Beach discovers gas at Otway Basin well

Walyering reaches final depth after 13 days

Beach Energy has confirmed a gas discovery at the Artisan 1 joint venture well with O.G. Energy in licence VIC/P43 offshore Victoria in the Otway Basin.

The Artisan 1 exploration well 30km offshore Victoria was spudded by the Diamond Offshore Ocean Onyx Rig last month, marking the beginning of the company’s offshore drilling campaign.

The well was drilled to a total depth of 2205m measured depth (MD) and penetrated the primary Upper Waarre Formation at 1921m MD, 92m high to prognosis.

It intersected a gross gas column of 69.5m in the Upper Waarre Formation, including 62.9m of net gas pay, with a gaswater contact intersected at 1990m MD.

A gross gas column of 20.9m was also intersected in the secondary target of the Flaxman Formation from 1902.8m MD, with net gas pay of 4.6m.

The well is now being cased and suspended as a future producer with an opportunity to tie into the offshore pipeline, which currently delivers gas from the offshore Thylacine and Geographe fields to the Otway Gas Plant.

Beach managing director and chief executive officer Matt Kay said the result, which follows the success of the Enterprise well in November 2020, provided the company with further optionality across its Otway Basin portfolio.

“Beginning our Otway campaign with two exploration successes is a good result for Beach,” Kay said.

“While the Artisan discovery is at the lower end of pre-drill expectations, it is being cased as a future producer. Drilling operations have gone to plan and I want to commend the teams working on the Ocean Onyx for the successful start to the campaign.”

In addition, the rig will now move to the Geographe field after the casing operations and commence the first of two in-field development wells before moving to the Thylacine field for an additional four in-field wells.

First gas from the new Geographe wells is expected to commence in the 2022 financial year.
