3D Energi Limited（公司名称：TDO；ASX：TDO）欣然提供以下关于维多利亚州奥特威盆地近海 VIC/P79 勘探许可证内 Charlemont-1 天然气勘探/评价井钻探作业的最新信息（图 1）。

亮点：
Waarre C、B 和 Waarre A 砂岩中可能存在天然气；
天然气读数和测井电阻率升高与油气存在相符；
Charlemont-1 钻井平台已达到比预期更浅的总深度，在 Waarre A 砂岩中钻探约 70 米，由于地层压力高于预期，钻井被迫停止；
正在评估进一步电缆测井作业的方案；

Charlemont-1 钻井平台的目标是 Charlemont B 勘探区（参见图 2），该勘探区位于坎贝尔港以东约 55 公里处，水深约 110 米。Charlemont

B 是勘探链一端的倒数第二个勘探区，另一端是 La Bella 天然气发现区，位于其东侧约 7 公里处（参见图 2-4）。所有中间勘探区（包括 Charlemont B）的地球物理响应与 La Bella 相似。因此，Charlemont-1 井有潜力对 La Bella 方向的中间勘探区进行评估。

作业状态：
Charlemont-1 井于 2025 年 12 月 10 日晚上 7:15（澳大利亚东部夏令时）由 Transocean Equinox 号钻井船开钻。据 2026 年 1 月 2 日报告，在钻进至 2552 米 MDRT1,2 处的 Waarre C 地层时，由于地层压力高于预期并伴有明显的天然气显示，钻井作业暂停。随后，在 Charlemont-1 井中成功安装了 7 英寸衬管。

2026年1月2日晚，Waarre C油藏的钻探工作重新启动。在Waarre C砂岩层中记录到气体读数升高（参见表1和表2），这与测井电阻率读数升高相吻合，表明Waarre C砂岩层中可能存在油气。需要进行进一步的测井作业以全面评估油气的性质和范围。

随着钻井的进行，在Waarre B砂岩层段（从2664米MDKB至2683米MDRT1,2处的Waarre A主要目标层）记录到气体读数升高，并持续穿过Waarre A层至2753米MDKB（参见表1和表2）。Waarre B和Waarre A砂岩层中气体读数升高与随钻测井（LWD）工具测得的电阻率升高相吻合，表明Waarre B和Waarre A砂岩层中可能存在油气。

在2753米MDKB处，井钻遇一个地层压力高于预期的区域，达到作业容差范围。因此，钻井作业已提前结束，未达到计划的总深度2862米MDKB，目前正在评估后续电缆测井作业的方案。

需要进行测井作业，以全面评估Waarre B和Waarre A层中任何油气的性质和范围，并确定其与Waarre C层的潜在连通性。

我们将通过关键的作业里程碑提供进一步的更新信息。3D Energi

执行主席
Noel Newell评论道：“我们对多个Waarre储层中存在天然气的早期迹象感到无比兴奋。测井作业对于评估这些迹象的质量和范围至关重要，公司对推进评估阶段的计划保持乐观。

在Waarre C层中发现可能的油气意义重大，因为在钻探之前并未预料到该区域存在油气。这一结果可能对Charlemont趋势上倾方向的勘探前景产生进一步的积极影响，特别是那些目前尚未得到地震直接油气指标（DHI）支持的区域。我们将在钻探计划结束后对此进行密切评估。”

瓦尔雷砂岩叠置储层中天然气的存在降低了查勒蒙特地层带上倾方向直接燃烧装置（DHI）勘探的风险，最终促成了拉贝拉气田的发现。如果评估成功，该气田群有望成为奥特威盆地最大的天然气藏之一。

3D Energi Limited (the 锟紺ompany锟�; ASX:TDO) is pleased to provide the following update on drilling operations at the Charlemont-1 gas exploration/appraisal well within VIC/P79 exploration permit, offshore Otway Basin, Victoria (Figure 1).

Highlights
锟� Probable gas presence in the Waarre C, B and Waarre A sandstones
锟� Elevated gas readings and log resistivity are consistent with hydrocarbon presence
锟� Charlemont-1 has reached total depth shallower to prognosis, approximately 70m into the Waarre A, after higher than anticipated formation pressures required a cessation of drilling.
锟� Scenarios for further wireline logging operations are being evaluated

Charlemont-1 is targeting the Charlemont B Prospect (refer to Figure 2) and is located approximately 55km offshore from Port Campbell, in water depths of approximately 110m.

Charlemont B is the penultimate prospect at one end of a prospect chain, with the La Bella gas discovery at the other, approximately 7km to the east (refer to Figures 2-4). All intervening prospects 锟� including Charlemont B 锟� share similar geophysical response as La Bella. Accordingly, Charlemont-1 has the potential to appraise the intervening prospects towards La Bella.

Operations Status
The Charlemont-1 well was spud at 7:15pm AEDT on 10 December 2025 by the Transocean Equinox. As reported on 2 January 2026, a 7锟� liner was successfully installed in the Charlemont-1 well after drilling was paused on entry to the Waarre C at 2552 metres MDRT1,2 , following higher-than-anticipated formation pressures in conjunction with significant gas shows.

Drilling into the Waarre C reservoir re-commenced on the evening of 2 January 2026. Elevated gas readings were recorded across the Waarre C sandstones(refer to Tables 1 and 2), and coincide with elevated resistivity readings on wireline, consistent with probable hydrocarbon presence in the Waarre C sandstones. Further wireline logging is required to fully evaluate the nature and extent of the hydrocarbons.

As drilling proceeded, elevated gas readings were recorded across Waarre B sandstone intervals from 2664 metres MDKB into the Waarre A primary target at 2683 metres MDRT1,2 , and continued through the Waarre A to 2753 metres MDKB (refer to Tables 1 and 2). Elevated gas readings in the Waarre B and Waarre A sandstones coincide with elevated resistivity on the LWD tool and is consistent with probable hydrocarbon presence in both the Waarre B and Waarre A sandstones.

At 2753m MDKB, the well intersected a zone with higher-than-anticipated formation pressures, reaching operational tolerances. Accordingly, drilling operations have been concluded prior to the planned Total Depth of 2862 metres MDKB and scenarios for further wireline logging operations are being evaluated.

Wireline logging is required to fully evaluate the nature and extent of any hydrocarbons in the Waarre B and Waarre A, and to determine any potential connectivity with the Waarre C.

Further updates will be provided through key operational milestones.

Executive Chairman锟絪 Comments
Noel Newell, Executive Chairman of 3D Energi said 锟絎e are incredibly excited by early indications consistent with gas presence in multiple Waarre reservoirs. Wireline logging will be critical in assessing the quality and extent of these indications, and the Company remains optimistic as it continues to plan to progress to the evaluation phase.

The identification of probable hydrocarbons in the Waarre C is significant, as hydrocarbons were not anticipated in this zone prior to drilling. This outcome may have further positive implications for up-dip prospects along the Charlemont Trend, particularly those not currently supported by existing Direct Hydrocarbon Indicators (DHIs) on seismic. We will be evaluating this closely at the conclusion of the drilling program.

The presence of gas across stacked Waarre sandstone reservoirs de-risks the up-dip prospects with DHIs in the Charlemont Trend, culminating with the La Bella discovery. If successfully appraised, this cluster could be among the largest gas pools in the Otway Basin锟�.
