- 100% exploration/appraisal success achieved from three well drilling campaign in Cooper Basin
- Vali-3 wireline logging completed, confirming gas pay in line with pre-drill expectations
- Vali-3 cased for future production along with Vali-1 ST1, Vali-2 & Odin-1
As previously advised, the Vali-3 well reached total depth at 3,186 metres on Monday, 28 June 2021.The wireline logging evaluation was successfully completed and the well cased and suspended. The SLR184 rig, used to drill the three successful wells from this recently completed Cooper Basin campaign, was released at 7 pm CST last night. Metgasco would like to thank operator Vintage and all contractors involved with the drilling, casing and assessment of the Vali-2, Vali-3 and Odin-1 (PRL 211) wells. The work undertaken in this campaign was industry best practice and completed in a safe and timely manner.
The main objective of the Vali-3 well was achieved following the intersection of the Patchawarra Formation in line with the pre-drill interpretation of the Vali structure. Evaluation of the recently completed wireline logging program has confirmed interpreted gas pay within the Patchawarra, consistent with pre-drill expectations and the location of the well within the field.
During drilling, further gas shows were observed in the lower Nappamerri Group, Toolachee and Epsilon formations, and the Tirrawarra Sandstone. Samples collected from the Nappamerri Group and Toolachee Formation during the evaluation program will be analysed to determine whether gas pay can be interpreted in any of the sands in these zones. The results will be advised over the coming weeks once complete.
Oil shows were observed through the late Cretaceous, Jurassic and Triassic sediments, as well as the uppermost Permian aged Toolachee Formation. Similar shows were encountered in both the Vali-1ST! and Vali-2 wells and are a major positive for oil potential within the ATP 2021 permit, where more than 12 oil leads have been identified. Despite there being no mappable Jurassic structural closure around the three Vali wells, a particularly good oil show was observed within the McKinlay Member in Vali-3 and sampling recovered water, likely mud filtrate, with hydrocarbon odour and blue-white fluorescence. This suggests that oil has migrated through this area and increases the prospectivity of the Jurassic structural closures nearby.
The Joint Venture now has three cased wells in the Vali Field available for future production. The well evaluation data from Vali-2 and Vali-3 will be provided to ERCE to provide an independent gas reserve assessment in the coming weeks. Further results of the well evaluation and impact on field reserves will be communicated as they come to hand. The Joint venture is excited by the continued success from its drilling program and look forward to progressing plans for production from the emerging Cooper Eromanga production hub in ATP2021 and PRL211 .
