Perenco UK discovers gas at Ravenspurn South

Perenco UK (PUK) made a near-field discovery on Ravenspurn South (RS) in well C06, proving gas in a previously undrilled fault block downdip of the currently producing RS field in the Southern North Sea.

RS C06 found a 90 m section of fully gas-bearing Lower Leman sandstone, Rotliegend formation, with reservoir properties in line with nearby RS producers. The initial rate, forecast for January 2024, is expected to deliver a base case of about 12 MMscfd (2,000 boe/d), bringing 21 bscf (3.5 MMboe) incremental reserves after 30 years.

After completion with the Valaris-247 rig, the well will be stimulated with support from the Petrodec ERDA jack-up barge. A well test will enable effective monitoring and clean-up before connecting the gas produced from this new well via the Cleeton Hub into Perenco’s Dimlington terminal.

This is the third well in Perenco UK’s Southern North Sea (SNS) 2023 drilling campaign using the Valaris-247 rig, and follows the successful drilling of Ravenspurn North sidetracks, D15 and D16, currently producing 30 MMscfd.

Perenco UK owns 100% of Ravenspurn South.
