A report on the Wressle oil field in North Lincolnshire has upgraded reserves.

The study, published today by Union Jack, a partner in the field, reveals:

• 2P reserves (total proven and probable reserves) up 263%
• Reclassification of 1,883 thousand barrels of oil equivalent (mboe) in the Penistone Flags from contingent resources to 2P reserves
• Upgrade of 59% to the estimated ultimate reserves in the Ashover Grit and Wingfield Flags
• Upgrade of 23% to Broughton North prospective 2U resources (unrisked best estimate)

David Bramhill, Union Jack’s executive director said:

“The increase in Wressle’s Reserves vindicates the focus by the JV [joint venture] partners management of the field’s production to maximise recoverable volumes. This provides further support to the development approach we have undertaken to date.”

The study, known as a competent person’s report, or CPR, looked at two licence areas, PEDL180 and PEDL182, covering the Wressle and neighbouring fields.

The author, ERCE, reinterpreted reprocessed 3D seismic survey data and included production information and the results of well testing up to July 2023.

The CPR increased gross 2P reserves from 655mboe, estimated in 2016, to 2,373mboe. This included the reclassification of 1,883mboe to 2P reserves.  

The Broughton North prospect, in PEDL180, north west of Wressle, saw its 2U resources rise from 494mboe to 608mboe.

The Wressle operator, Egdon Resources, has confirmed it intends to submit plans to extend the site and add two new production wells, one of which would target gas.
