The Artisan 1 exploration well was spudded by the Diamond Offshore Ocean Onyx rig on 23 February, approximately 30 km offshore Victoria, and marks the start of Beach’s offshore drilling campaign.
The well was drilled to a total depth of 2205 m measured depth (MD) and penetrated the primary Upper Waarre Formation at 1921 m MD, approximately 92 m high to prognosis. The well intersected a gross gas column of 69.5 m in the Upper Waarre Formation, including 62.9 m of net gas pay, with a gaswater contact intersected at 1990 m MD.
A gross gas column of 20.9 m was also intersected in the secondary target of the Flaxman Formation from 1902.8 m MD, with net gas pay of 4.6 m.
The well is being cased and suspended as a future producer with an opportunity to tie into the offshore pipeline, currently delivering gas from the offshore Thylacine and Geographe fields to the Otway Gas Plant, at a later date.
Beach Energy Managing Director and CEO, Matt Kay, said the result, which follows the success of the Enterprise well in November 2020, provides Beach 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.”
The rig will 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 FY22.
