Big Buzz 3D Reprocessing

Phase Two

Buzzing with Excitement – Advanced seismic data for North Sea Exploration

Following the success of the initial Phase I Big Buzz Reprocessing, Searcher have extended the project into a second phase. The initial Reprocessing project saw the integrating reprocessing of four 3D surveys covering 1,560 km2 over the South Halibut Horst in the North Sea, seamlessly merging them into one extended volume with a high-end processing workflow incorporating Full Waveform Inversion (FWI) and Pre-Stack Depth Migration (PSDM).  

Phase 2 extends this cube by incorporating an additional two volumes to the north, adding approximately 690 km2 of data to bring the total reprocessed volume to 2,250 km2. Reprocessing provides a significant advancement in imaging over the original vintage processing, allowing for improved confidence and reliable geological interpretation to support infrastructure-led exploration (ILX) agendas, which provides a model for explorers who prioritise prospects for rapid development.
