Both tests demonstrated positive indications of high pressure at surface. In the case of the Alameda test, immediately upon firing the perforation guns there was positive indication of pressure at surface, which confirmed the perforations had been successful. The pressure then quickly built to 3034 PSI. Test gauges were opened on various choke sizes and shut in periods were performed to build pressure. However, minimal returns were achieved at surface from either test and the complete removal of drilling mud and downhole fluids from the test string not achieved: oil did not flow to surface. 13-3/8” Casing Shoe 7” liner Shoe Unit-3 Alameda-N Marti-I 4-1/2” Slotted Liner DST-1 Open Hole DST-2 Alameda N Sheet tested as a single zone with perforations opposite most likely highest productivity interval as indicated by wireline logs TD 3880mMD 9-5/8” Casing Shoe Figure 2: Positioning of the Alameda and Marti reservoirs where flow testing was undertaken at depth Figure 3: Depth of the Alameda and Marti reservoirs Directors’ Report continued 16 Melbana Energy Limited Annual Report 2024
