Vali-3 net gas exceeds expectations

Vintage Energy

Vintage Energy has reached total depth at the Vali-3 well, achieving its main objective of intersecting the Patchawarra formation at the Queensland project.

During drilling, gas shows were observed in the lower Nappamerri Group, Toolachee, Epsilon and Patchawarra formations, and the Tirrawarra Sandstone.

Managing director Neil Gibbins said the recent three well drilling campaign, which came after the first exploration success at Vali-1 ST1, included the two Vali appraisal wells and the discovery of gas in the Odin prospect.

“These wells have delivered the necessary gas fields and volumes for us to move forward with commercialising the Southern Flank province,” he said.

“What is pleasantly surprising is the increase in reservoir quality sand, and resultant net pay, in the Patchawarra formation for both Vali-2 and Vali-3 when compered with Vali-1 ST1.”

Material increases in reservoir sands content were encountered through the Patchawarra Formation in both Vali-2 and Valie 3.

The analysis by the Vintage team of wireline logging data estimates a total of 165m of conventional and lower deliverability net gas pay within the Patchawarra formation in Vali-3.

Thirteen metres of conventional and lower deliverability net gas pay was also identified in the deeper Tirrawarra Sandstone.

Gibbins said that discussions are well advanced with a number of interested parties regarding pre-sales of gas and potential flow-line infrastructure funding, to connect the Vali Field to the Moomba gas gathering network.

“Such agreements will be carefully structured to ensure the Vali project is progressed in the most capital efficient manner and will be announced to the market once terms are finalised between the relevant parties and the joint venture,” he said.

The joint venture has now cased three wells in the Vali field available for future production.

Following the data being viewed form the Vali wells, it will be sent to ERC Equipoise to update the reserves certification for the Vali field as a whole.
