Drilling ongoing at Vali-1 gas exploration well

Published by , Editor

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. These reservoirs have been proven as producing reservoirs on the southern flank of the Nappamerri Trough, with over 600 billion ft3 of gas produced from fields within a 15 to 40 km radius of the proposed Vali-1 ST1.
