Omega Oil and Gas 已完成位于澳大利亚昆士兰州南部鲍文盆地 PCA 342 的 Canyon-1H 水平评估井项目。

Canyon-1H 已钻至 4,616 米深，套管已下至深井深并固井。重新进入现有的 Canyon-1 直井后，新钻井 1,147 米，其中 Canyon 砂岩层 822 米。在目标层段钻井时，记录到强烈的带荧光的气体显示，表明存在凝析油。

由于井下工具故障，需要临时起降，因此我们决定在 4616 米处停止钻探。到那时，我们已经钻探了足够的储层部分，实现了有效测试 Canyon Sandstone 生产能力的目标。

钻井和套管项目的成功完成使 Omega 在即将到来的多级水力压裂增产、回流和油井测试项目中占据了有利地位。该项目旨在测试能否从二叠纪 Kianga 地层底部极具前景的峡谷砂岩中获得潜在的经济流量。该项目预计将于 2025 年第一季度进行。

Omega Oil and Gas has completed the Canyon-1H horizontal appraisal well project, located in PCA 342 in the Bowen Basin in Southern Queensland, Australia.

Canyon-1H was drilled to a TD of 4,616 m, and casing has been run to TD and cemented. After re-entering the pre-existing Canyon-1 vertical well, 1,147 m of new hole was drilled, including 822 m in the Canyon Sandstone. While drilling in the target section, strong gas shows with fluorescence indicating the presence of condensate were recorded.

A decision was made to halt drilling at 4616 m when an unscheduled trip out of the hole was required due to a downhole tool failure. By that time sufficient reservoir section had been drilled to achieve our goal of a valid test of the Canyon Sandstone’s productive capacity.

Successful completion of the drilling and casing program has put Omega in a strong position for the upcoming multi-stage hydraulic fracture stimulation, flow back, and well testing program. The program aims to test whether potentially economic flow rates can be achieved from the highly prospective Canyon Sandstone at the base of the Permian Kianga Formation. The program is expected to be conducted in Q1 2025.
