After identifying the best performing fluid, extensive compatibility testing was conducted to ensure that the RDF would work within the required drilling parameters, but without damaging the formation. This laboratory testing has informed not only the chemical makeup of the fluid but also the operating procedures to ensure the quality of the RDF is maintained throughout. A further impact on the performance of Alameda-2 is believed to be the physical configuration of the wellbore and its multi-target design. For development drilling, the well design was therefore significantly simplified to a single target with open-hole completion. Procurement and delivery receipt of all equipment and materials necessary to drill Amistad-2 and Amistad-3 was completed during the period. Construction of the Amistad-2 and Amistad-3 well pads was conducted and all necessary permits to drill were received during the period. The Amistad-2 well will be directionally drilled to target the Unit 1B approximately 200m up dip and 850m to the south of Alameda-2. This location is expected to intersect the axial crest of a localised anticline and due to the combination of geological structuring, in-situ stresses and brittle formation is expected to encounter a substantially fractured and productive reservoir section. Commencement of the Amistad drilling awaits the arrival of the drilling rig. The Amistad-2 and subsequent contingent Amistad-3 wells are planned to be completed prior to testing. This is to minimise the potential for formation damage. It also means that as soon as the rig is demobilised from the location, the well will commence production. For these initial wells, each well pad will have its own small production facility, tanks and tanker loading gantry with provision to upgrade and expand as required. Commercial arrangements have continued to progress through the course of the year. The Company has identified a reliable export pathway for its crude production, enabling early sales and an efficient route to market ahead of the Company establishing more significant volumes. This solution supports timely monetisation of production contributing to development funding. 09 Melbana Energy Limited Annual Report 2025
