振幅侧线钻井在维多利亚州近海伊莎贝拉附近与天然气层相交

Amplitude Energy 在维多利亚州近海奥特威盆地 VIC/L24 许可证的 Isabella 勘探区 ST-1 侧钻井平台达到总深度,在主要 Waarre C 储层目标中与含气砂层相交。

8½英寸钻孔段在1738米TVDSS处穿透了Waarre C层,并达到了计划的总深度1788米TVDSS。初步钻井和随钻测井数据显示,气体读数升高与电阻率增加同时出现,这与可能存在油气相符。

为支持资源估算和天然气成分分析,公司计划在未来几天进行电缆测井,以获取压力和样品数据。评估完成后,公司将决定是否采用海底采油树完成ST-1井的开采。如果完成开采,该井将进行流量测试,并暂停开采,以备未来作为ECSP项目的一部分进行开发。

伊莎贝拉油田位于联邦水域,卡西诺油田西南方向。Amplitude公司持有VIC/L24油田50%的权益并拥有运营权,OG Energy公司持有剩余的50%权益。

Amplitude sidetrack intersects gas pay at Isabella offshore Victoria

Amplitude Energy reached total depth on the ST-1 sidetrack at the Isabella prospect in permit VIC/L24 in the offshore Otway Basin, Victoria, intersecting gas-bearing sands in the primary Waarre C reservoir target.

The 8½-in. hole section penetrated the Waarre C at 1,738 m TVDSS and reached planned total depth of 1,788 m TVDSS. Preliminary drilling and logging-while-drilling data recorded elevated gas readings coincident with increased resistivity, consistent with probable hydrocarbons.

Wireline logging to acquire pressure and sample data is scheduled in the coming days to support resource estimates and gas composition analysis. Following evaluation, the company will decide whether to complete ST-1 with a subsea tree. If completed, the well will be flow tested and suspended for potential development as part of the ECSP.

Isabella is located southwest of the Casino field in Commonwealth waters. Amplitude holds a 50% interest and operatorship in VIC/L24, with O.G. Energy holding the remaining 50%.
