坦桑尼亚主要氦气勘探公司 Helium One Global 很高兴提供有关 Itumbula West-1（“ITW-1”）运营的以下最新消息。

要点
· 公司已成功重新进入 ITW-1 井，并将该井进一步加深至基岩 168 米，并已达到新的总深度 (TD) 1129 米测量深度 (MD)
· 钻井过程中测量到近乎连续的氦气和氢气，并且明显高于第二阶段钻探覆盖层部分时遇到的氦气和氢气
· 开始准备运行 7 英寸开槽套管和固井作业
· 套管固井到位后，将开始两个区间的扩展井测试 (EWT) 作业；裂缝基岩和断层卡鲁群

详情
公司已成功重新进入 ITW-1 井，并将该井进一步加深至裂缝基岩 168 米，并已达到新的总深度 1129 米 MD。现有井眼条件非常好，使井眼能够高效地重新进入 9 英寸鞋底下方，并随后加深至基岩。

在深化钻井过程中，钻井过程中几乎连续出现氦气和氢气显示。这些显示的频率一直持续到钻井深度，并且明显高于第二阶段钻探覆盖层部分时遇到的显示频率。

下一阶段的作业现在涉及准备井筒以运行 7 英寸开槽套管并将其固定到位。一旦完成，公司将在井中运行由油管和封隔器组成的完井管柱，以便在 EWT 期间对两个区域（裂缝基底和断层 Karoo 群）进行多次测试。

公司将在适当的时候提供进一步的更新。

首席执行官 Lorna Blaisse 评论道：
“我们很高兴能够按计划重新进入并加深 ITW-1 井。在钻探更深的部分时看到氦气和氢气继续出现是非常令人鼓舞的，我们期待通过 EWT 进一步评估这些结果。

我要感谢更广泛的团队安全执行这一钻探阶段，以及坦桑尼亚矿产和矿业委员会的持续支持。”

Helium One Global, the primary helium explorer in Tanzania, is pleased to provide the following update on Itumbula West-1 ("ITW-1") operations.

Highlights
· The Company has successfully re-entered and deepened the ITW-1 well a further 168m into the Basement and has reached a new total depth ("TD") of 1129m measured depth ("MD")
· Near-continuous helium and hydrogen shows measured whilst drilling and were notably higher than those encountered whilst drilling the overburden section during Phase II
· Commenced preparations for running 7" slotted casing and cementing operations
· Once casing is cemented in place, extended well test ("EWT") operations will commence across two intervals; fractured Basement and faulted Karoo Group

Details
The Company has successfully re-entered and deepened the ITW-1 well a further 168m into the fractured Basement and has reached a new TD of 1129m MD. The existing hole conditions were very good and enabled the wellbore re-entry beneath the 9?" shoe, and subsequent deepening into the Basement, to occur efficiently.

Whilst deepening the well, near-continuous helium and hydrogen shows were encountered whilst drilling. The frequency of these shows continued to TD and were notably higher than those which were encountered whilst drilling the overburden section during Phase II.

The next phase of the operations now involves preparing the wellbore for running the 7" slotted casing and cementing it in place. Once this is complete, the Company will then run a completion string in the hole comprising of tubing and packers to allow multiple testing of the two zones (the fractured Basement and the faulted Karoo Group) during the EWT.

The Company will provide further updates in due course.

Lorna Blaisse, Chief Executive Officer, commented:
"We are pleased that we have been able to re-enter and deepen the ITW-1 well as planned. It has been very encouraging seeing the helium and hydrogen shows continuing whilst drilling this deeper section, and we look forward to evaluating these results further through the EWT.

I'd like to extend my thanks to the wider team in a safe execution of this drilling phase, as well as the continued support from the Ministry of Minerals and Mining Commission in Tanzania."
