SEISMIC SURVEYING 


equipment (up to 6300 cu in) and is said by Searcher to be one of the best equipped 2D seismic vessels available for this project. Te seismic data processing will be


undertaken in Perth, Western Australia, and will provide a consistent regional dataset that also ties the most relevant well information. A full suite of additional products will be generated during the processing sequence and will allow further work such as AVO studies, inversion and basin modelling.


Intensified exploration Te Browse Basin has received intensified exploration in recent years after a sporadic exploration history. Several large gas fields (> 5TCF) has been discovered within the basin and with these discoveries has seen the push to commercialise them via LNG facilities. Outboard potential of this basin has now also been successfully tested. No comprehensive regional well tie survey


has been acquired for at least 10 years in the Browse and tying these new discoveries is a key objective of the Vampire 2D survey. Back in the Northern Hemisphere,


CGGVeritas has completed acquisition of the first phase of a new 3D programme in and around the Quad 44 region of the Southern North Sea with GeoPartners. Te Lodestone


survey complements the existing high-quality, recent vintage Cornerstone and Runestone surveys located in the Central and Northern North Sea Basins. Te Lodestone survey provides state-of-


the-art long-offset data using Sentinel solid streamers which are essential when imaging the variable-quality and compartmentalised Permian and Carboniferous reservoirs lying


beneath complex salt bodies, using high-end processing techniques. Luc Schlumberger, executive vice


president, multi-client and new ventures, CGGVeritas, said: “Given the increasing interest of the industry in the Southern North Sea, we believe Lodestone will offer a high- quality resource to unlock the full potential of this prolific basin.” 
