GeoStreamer Cracks the Weather Window

Friday, Feb 20, 2009

On January 12th, PGS completed a MultiClient 2D GeoStreamer survey in the Southern North Sea. Despite the climate and the weather, data quality is first class and bodes well for future winter acquisition using this technology.

Deep below the surface, GeoStreamer records crystal clear data, unperturbed by winter waves. No survey shows this better than the recent MultiClient 2D survey MNSG2009. Recorded in the middle of a typical North Sea winter, the results are extraordinary. At 15+ meters depth, the recording cable is undisturbed by the weather and the signal to noise ratio is first class. Could this mark the end of time-sharing in a crowded summer seismic season?

"Once again, we see that GeoStreamer produces excellent results in circumstances that would render conventional streamer operations unfeasible," says Guillaume Cambois, Senior Advisor in PGS Data Procession & Technology. "The acquisition quality is fantastic and we look forward to seeing the fully processed data." 

MNSG2009 conveniently closes a gap in PGS MC3D MegaSurvey coverage, linking the central North Sea and Southern North Sea MegaSurveys and straddling the UK/Netherlands offshore boundary. The UK Mid North Sea High still remains something of an underexplored frontier area, where the Paleozoic geology and its hydrocarbon petroleum potential are not yet fully understood.
 
MNSG2009 was designed to provide some key regional lines as well as tying a large number of wells and investigating firmly planned and possible drilling locations. Based on previous experience with GeoStreamer acquisition, improvements in penetration and resolution should provide a better regional understanding of the deep geology and petroleum prospectivity of this province.

A significant part of the grid in the west is focused on The Breagh Carboniferous Gas discovery, which has effectively confirmed a new hydrocarbon province and is attracting industry interest. The new 2D data should help to answer some remaining questions about the hydrocarbon source kitchen, migration routes and extent of this province in good time for the forthcoming UKCS 26th Licensing Round.
