservoir
- Elevated resistivity on LWD tools coinciding with those gas peaks
- 49 metres of interpreted net pay consistent with offset Waarre C fields
The gas water contact being interpreted below total depth is a particularly positive indicator. It means the productive interval is not yet fully defined at its base — the well did not drill through the entire gas column. That preserves upside potential in the resource volume that wireline logging will now help to quantify.
Results to date are described by the company as in-line with pre-drill expectations for reservoir quality and thickness. This is not a miss. It validates the geological model used to target Juliet-1 as an offset to the CHN fields.
Ahead of schedule: what happens next
The Juliet-1 programme is currently ahead of schedule and budget, with a clear forward work programme now underway. All activities are expected to complete over approximately the next two weeks.
- Wireline logging — pressure and sample data collection in coming days to inform resource volume estimates and determine initial gas composition
- Completion decision — once wireline results are reviewed, a decision on completing the well will be made
- Well clean-up and suspension — clean-up operations to inform reservoir deliverability, followed by suspension of the well
- Laboratory analysis — further work to confirm gas composition, including any non-hydrocarbon gas content such as CO₂, N₂, and H₂S, which have not yet been quantified
One important caveat investors should hold front of mind: no estimate of petroleum reserves or contingent resources is being reported at this stage. The intersection of a gas-bearing reservoir does not, of itself, confirm the presence of commercially recoverable hydrocarbons. Interpretation of the data is ongoing and remains subject to further logging, testing, and evaluation.

Amplitude Energy’s strategic position in southeast Australian gas
The Juliet-1 result sits within a broader portfolio strategy that AEL has been building across the Otway and Gippsland Basins. The company is operator and 50% working interest holder in VIC/L24, with O.G. Energy holding the remaining 50% interest.
One factor that could reduce future development infrastructure requirements, if the well is developed, is Juliet-1’s location adjacent to the existing CHN pipeline. That proximity means potential tie-in options are available without the need for standalone pipeline construction.
AEL’s wider portfolio includes undeveloped discovered resources at the Annie and Manta gas fields, as well as a suite of Otway and Gippsland Basin exploration prospects. The company supplies the southeast domestic gas market through long-term customer contracts while retaining exposure to spot market pricing — meaning successful exploration at Juliet-1 feeds directly into the company’s capacity to grow supply.
Wireline results expected in coming days will be the next material datapoint for investors watching this well. The pressure and sample data collected will shape the resource volume picture and the decision on whether to complete Juliet-1 as a producing well.
