Dove Energy Ltd has a 50% share in Blocks 43/14b and 43/15b with PA Resources (formerly Scotsdale Petroleum), the Operator. The blocks are located on the northern margin of the Southern Gas basin, in 80 to 175ft of water. They cover an area of 288 sq km and are on trend with the nearby Cavendish and other Carboniferous reservoired gasfields.

The area is on the southern margin of the Mid North Sea High, where post-Carboniferous sediments thin northwards onto this stable platform and progressively older Carboniferous sediments subcrop the pre-Permian unconformity. Preserved Upper Carboniferous Westphalian sediments are thought to be preserved in the area of the blocks.

The blocks lie between the Esmond, Forbes and Gordon Fields, where gas is reservoired in shallow Triassic Bunter sandstones. Many of the unsuccessful wells were aimed at this play without testing the underlying Carboniferous section.

More importantly the Blocks lie immediately northeast of the Cavendish Gas Field. Here, the trap is an NW - SE trending tilted fault block, sealed by the Permian Silverpit shales. The sandstone reservoirs are Upper Carboniferous Westphalian 'A' and Namurian intervals (Millstone Grit and Caister Coal Formations). The gas source is shales and coals in the same Carboniferous sequence.

A series of major regional structural trends involving Carboniferous strata set up a series of inversions, tilted fault blocks and uplifts on a NW - SE orientation. Carboniferous sands subcropping to the pre-Permian unconformity may well have had their reservoir characteristics enhanced by sub-areal weathering at that time.

The 2D seismic data available pre-award, although not of optimum quality, confirmed the two structural prospects. This was followed up with the acquisition of 3D seismic at the end of 2008. This will be available for interpretation during the second quarter of 2009.
