Commencement of IP30 Testing Falcon has announced the commencement of the 30-day initial production (IP30) testing at the Shenandoah South 1H well. Results of the IP30 test are expected by the end of February 2024. Falcon estimates that a IP30 rate of 1.5MMscf/d over the 500m horizontal section (3.0MMscf/d normalised over 1,000m) or greater will allow the JV to progress the sanctioning of the proposed 40MMscf/d pilot project at Shenandoah South during H1/24. - So Far, So Good: Following the completion of the 10-stage stimulation programme and the subsequent successful installation of production tubing, the SS1H well was opened to allow sufficient flow back of stimulation fluid ahead of commencing the IP30 test. As planned, the well was shut-in for a three-week soak period to allow for sufficient stimulation fluid to be absorbed by the shale, increasing the relative permeability to gas of the formation and enhancing future production performance. Soaking was effectively implemented at the Carpentaria-2H well in EP187, with flow rates increasing from 1.3MMscf/d (IP27, normalised over 1,000m) pre-soaking, to 3.0MMscf/d (IP30, normalised over 1,000m) post soaking. - Targeting Deeper Acreage with Higher Pressures: The SS1H well is targeting the Amungee Member B shale at an estimated depth of 3,200m (c30% or 700m deeper than the previously drilled Amungee2H well). The decision for the SS1H well location follows analysis of the Tanumbirini wells drilled in the Santos-operated EP161 permit, which showed Marcellus Basin production type-curves. The Tanumbirini-2H and 3H wells are the longest producing wells in the basin (>6 months) and initially produced at a normalised IP30 rate over 1,000 metres of 3.3MMscf/d and 5.2MMscf/d, respectively. Modelling of the Tanumbirini-2H and 3H wells has demonstrated a 20-year estimated ultimate recovery of 16.8-18.5Bcf, for a proposed 3,000m development well. These results are in-line with Tier 1 and Tier 2 wells in the Marcellus Basin, one of the world’s most prolific shale gas basins. - High Quality Shale, Optimal for Development: Results from the diagnostic fracture injection test (DFIT) of the Amungee Member B Shale have demonstrated an over pressured regime, with a pore pressure gradient of 0.54 psi per foot. This result is in-line with the core Marcellus Basin and exceeds the near normal pressures (0.48 psi per foot) encountered in the other Beetaloo wells drilled to date. The DFIT result, together with the other reservoir properties from the SS1H well closely resemble the US’ most prolific gas resource in the Marcellus Basin, giving increased confidence that the SS1H well can flow at a rate in excess of the commerciality threshold for the Beetaloo Basin. - 2024/2025 Pilot Development: Once sanctioned, an initial pilot development is expected to be composed of several wells drilled and fracked over 2024/2025 from the existing Shenandoah South well pad and a second pad nearby.
