据Oil & Gas Journal网站9月20日报道 日本Inpex公司已向国家海洋石油安全与环境管理局提交了其在澳大利亚近海Ichthys气田二期钻探活动的环境计划。

该项目位于布劳斯盆地生产许可证WA-50-L中，包括在Ichthys油田的12-15口开发井的钻探、竣工和回流。

钻探将使用半潜式移动式海上钻机进行，该钻机将锚定在海床上，并使用动态定位设备。

在项目期间，可使用其他船舶进行其他与油井相关的活动。

钻井计划于2020年上半年开始，并持续5年。

这些井将在235-275米深的水中进行钻探。最近的主要城镇位于金伯利海岸的德比，距离许可证南部边界约390公里。

Inpex已经批准了12-15个钻井中心多达50口井。

最初的开发井在2014-18年期间钻探，油田于2018年7月首次投产，通过海底管道将天然气输送至达尔文的一家液化天然气工厂，并从停泊在油田附近的一艘浮式生产、储存和卸载船将凝析油直接推向市场。

Inpex submits Ichthys Phase 2 drilling plan

Inpex Corp. of Japan has submitted its environmental plan for the Ichthys gas field Phase 2 drilling campaign offshore Australia to the National Offshore Petroleum Safety and Environmental Management Authority.

The program, in Browse basin production licence WA-50-L, will comprise the drilling, completion, and flow back of 12-15 development wells in Ichthys field.

Drilling will be done using a semisubmersible mobile offshore rig, which will be anchored to the seabed and use dynamic positioning equipment.

Other vessels may be used to undertake additional well-related activities during the program.

Drilling is scheduled to begin during the first half of 2020 and continue for up to 5 years.

The wells will be drilled in 235-275 m of water. The closest major town is Derby on the Kimberley coast about 390 km south of the permit’s southern boundary.

Inpex has approval granted for as many as 50 wells across 12-15 drill centers.

The initial development wells were drilled during 2014-18 and the field first came on stream in July 2018 sending gas via subsea pipeline to an LNG plant in Darwin and condensate direct to market from a floating production, storage, and offloading vessel moored near the field.
