Beach Energy, licence holders of PEL 186 contracted Trace Energy Services to record the Nunga Mia 3D Seismic survey during April 2012. The primary objective of this survey was to define leads in the Robe Trough area of the Otway Basin with a particular focus on the Lower Crayfish group of sediments. The survey grid was located just to the east of the township of Robe and covered an area of approximately 70km2. Acquisition parameters were generally Group Interval of 50 meters and a VP Interval of 50 meters for maximum CDP coverage of 72 fold stack. Source and receiver lines were spaced 350 apart. No upholes were recorded during this survey. All data was processed Dayboro Geophysical in Queensland. Although a number of small structures were identified, they were deemed too small to follow up. A combination of poor resolution and lack of continuity in conjunction with intense faulting produced areas of low confidence with mapping particularly at some of the shallower horizons but correlation and confidence was improved at the Crayfish and Windamere Formation horizons.
