Galilee Energy Finalises Zydeco-1 Well Design with Cost Savings, On Track for Q2 2026 Spud
Galilee Energy has completed the Zydeco-1 well design and directional plan, achieving around US$100,000 in cost savings and advancing steadily toward a Q2 2026 drilling start. The project targets Gulf Coast natural gas and condensate markets, supported by a newly appointed US Advisory Board.
- Zydeco-1 well design and directional plan completed
- Revised casing design delivers ~US$100,000 savings
- Authorization for Expenditure nearing finalisation
- Well on track to spud in Q2 2026
- US Advisory Board instrumental in project progress
Engineering Milestone Advances Zydeco-1 Toward Drilling
Galilee Energy (ASX:GLL) has reached a critical juncture in its US expansion, finalising the Zydeco-1 well design and directional drilling plan. This achievement not only de-risks the project technically but also delivers approximately US$100,000 in cost savings through a revised casing configuration. With engineering largely complete and the Authorization for Expenditure (AFE) close to finalisation, the well remains on schedule to spud in the second quarter of 2026.
Cost Discipline and Technical Precision
The updated casing design is a standout element, trimming tubular costs by about US$100,000 and promising further savings via reduced mud volumes and cuttings disposal. This reflects Galilee’s disciplined capital allocation as it moves from planning to execution. The Zydeco-1 well will reach an approximate depth of 9,750 feet, targeting multiple zones including the Tweedel reservoirs and Homeseeker B sand within a single borehole. The directional drilling plan has been optimised to ensure precise reservoir placement, enhancing the likelihood of a successful appraisal.
Strategic US Advisory Board Support
Galilee’s progress owes much to its US Advisory Board, a recently appointed group of seasoned oil and gas professionals who have helped refine the well design and execution strategy. This board, comprising experts such as Cleve Thomas and Dan Bloomer, has been pivotal in guiding asset selection and operational planning. Their involvement is a continuation of the company’s strategy to build a cash-flow driven US oil and gas business, as previously reported in the company’s US Advisory Board and Zydeco-1 Well update.
Exposure to Established US Energy Markets
Hydrocarbons from the Zydeco Gas Project in Louisiana will be sold into established Gulf Coast markets. Natural gas pricing is expected to reference the Henry Hub benchmark, while condensate and crude oil will align with West Texas Intermediate (WTI) or Louisiana Light Sweet (LLS) benchmarks. This linkage to widely recognised pricing points provides transparent market exposure and underpins the commercial viability of the project.
Operational Readiness and Next Steps
With the AFE nearing completion and final service quotes being secured, Galilee is advancing operational preparations including rig inspection and drilling program confirmation. Subject to final regulatory approvals, Zydeco-1 is set to spud in Q2 2026, marking a significant milestone in Galilee’s ambition to establish its first US production and build a broader Gulf Coast portfolio.
Bottom Line?
Galilee’s Zydeco-1 well design finalisation and cost savings sharpen its drill readiness, but regulatory approvals and final expenditure commitments remain key hurdles ahead.
Questions in the middle?
- Will regulatory approvals be secured in time to maintain the Q2 2026 spud schedule?
- How will the US Advisory Board influence operational decisions post-drilling?
- What are the prospects for expanding Galilee’s Gulf Coast footprint beyond Zydeco?
