Update on production operations and 2025 well testing programme
LONDON, 29 September 2025: Petro Matad Limited, the AIM quoted Mongolian oil company, is pleased to provide the following update on its Heron-1 production operations and the 2025 well testing programme.
Heron-1 production operations
The Heron-1 well continues to produce with artificial lift at a rate of c. 150 barrels per day (bopd) with water cut stable at c. 3%. The well performance to date when compared to data the Company has for other wells in the basin indicates a pressure profile similar to some of the better producing wells in Block XIX. To date, data from Heron-1 does not show that any faults or reservoir boundaries have been encountered that limit reservoir volume. Trucking, offloading and transfer operations at the Block XIX TA-1 facilities continue to run smoothly.
Following interaction with the Customs authorities, they have determined that supporting export paperwork specific to Block XX crude is not required as the crude is mixed with Block XIX crude and exported to the buyer as a single product. This decision by Customs streamlines the bureaucracy considerably as it avoids the need to provide a certificate of origin and to do laboratory tests at the provincial testing facilities for each export shipment.
