Danish explorer Dong E&P has made a hydrocarbon discovery with a wildcat drilled at its Trym South prospect in the southern North Sea off Norway.

The 3/7-8 S well struck oil and gas in a gross column of 159 metres in the Middle Jurassic Sandnes and Bryne formations after being drilled by jack-up Maersk Giant to a vertical depth of 3688 metres in a water depth of 65 metres about two kilometres south of the producing Trym field.

However, a secondary target in the Maureen formation proved dry.

The find has a preliminary reserves estimate of 6.29 million and 12.6 million barrels of oil equivalent, according to the Norwegian Petroleum Directorate.

The well, drilled in Dong-operated production licence 147, will now be permanently plugged and abandoned.

The rig is now set to drill another wildcat for the Danish player at the Musling prospect in neighbouring PL289, also operated by Dong, located north-west of the Trym field.
