introduction to the great australian bight

In October 2013, Chevron Australia (Chevron) acquired two deepwater exploration permits (EPP44 and EPP45) in the Great Australian Bight (the Bight).  Located in Commonwealth marine waters adjacent to South Australia (approximately 200 km south-west of Ceduna and 300 km west of Port Lincoln), the exploration permits span more than 32,000 km2.  Chevron is planning an exploratory drilling program in these permit areas.  Four exploration wells will be drilled in the permit areas over a two year period (two exploration wells drilled in each permit each year).  At the conclusion of the exploration activity the wells will be permanently plugged and abandoned.

Chevron is preparing a Great Australian Bight Exploration Drilling Environment Plan (EP) in accordance with the Offshore Petroleum and Greenhouse Gas Storage (Environment) Regulations 2009 (OPGGS(E) for submission to the National Offshore Petroleum Safety and Environmental Management Authority (NOPSEMA).  The EP covers all drilling-related activities, from arrival of the drill rig into the permit areas, through to demobilisation and exit of the rig from the permit areas.
