• Zydeco-1 well design and directional plan completed
• ~US$100,000 cost savings achieved through revised casing design
• US Advisory Board provides technical and operational expertise

Galilee Energy Limited (ASX: GLL) has provided an update on the Zydeco-1 well, with the company announcing the completion of the wellbore schematic and directional drilling plan. This represents a significant step in de-risking the well design and establishing a clear drilling program. The company has also implemented a revised casing configuration, delivering an estimated ~US$100,000 reduction in tubular costs, with additional savings expected through reduced mud volumes and cuttings disposal. This reflects Galilee's focus on disciplined capital allocation as it advances toward drilling. The company's US Advisory Board, comprised of experienced US oil and gas operators, technical experts and commercial advisors, has been instrumental in progressing Zydeco-1 to this advanced stage, with the well scheduled to spud in Q2 2026. The Advisory Board has guided asset selection, operational execution and the company's focus on capital efficiency. Zydeco-1 is designed as a multi-objective appraisal and production well, capable of testing and, if successful, completing both Tweedel reservoirs and the Homeseeker B sand within a single borehole. The Authorization for Expenditure (AFE) is well advanced and expected to be finalised shortly, with final service quotes currently being secured. Galilee is also progressing final operational preparations, including rig inspection and confirmation of the drilling program. The company remains on track to spud Zydeco-1 in Q2 2026, subject to final regulatory approvals, representing a key milestone in establishing initial production and advancing Galilee's US growth strategy.

Galilee Energy is targeting to become a mid-tier US Oil & Gas producer, commencing with the development of the Zydeco Gas Project in Louisiana, USA. The company is also the 100% owner of one of the largest uncontracted natural gas resources on the east coast of Australia, located within the Glenaras Gas Project in Queensland's Galilee Basin.
