Vali-1天然气探井顺利钻探

据油田技术1月7日报道，Metgasco有限公司董事会表示，Vintage Energy公司运营的Vali-1 ST1天然气探井正在澳大利亚Patchawarra地层中钻探，钻探深度为3059米。

除了上周报道的Nappamerri和Toolachee地层的天然气发现外，Patchawarra地层也观察到了天然气迹象。虽然这些天然气发现令人鼓舞，但在获得具体勘探数据之前，很难确定它们的重要性。这些迹象是除了在较浅的Westbourne和Birkhead地层已经报道的石油发现之外的。

由于岩石十分坚硬，钻头需要进行多次更换，导致钻井速度变慢。因此，可能要到本周晚些时候或下周初才能到达目标底层，之后将进行电缆测井。

Vali-1 ST1主要目标为Patchawarra地层，Toolachee地层为次要目标。在Vali-1 ST1的15至40公里半径范围内，以及开采了超过6000亿立方英尺的天然气。

Drilling align="justify">The Board of Metgasco Ltd has advised that the Vali-1 ST1 gas exploration well operated by Vintage Energy is being drilled through the Patchawarra Formation in Australia at a measured depth of 3059 m.

In addition to the shows reported last week in the Nappamerri and Toolachee Formations, gas shows have been observed in the Patchawarra Formation. While these gas shows are encouraging, it is difficult to define how significant they will be until logs are acquired. These shows are in addition to the oil shows already reported in the shallower Westbourne and Birkhead formations.

Drilling has been slow due to hard lithology which has necessitated a number of bit changes. As a result of this, it is likely that TD will not be reached until late this week/early next week, after which wireline logs will be acquired.

The Vali-1 ST1 primary target is in sandstones of the Patchawarra Formation, with the Toolachee Formation being a secondary objective. With over 600 billion ft3 of gas produced from fields within a 15 to 40 km radius of the proposed Vali-1 ST1.
