Falcon和Tamboran完成三口井批量钻探活动

Falcon Oil & Gas 和合资伙伴 Tamboran 已完成三口井批量钻探活动,这是 Beetaloo 次盆地有史以来规模最大、也是首个多井钻探项目。

2025年批量钻井项目中的三口井(Shenandoah South SS2-1H、SS2-3H和SS2-5H)目前已完成钻井、下套管和暂停作业,准备进行增产作业,每口井的水平段长度为3000米。平均钻至目标深度耗时26.7天,钻井和下套管时间在预计的35天之内。

通过改进泥浆系统和使用抗振钻头,钻井效率显著提升。SS2-1H井的日钻井长度达到约1000米,是迄今为止Amungee B段页岩水平段钻井速度最快的井。

目前计划于2025年第四季度对SS2-5H井全长3000米的水平段进行最多60级增产作业,预计在天然气销售开始前,关井前将进行30天的流量测试。2026年上半年,预计将对三口井(包括2024年钻探的第二口井)进行增产作业,并开始天然气销售。

Falcon, Tamboran complete three-well batch drilling campaign

Falcon Oil & Gas and joint venture partner Tamboran have completed a three-well batch drilling campaign, the largest and first multi-well drilling program ever conducted in the Beetaloo Sub-basin.

The three wells of the 2025 batch drilling campaign (Shenandoah South SS2-1H, SS2-3H and SS2-5H) are now drilled, cased and suspended ahead of stimulation, each with a 3,000-m horizontal section. The average drilling to target depth was 26.7 days, with the drilling and casing time delivered within the 35-day forecast.

Modifications to the mud system and use of anti-vibration drilling bits led to increased drilling efficiency. This resulted in reaching ~1,000 m drilled in a day in the SS2-1H well, the fastest horizontal section drilled in the Amungee Member B-shale to date.

Up to a 60-stage stimulation across the full 3,000-m horizontal section of SS2-5H well is now planned in Q4 2025 and is expected to be flow tested for 30 days prior to being shut-in ahead of the commencement of gas sales. In H1 2026, three wells (which includes the second well of the 2024 drilling campaign) are expected to be stimulated ahead of the commencement of gas sales.
