These blocks were awarded to GTO Ltd (30%) and COOTS (50%) in the recent UK 26th Round announcement – Oct 2010. These blocks have been awarded on a promote basis. The blocks are located on the south west margin of the Central North Sea basin towards the Mid North Sea High. The play that is being worked is the Rotliegendes Sandstone, sealed by thick Zechstein evaporites and sourced from the underlying Carboniferous. The reservoir and seal elements are proven in wells to the north, however the source is circumstantial at present – gas chimneys etc. Both structural and a huge stratigraphic trap have been identified on vintage 2D seismic augmented with 2007 TGS spec data.
