Overview of activitiesBeach Energy is planning further development of the Otway offshore natural gas reserves within existing Commonwealth offshore exploration permits and production licenses.

Activities will include:

• Seabedassessmentstodeterminethesuitabilityoftheseabedforthedrillingoperationsandinstallationofinfrastructure to connect new production wells to the existing platform or pipeline

• Drillingofoffshoreexplorationandproductionwells,upto9 in total

• Inspectionsandmodificationstoexistingseabedinfrastructure to prepare for the new activities

• Tie-instoconnectnewproductionwellstotheexistingplatform and pipeline

• PlugginganddiscontinuingofoneormorewellsintheGeographeandThylacinefield

Why was this area chosen for gas exploration and development?

Beach Energy holds offshore exploration permitsandisrequiredtocompleteexploration activities within timeframes setbytheCommonwealthNationalOffshorePermitTitlesAdministrator(NOPTA).BeachEnergyalsohasexisting production permits and offshore gas facilities in the area already extractinghydrocarbonsandoperatesagasprocessingplantnearPortCampbellproducingnaturalgasfromthesereservoirs.TheproposedactivitieswillenableongoinggassupplyfortheVictorian market.

What is an Environment Plan and who will assess it?

ThecontentsofanEnvironmentPlanare set out in the Regulations and must include a description of the existing environmentandtheproposedactivity,an evaluation of the impacts and risksassociatedwiththeactivities,environmental performance outcomes andstandards,implementationstrategy,andreportingrequirements.

What is ALARP?

ALARPstandsfor“AsLowAsReasonablyPracticable”.Itisanassessment principle commonly used in the oil and gas industry to assess and reduce potential risks and impacts that cannotbecompletelyeliminated.ForinformationonhowNOPSEMAassessesALARPsee:https://www.nopsema.gov.au/about/our-regulatory-activities/

What does an Oil Pollution Emergency Plan cover?

• Responsearrangementsandcapabilityinplaceformonitoringoil pollution to inform response activities as well as monitoring the effectiveness of these activities

Thesearrangementsarebasedontheworse case spill event associated with the proposed activities to ensure that Beach Energy has the appropriate level ofresponsearrangementandcapability.

Beach Energy is committed to minimising the impact of its activities and will consult with commercial fishers on arrangements to ensure each other’s operationalplansareunderstood,helping to minimise any impacts to fishing activities and to Beach’s offshore development program.

How will you reduce the risk of collision with other vessels?

Themarinevesselsinvolvedintheactivities will operate in accordance withAustralianMaritimeStandardsandensuresafeoperationsby:

• Havingoperationalandnavigationlighting on all vessels

• Maintaininga24-hourshippingradarwatch

• Ensuringvesselshaveacrewtomaintain24-hourvisual,radioandradar watch for other vessels

• Equippingvesselswithnavigationlighting and movements that comply with maritime standards

• Monitoringandmanagingsafetyandexclusion zones

Will the activities affect whales and dolphins?

Will the drilling impact shipwrecks?

How does the drilling rig work?

Beach Energy will use a typical semisubmersibledrillingrigthatisusedinAustralianwaters.Itcanoperateinwatersupto3,000mdeep,drillforgasatupto10,000mdeepandcanaccommodatearound150crew.

Once the drilling rig is in position and anchoredatthewellsite,thedrillingprocess is expected to use four or five stagesofdrilling,startingwitha36-inchdrillhead.Drillingwillthenreducein diameter to consecutively smaller sizes until it reaches the end target depth.
