WEST PERTH, Australia– Searcher Seismic has completed the Laurabada Ultracube 3D reprocessing project offshore Papua New Guinea.
The project entailed the reprocessing of two open-file 3D datasets with a modern broadband de-ghosting and pre-stack depth migration sequence. The Ultracube is split into two cubes: The Eastern cube is near-shore, shallow water while the Western cube is deepwater in the Gulf of Papua.
Joshua Thorp, geoscience manager for Searcher Seismic, said there has been data quality uplift from the reprocessing of the legacy data which has revealed new potential in the Gulf of Papua.
“Source and receiver deghosting was applied in the reprocessing which significantly improves the low frequency content. For Laurabada East, this helps with the imaging below the fold belt as that is quite dispersive and attenuative with the seismic source. Similarly, on Laurabada West, there is multiple large carbonate bodies that are highly absorptive which is only penetrated by the low frequency signal…”
The Laurabada West Ultracube 3D reprocessing survey comprises of ~770 sq km (297 sq mi) while the Laurabada East Ultracube 3D reprocessing survey covers ~1,020 sq km (394 sq mi).
