Vintage Energy Ltd., Adelaide, has seen continued success in adjoining Cooper basin permits across the South Australian and Queensland borders.

The Vali-3 appraisal well in Queensland permit ATP 2021 is drilling ahead at 2,774 m towards its primary objective in the Permian age Patchawarra formation having already recorded gas shows in the overlying mid-Nappamerri formation and gas with minor oil shows in the Toolachee formation.

Vintage said it is unlikely the Toolachee oil will be recoverable, but it is an encouraging sign for other leads in the area. It is possible for oil migration to shallower Jurassic (Eromanga basin) prospects in the permit which is analogous to the Cooper basin Western Flank fairway in South Australia, the company said.

Vali-3 is intended to appraise the extent of the deeper Patchawarra gas accumulation discovered in Vali-1 ST1 and confirmed recently in Vali-2. Vintage expects to reach total depth and evaluate the Patchawarra in the coming days.

Additionally, the company has received a gas composition analysis for the Odin-1 discovery in adjoining South Australian retention lease PRL 211.

Vintage estimates that 172.5 m of net gas pay exists within the various sections of the well made up of 37 m in the Toolachee, 4.5 m in the Epsilon, 126 m in the Patchawarra, and 5 m in the Tirrawarra.

The richest hydrocarbon content was recorded in a gas sample from the Toolachee: 79% methane, 3% ethane, 1% other, and 17% inerts.

The Epsilon samples recorded 75% methane, 2% ethane, and 23% inerts, values similar to Patchawarra formation samples from previous wells.

The data will be independently evaluated to provide resource numbers for the Odin field along with a reserve certification. Odin is a fault-bounded Patchawarra formation closure up-dip from 1987 wildcat Strathmount-1 that found what was then considered non-commercial gas.

Vintage is operator for both permits. Interest holders in ATP 2021 are Vintage 50%, Metgasco Ltd. 25%, and Bridgeport (Cooper Basin) Pty Ltd. 25%. Interest holders in PRL 211 are Vintage 42.5%, Metgasco 21.5%, Bridgeport 21.25%, and Impress (Cooper Basin) Pty Ltd. 15%
