Acquisition of the Bilby 2D seismic survey begins offshore WA

Oilfield Technology,

Searcher Seismic, in co-operation with BGP, has announced that the Bilby Non-Exclusive 2D seismic survey acquisition has commenced.

Bilby 2D seismic survey, Western Australia

The Bilby 2D seismic survey in the Bedout Sub-basin and Broome Platform, Western Australia comprises of approximately 12 300 km of 2D long-offset, high resolution broadband data over 2x4, 4x8 and 8x8 km grids.

The survey has been designed to provide a grid of modern, high quality data to help identify prospective structural and stratigraphic trends that can be used for regional evaluations and future detailed seismic survey design.

Substantial potential in this area

Rachel Masters, Global Sales Manager for Searcher, said last year’s Phoenix South-1 discovery demonstrates a working oil petroleum system exists in the area and caused a wholesale change in thinking regarding the prospectivity of the area.

“Substantial potential appears to exist not only in and around the Phoenix South area, but up-dip on the flanks of the basin, where the results of Keraudren-1 demonstrate significantly better quality reservoirs exist within the Triassic sediments.

“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,” Ms Masters added.

Project specifics

The survey is being acquired by the BGP explorer using high-end Sercel Sentinel Solid Streamer technology, Bolt Source equipment and continuous recording.

The seismic data processing will be conducted by DownUnder GeoSolutions, Perth, and deliverables will initially be provided through a comprehensive DUG Broad PSTM flow to produce a high quality, yet timely delivery of final data which is expected from June 2015.

Offshore Canning Area Prospectivity Study

In addition to the Bilby 2D survey, Searcher in conjunction with Insight Petroleum has recently completed an Offshore Canning Area Prospectivity Study.

The Prospectivity Study is available now and provides timely and strategic information to assist companies to understand the implications of the recent Phoenix South-1 discovery and the prospectivity of the Bedout, Rowley and Oobagooma Sub-basins and adjacent platform areas.

Searcher is also undertaking the Roebuck Super-Tie™, a regional grid comprising over 5000 km of reprocessed PSTM data. Data will be available in May 2015.
