• Walyering-7 has intersected a high-quality conventional gas accumulation in an
additional compartment to the north-east of the Walyering gas field.
• A total of 23m of net gas pay with an average porosity of 16% has been measured.
• Multiple logs, mobility and reservoir pressures have been collected with individual
interval characteristics including:
o A Sand: 22m of net pay at an average porosity of 16%, 4,210 psia pressure
o D Sand: 1m of net pay at an average porosity of 15%, 4,835 psia pressure
Strike Energy Limited is pleased to provide an update on the Walyering-7
(W7) well which has intersected a high-quality conventional gas accumulation to the north-east
of the currently producing Walyering gas field within Production Licence L23 (100% net to
Strike) within the Perth Basin.
Walyering-7 intersected the primary sandstone reservoirs within the Cattamarra Coal Measures
that have been mapped throughout the Walyering gas field. Mud logs, logging while drilling
(LWD) logs, mobilities and reservoir pressures have been collected across these reservoirs. A
total of 23m of net gas pay at an average 16% porosity has been interpreted, where the intervals
identified as net pay are made up of blocks of high-quality reservoir within much larger gross
sections.
Additional zones of potential pay in other reservoirs have been identified but, due to the inability
for the sampling tool to reach total depth, remain subject to demonstrating gas flows during the
testing phase before a potential upgrade to additional net gas pay.
The Walyering-7 well, which remains to be flowed, will be tested through the Walyering gas
processing facility shortly after the departure of the Ensign 970 drilling rig. Productivity, gas
compositions and connected volumes will be assessed and will inform the planned update to
the Walyering gas field Reserves and Resources review being conducted by RISC. Subject to
successful flow testing, W7 will be permanently tied into the facility, and will support future gas
marketing activities.
About the Walyering-7 Appraisal Campaign
The W7 well was drilled from a surface location co-located with the Walyering gas processing
facility (Lat: 30° 42' 45.301" S, Long: 115° 28' 30.408" E) directionally to the east into a fault
compartment north-east of the producing Walyering-5 structure. The below photo shows the
proximity of the W7 surface location to the gas processing facility. (Note the photo also shows a
slickline unit opening unproduced reservoirs at W6 to prepare for flow testing through the facility
as at late May 2024, which has subsequently been successful).
