Survey

Searcher Seismic and BGP have begun the Bilby Non-Exclusive 2D seismic survey in the Bedout Sub-basin and Broome Platform, Western Australia.

Consisting of approximately 12,300km of 2D long-offset, high resolution broadband data over 2km x 4km, 4km x 8km and 8km x 8km grids, the survey has been designed to provide a grid of modern, high quality data.

It will help in finding prospective structural and stratigraphic trends for regional evaluations and future detailed seismic survey design.

Searcher Seismic global sales manager Rachel Masters said: "Last year’s Phoenix South-1 discovery demonstrated a working oil petroleum system exists in the area and caused a wholesale change in thinking regarding the prospectivity of the area."

Using Sercel Sentinel Solid Streamer technology, Bolt Source equipment and continuous recording, the survey will be undertaken by the BGP explorer vessel, while Perth’s DownUnder GeoSolutions will perform the seismic data processing.

"Last year’s Phoenix South-1 discovery demonstrated a working oil petroleum system exists in the area and caused a wholesale change in thinking regarding the prospectivity of the area."

Deliverables will initially be provided via a DUG Broad PSTM flow to produce final data, which is anticipated from June.

Masters said: "The results also highlight the potential for oil to migrate up onto the adjacent Broome Platform into accumulations analogous to the Stag, Gwydion and Cornea fields elsewhere in the region."

Apart from the the Bilby 2D survey, Searcher has recently completed an Offshore Canning Area Prospectivity Study in partnership with Insight Petroleum.

The company is also undertaking the Roebuck Super-Tie, a regional grid comprising more than 5,000km of reprocessed PSTM data.
