Rich Resource Base Underpins Growth Strategy
ADX Energy (ASX:ADX) has unveiled an updated prospect inventory across its Upper Austria prospects by ADX Energy Ltd, highlighting multiple near-term and long-term growth opportunities. The company now boasts 24 drillable prospects with a total aggregated mean prospective resource estimate of 374 BCF (net) of gas and 31 MMBBL (net) of oil.
This substantial resource base spans across ADX's ADX-AT-I and ADX-AT-II permit areas, targeting five proven play types in the basin. The portfolio has been significantly enhanced since the company's previous update in June 2023, with eight new prospects added and four removed.
"The Prospect Inventory update reflects data obtained from drilling activities and our prospect maturation program utilising the extensive 3D seismic and data base available to ADX," explained Paul Fink, ADX Chief Executive.
Strategic Focus on Near-Term Production Opportunities
ADX's near-term exploration strategy is cleverly focused on two high-probability play types that could quickly translate to production and cash flow:
-
Shallow Gas Play – Low-cost, low-risk gas prospects where the first GOLD-1 well is scheduled for drilling in Q1 2026. This play leverages the recently varied ADX-AT-II license area.
-
Near Field Oil Play (Anshof) – Oil prospects adjacent to the company's existing Anshof field infrastructure, offering potential for accelerated high-value oil production. These prospects can utilize the Anshof field's 3,000 BPD production facility, significantly reducing development time and cost.
These opportunities are already advancing in the permitting phase, with ADX confirming that "three shallow gas targets and an Anshof near field oil target will be drillable within the next six months."
High-Impact Opportunities for Long-Term Growth
While the near-term focus is on lower-risk opportunities, ADX maintains substantial upside through several high-impact plays:
Welchau Carbonate Play
Following technical studies incorporating results from the Welchau-1 well drilled in March 2024, ADX has matured two significant prospects:
- Welchau Deep – A gas prospect with 125.4 BCF (Pmean, Gross) of prospective resources
- Rossberg – An oil prospect with 19.6 MMBBL (Pmean, Gross) of prospective resources
Notably, Welchau Deep could be accessed by deepening the existing Welchau-1 well, making it highly attractive from a risk-reward perspective.
Sub-Flysch Play
This under-explored area in the southern part of the ADX-AT-I permit includes four deeper gas prospects contributing a mean prospective resource of 252 BCF (Pmean, Gross) to the portfolio. An ongoing 3D seismic reprocessing program is expected to enhance and derisk this play.
Play Type Breakdown
The following table summarizes ADX's diverse prospect inventory by play type:
| Play Type | Gas Resource (BCF) Pmean, Net | Oil Resource (MMBBL) Pmean, Net | Key Prospects |
|---|---|---|---|
| Shallow Gas | 39.1 | – | GOLD, ZAUN, GRAB, HOCH |
| Near Field Oil (Anshof) | 4.3 | 14.3 | SGB, TERN, WOLF, PERG |
| Welchau Carbonate | 125.4 | 19.6 | Welchau Deep, Rossberg |
| Sub-Flysch | 251.8 | 1.8 | ZAM, OHO, IRR, GMU |
| Molasse | 18.5 | 0.9 | BRUNN, ARD, BUCH |
| TOTAL | 374 BCF | 31 MMBBL |
Understanding Prospective Resources
Prospective resources represent estimated quantities of petroleum that may potentially be recovered through future development projects. These estimates have both an associated risk of discovery and a risk of development. Further exploration, appraisal, and evaluation are required to determine the existence of significant quantities of potentially recoverable hydrocarbons.
In oil and gas exploration, resource estimates are typically presented with different probability scenarios:
- P90 (Low Estimate): At least a 90% probability that recovered quantities will equal or exceed this estimate
- P50 (Best Estimate): At least a 50% probability that recovered quantities will equal or exceed this estimate
- P10 (High Estimate): At least a 10% probability that recovered quantities will equal or exceed this estimate
Farmout Potential Enhances Strategic Flexibility
An important aspect of ADX's portfolio is the high equity interest held across many prospects, providing substantial leverage for potential farmout opportunities. This gives the company strategic flexibility in how it advances its higher-risk, higher-reward opportunities while maintaining focus on near-term production growth.
"These targets which are material and held at high equity interest also provide future farmout opportunities," noted Fink, highlighting the company's strategic options.
