Siccar had hoped that the well, if successful, would be large enough to form a new gas-hub development similar to the Total-operated Laggan-Tormore fields which have been developed with subsea infrastructure with pipelines to the Shetland Gas Plant.  The prospect had been thought to contain 1-3 trillion cubic feet of recoverable gas.

However, the company on Friday said the well was drilled to a depth of 4005 meters below sea level in a water depth of 1452 meters, and the target interval contained 44m of siltstone and claystone with gas shows but the well did not encounter reservoir quality sandstone. As a result, the well was plugged and abandoned.

Jonathan Roger, CEO of Siccar Point commented: “We look forward to continuing to explore the area, which we believe still has prospectivity, and will be looking at participating in forthcoming UK licensing rounds in order to do that.”

The Lyon well is located in the P1854 block approximately 125 kilometers northwest of the Shetland Islands. The block is owned by the partnership between Siccar Point (33.34%, operator) and Ineos (66.66%). The well – spud in mid-May -was drilled using the Ocean GreatWhite – the world’s largest semi-submersible drilling rig.
