Strike Energy and Talon Energy have commenced preliminary activities at the Walyering-5 well in the Perth Basin following encouraging initial production test results.
After experiencing some minor logistics delays, Walyering-5 has been rigged up for the initial clean-up, perforation and unloading of the well while the final equipment arrives on-site.
It is expected that the surge tank and separator will clear customs and quarantine in the Fremantle Port within the next one to two weeks.
These pieces of equipment are critical for the facilitation of the full testing program, as well as the accurate measurement of the condensate gas ratio.
Meanwhile, the initial testing results have been encouraging with the D-Sand only representing 35 per cent of the total net pay measured in the petrophysical evaluation of the Walyering-5 well.
The D-Sand has been perforated across a 12.6m interval, with wet-gas flowing and flaring through the by-pass.
It is estimated to have preliminary reservoir pressures of 4516 pounds per square inch (psi) with a flowing well pressure of 2184psi through a 24/64-inch choke, and the field gas samples measured with negligible CO2 (-1 per cent) and zero hydrogen sulfide (H2S).
Once the separator is installed and testing continues, the condensate gas ratio will be measured more accurately.
The Walyering appraisal project is a fast-to-market opportunity based on a conventional gas discovery in the Cattamarra Coal Measures.
In 2020, Strike Energy farmed out a 45 per cent non-operated interest in Walyering to Talon Petroleum Limited, for a $6 million free-carry in an appraisal well planned for CY21.
With the Walyering-6 permits now approved, civil works have commenced with drilling expected to begin in May 2022.
