Origin Energy Resources Limited (Origin) is proposing to undertake the Crowes Foot three-dimensional (30) marine seismic survey (herein referred to as the 'survey') in the Otway Basin off southwest Victoria in exploration permits Vic/P69 and Vic/P43. The survey will predominantly be undertaken within Vic/P69 but will ingress Vic/P43 in order to produce seamless data coverage with existing seismic surveys.
 
The full fold coverage area for the survey (the 'acquisition area') will cover up to approximately 930 square kilometres (km2) in water depths ranging from 40 metres (m) to 90 m. Surrounding the acquisition area is an 'operational area', used for conducting operations ancillary to achieving coverage within the acquisition area.
 
At its nearest boundaries, the acquisition area for the survey is located approximately 6.3 km (3.3 nm) south of Moonlight Head, Victoria and 66.8 km (36.1 nm) northwest of the northern tip of King Island, Tasmania.
 
The survey is expected to take place over approximately six weeks during the period 1st October to 31st January, 2015/16 or 2016/17. Exact timing is contingent on receipt of environmental approvals, confirmation of contractor resources and fair sea state conditions suitable for marine seismic acquisition.
 
The survey proposed by Origin is a typical30 survey similar to most others conducted in Australian marine waters (in terms of technical methods and procedures). No unique or unusual equipment or operations are proposed.
