BRX4Z Workover at Brockham
 

Angus Energy plc (AIM: ANGS) is pleased to announce that preparations for the planned workover of the BRX4Z well at the Brockham Oil Field ("Brockham") are well advanced.

• Rig secured for the planned BRX4Z workover at the Brockham Oil Field, in which Angus holds an 80% interest and is the operator, with mobilisation expected in early November 2026.
• All long-lead items required for the workover programme have been ordered.
• Workover operations are expected to take approximately three weeks and will include perforation and acidization of the Portland reservoir interval.
• Programme intended to bring suspended wellbore, BRX4Z, onto production in order to increase production and recovery from the Company's existing Brockham asset.

The Company has secured the rig for the workover programme and all long-lead items required for the operation have been ordered. The rig is currently deployed elsewhere and is expected to mobilise to Brockham in early November. Operations at BRX4Z are expected to take approximately three weeks to complete.

The workover is designed to bring BRX4Z on to production from the Portland reservoir. The planned operations will include perforating and acidizing the Portland reservoir interval before completing the well for production.

The BRX4Z workover is intended to provide an additional producing well at Brockham and increase production from the Portland reservoir. The programme forms part of the Company's strategy to maximise recovery and value from its existing operated asset base through targeted investment in existing wells and infrastructure.

The Company will provide a further update following commencement of operations and as the workover programme progresses.
