Beach Hits Gas in First Victorian Otway Campaign Well

Australian oil and gas company Beach Energy has made a gas discovery at Enterprise 1 in licence VIC/P42(V) in the nearshore Victorian Otway Basin, Australia. This is the company’s first exploration well in the Victorian Otway program.

Beach is the operator of the licence with a 60 per cent interest and O.G. Energy is its partner with the remaining 40 per cent interest.

Beach Energy said on Tuesday that the Enterprise 1 was spud from an onshore location, 3.5 km from Port Campbell and 8 km from the Otway Gas Plant.

The well was drilled directionally using an extended reach drilling (ERD) approach to deliver a well with a 3.2-kilometre step-out, to target a location within the offshore permit VIC/P42(V).

Beach said that the well was successfully drilled to a total depth of 4,974 metres measured depth (MD) and encountered the primary reservoir target of the Upper Waarre Formation 89 metres high to prognosis at a depth of 4,594m (MD) (2,052 metres vertical depth subsea).

The well intersected 146 metres of gas column in the Upper Waarre Formation, including 115 metres of net gas pay with no gas-water contact identified. Sampling indicates a gas composition with 10% CO2 by volume.

The forward plan is to case and suspend the well as a future producer. A well test will confirm well productivity and provide data for the proposed pipeline to the Otway Gas Plant. Detailed engineering work and regulatory approvals process for the pipeline is already underway.

Estimates of potential resource size are not yet defined, with the formation evaluation program still in progress. Beach’s preliminary assessment is that key reservoir parameters are interpreted to be in-line with pre-drill expectations.

Beach Energy Managing Director and CEO, Matt Kay, said: “To have our first exploration well in the Victorian Otway program deliver a successful result is an excellent outcome for the business”.

“This success enhances our plans to develop more supplies for the East Coast gas market. The Enterprise result also de-risks other nearby prospects, warranting their evaluation as potential future drilling candidates”.

“Our focus now moves to the upcoming offshore Victorian Otway Basin drilling campaign, which is due to commence in the March 2021 quarter. The first well drilled will be the Artisan 1 exploration well, followed by development wells in the Geographe and Thylacine fields”.

As reported earlier, Beach is preparing to drill the Artisan offshore exploration well, which has been delayed due to the Covid-19 pandemic.

Drilling is now anticipated to occur within the period from 3Q 2020 to the end of 2021.
