SEARCHER Seismic and DownUnder GeoSolutions have joined forces to market seismic data acquired during a multi-client seismic project covering a portion of the North West Shelf, off Western Australia.
The data, together known as the Monodon Ultracube, consists of about 14,700 square kilometres of 3D and 2,000 kilometres of 2D reprocessed data in the prospective Northern Carnarvon basin of the North West Shelf, Western Australia.
Incorporating 16 individual 3D surveys and three 2D surveys shot between 1982 and 2004, the package includes the reprocessing from field tapes using a state-of-the-art flow and cutting edge algorithms that include industry leading linear noise removal and regularisation.
They include the Panaeus 1, Panaeus 2 South, Panaeus 2 North, Panaeus 99A, Panaeus 99B, Panaeus 99C, Panaeus 99 East, Panaeus 2000 West, Panaeus 2001 East, Wandoo, Stag, Cash, East Dampier, Demeter and Shelley OBC marine seismic surveys.
The datasets were processed from SEGD field tapes by DownUnder GeoSolutions in their Perth office from April 2011 to January 2012.
Searcher Seismic global sales manager Rachel Masters said the data package has excellent coverage of several areas included in the proposed 2015 Australian acreage release.
“Large scale 3D surveys of this size are invaluable for geological interpretation and basin modelling applications, and we are confident our clients will be able to utilise this data to evaluate the acreage in the area,” she said.
The reprocessed data has been merged prior to anisotropic (TTI) pre-stack depth migration incorporating multi-iteration tomographic model building.
Data from all stages of the processing are available, including image gathers and angle stacks, Searcher said in an announcement.
