GeoPartners, in partnership with MAGE, Seabird Exploration and DownUnder GeoSolutions, have acquired a new regional multiclient 2D (MC2D) seismic survey entitled North Celtic Sea 2015.
This Ireland/UK cross-border project is located mostly in the Irish North Celtic Sea and St. Georges Channel.
Acquisition commenced in early July using the MAGE vessel Nikolay Trubyatchinsky (formerly Polar Explorer) - a total survey size of up to 6000km of long offset broadband data is planned.
This project aims to provide the high quality, extensive, regional data-set which is so lacking in this geophysically challenging area.
With these challenges in mind the acquisition and processing parameters have been carefully chosen. Dip lines have been planned to complement vintage data and a strike-line orientation has been designed to minimize side-swipe from faults.
This area of the Celtic Sea and UK Western Approaches is underexplored at pre-Cretaceous levels and shows promise, especially within the Jurassic and Triassic sequences, which few wells have penetrated. There is a proven Liassic source rock and potential reservoirs include the Triassic Sherwood sandstone and Jurassic limestone and sandstone. Locally, the carboniferous could provide a gas source from coal measures and a potential oil source from the Bowland shale, as in the Morecambe Bay Hamilton field.
The survey provides well ties to most of the wells in the survey area, including key wells:
Broadband processing and imaging will be carried out by DownUnder GeoSolutions utilizing their deghosting solution, DUG Broad. Industry funding supports the MC2D survey and processing will be completed in January 2016.
