Description

Lattice Energy Limited (Lattice), who are wholly owned by Beach Energy Limited (Beach), proposes to drill a single exploration well (with the option to suspend and develop pending reservoir analysis) in Commonwealth waters of the Otway Basin approximately 32 km off Victoria’s south-west coast.
The Artisan-1 well is proposed to be drilled by a semi-submersible mobile offshore drilling unit (MODU). The Ocean Onyx is currently proposed to undertake this drilling activity. The Ocean Onyx is a conventionally moored, non-self-propelled, column-stabilised semi-submersible MODU owned and operated by the Diamond Offshore General Company (Diamond Offshore).
The proposed Artisan-1 well location is at a water depth of approximately 71 m. The operational area for the drilling program has been defined as a 2 km radius around the well whilst the MODU is moored on location. The 2 km radius encompasses both the outer extent of mooring equipment on the seabed, and the 500 m rig safety exclusion zone (RSEZ).
The drilling activity is planned to commence in Q4 2019 or Q1 2020 with drilling expected to take approximately 35 to 55 days, depending on the final work program and potential operational delays. The Artisan-1 well maybe suspended for future production if commercial quantities of hydrocarbons are discovered. In this eventuality, the well will be suspended in accordance with the Well Operations Management Plan (WOMP) and the wellhead will be left in place to facilitate future operations. Any potential future production drilling of Artisan-1 well will be addressed under a separate Environment Plan (EP). Drilling and support operations will be conducted on a 24-hour basis for the duration of the program.
The activities included in this EP are: Drilling activities including MODU operations and any pre-lay anchoring operations; routine support activities such as vessel operations, helicopter operations and ROV operations; and emergency response activities.
