Australia’s Vintage delays Odin-2 well completion due to heavy rainfall

Sydney-listed Vintage Energy announced on July 16 that the commencement of the Odin-2 well completion, along with work at Odin-1 and Vali-2, has been delayed due to heavy rainfall in the region over the past fortnight, which has prevented road access.

In early June, Vintage stated that the Odin-2 appraisal well in the Odin gas field in the South Australian Cooper basin would be cased and suspended for future gas production. The well, drilled to appraise the eastern flank of the Odin gas field, encountered gas pay in the Toolachee, Epsilon, and Patchawarra formations—the primary targets.

“At this stage, it is not clear when conditions will dry out sufficiently to enable restoration of road access to the Odin-Vali region,” the company said. Conditions are being assessed on an ongoing basis, with a helicopter survey planned in the coming days. The completion of Odin-2 and production optimisation work planned for Odin-1 and Vali-2 are now expected to commence in August, rather than July as previously advised, with a commensurate impact on schedules.

The lack of access to the Odin gas field has also prevented the restoration of production from Odin-1, which halted on July 2 due to a shut-in requiring a manual restart. Operator access to Odin-1 is expected to occur in the coming days, Vintage added.

The Odin gas field is currently undergoing production appraisal, with gas being supplied to Pelican Point Power, a joint venture of Engie Australia and Mitsui, under a long-term contract extending to December 2026.

Subject to joint venture approval and the scheduling and execution of field work, gas from Odin-2 could commence supply within the current winter.

Odin is the second new gas field brought into supply by Vintage and the joint venture, following the connection of the Vali gas field in Queensland in February 2023. Gas from Vali and Odin is processed at the Moomba processing facility. Both fields have matching joint venture ownership.

Odin-1 commenced production appraisal in September 2023, with gas supplied to Pelican Point Power, a joint venture of Engie and Mitsui, under a long-term contract extending to December 2026.

Vintage is the operator with 50% interest. Metgasco and Bridgeport own 25% each of the project.
