Wonnich Deep-1 Encounters Gas at Secondary Objective

Tap Oil reports that the Wonnich Deep-1 well is still suspended after the rig was evacuated for Tropical Cyclone George. Before the evacuation the well had reached 4,100 meters measured depth. After re-manning, the well is planned to drill to a total depth of around 5,200m measured depth.

Wonnich Deep-1 is located in production license TL/8 offshore Australia and is being drilling from the existing Wonnich Platform.

The secondary target Flag reservoir was intersected and logs indicate an un-swept 28.5m gas column overlying a 3.5m oil column.

The un-swept gas zone at the Flag sandstone level in Wonnich Deep-1 is a positive result and is better than expectations inferred from production data. It is possible that the gas in this part of the field is in a separate compartment from the gas currently being accessed by the Wonnich-1 production well. The gas identified in the Wonnich Deep-1 well will have a positive effect on reserves estimates for the Wonnich producing field.

The primary objective of the well is to test the Upper Jurassic Dupuy sandstone which is a proven reservoir in the basin. With delays due to cyclones it is anticipated that results from this level will be available in 10-14 days.
