Reckon Sheffield saw enough before signing over US$25m.

The Beetaloo’s ultra-dry gas nature (with <10% of frac water returning during early flowback) makes the first 24–48 hours of flow a much stronger indicator of likely IP30 than in wetter U.S. basins like the Marcellus.

• A strong first 24-hour gas rate in Beetaloo is much closer to true IP potential.
• If gas flows immediately and pressure holds, you’re seeing near-max productivity.
• Very limited transient phase compared to U.S. shale.

SS-1H Decline Chart

• IP30 Flow Rate (Normalised to 1,000 m / ~3,281 ft):

6.4 MMcf/d (Beetaloo Basin record at the time)

• Curve Profile:
  • Day 1: ~18–19 MMcf/d (strong initial surge),
  • Rapid early cleanup over first 2–3 days,
  • Stabilises around ~6 MMcf/d from Day 7 onward,
  • Flat tail from Day 10 to 30.
• Comparison Benchmark:
  • T3H: 5.2 MMcf/d IP30 (previous best Beetaloo well),
  • SS-1H clearly outperforms across the curve.
