GdF Suez has found a new gas resource in the southern U.K. North Sea on the Cepheus prospect.

After drilling the 44/12a-6 Cepheus exploration well, the operator said a gas column was encountered within a Permian Lower Leman sandstone.

Drilling commenced in early March, and the well was deviated northeast from the top hole location in Block 44/12a toward the target location. The site is near the GdF-operated Cygnus Field development where new platforms are being installed.

Drilling at Cepheus, which was operated by GdF partnered by Centrica North Sea Gas and Bayerngas E&P, was carried out with the TSF Monarch rig, which is due to leave the Cepheus well location after plugging and abandoning the hole.
