欧米茄石油和天然气公司 (Omega Oil and Gas) 宣布，在从壳牌 QGC 致密气砂岩 (TGS) 项目中解放出来后，Ensign 965 号钻机于 9 月 6 日开始运往位于澳大利亚博文盆地的 Canyon-1H 项目。欧米茄石油和天然气公司是潜在商业区 (PCA) 342 和 PCA 343（峡谷气田项目）的 100% 持有者。

在钻机成功调动和验收后，Canyon-1H 井预计将于 2024 年 9 月 20 日左右开钻。

Ensign #965 钻机是 ADR-1500 型号钻机，吊钩载荷为 750,000 磅。该型号钻机在澳大利亚各地钻探类似深度的井方面有着良好的记录。如果需要，#965 钻机有能力钻探超过 Canyon-1H 计划总深度的井，并且具有备用作业能力。

Ensign Rig #965 的设备、工作人员和哈里伯顿提供的综合钻井服务将在为壳牌完成附近三口类似的水平井后“热身”到位。这是 Canyon-1H 项目一项重要且经过深思熟虑的风险缓解策略。

计划钻探 600-1,100 米水平段（取决于井况）。在分析和整合井结果并最终确定完井设计后，Omega 计划完成多级水力压裂增产、回流和生产测试。Canyon-1H 水平井旨在测试能否从二叠纪 Kianga 地层底部极具前景的 Canyon 砂岩中获得潜在的经济流量。

厚而迷人的二叠纪序列横跨 Omega 峡谷气田项目的整个区域，由峡谷砂岩和 Omega 确定的其他砂岩（非正式名称为上 Kianga 组的塔斯马尼亚砂岩和卡巴温砂岩）组成。

水平井提供的测试储层表面积比垂直井大得多，因此选定的储层区间最有可能以潜在的商业速率流动。这种方法还使 Omega 能够获得早期评估数据，从而快速推进油田的进一步评估和开发。

Mobilization of the Ensign Rig #965 to the Canyon-1H project in Australia’s Bowen Basin commenced on 6 September following release from the Shell QGC Tight Gas Sands (TGS) project, announced Omega Oil and Gas, the 100% holder of Potential Commercial Area (PCA) 342 and PCA 343 (the Canyon Gas Field project).

Following successful rig mobilization and acceptance, the Canyon-1H well is anticipated to spud on approximately 20 September 2024.

Ensign #965 rig is an ADR-1500 model rig with a hook load of 750,000 lbs. This model rig has a proven track record of drilling wells of similar depths throughout Australia. Rig #965 has the capacity to drill beyond the planned total depth of Canyon-1H with spare operational capability, should it be required.

Ensign Rig #965’s equipment, crew and integrated drilling services from Halliburton will arrive “warm” after completing three similar horizontal wells nearby for Shell. This is an important and deliberate risk mitigation strategy for the Canyon-1H Project.

It is planned to drill a 600-1,100 m horizontal section (depending on hole conditions). After analyzing and integrating the results of the well and finalizing the completion design, Omega plans to complete a multi-stage hydraulic fracture stimulation, flowback and production test. The Canyon-1H horizontal well aims to test whether a potential economic flow rate can be achieved from the highly prospective Canyon Sandstone at the base of the Permian Kianga Formation.

The thick, attractive Permian sequence that extends across the entire area of Omega’s Canyon gas field project comprises the Canyon Sandstone, together with other sandstones identified by Omega (informally named the Tasmania and Cabawin Sandstones of the upper Kianga Formation).

A horizontal well provides a vastly greater reservoir surface area for testing than a vertical well, thus giving the selected reservoir interval the best chance to flow at a potentially commercial rate. This approach also allows Omega to obtain early appraisal data, enabling rapid progress toward the further appraisal and development of the field.
