Oh god I hope it isn't Walyering….poor quality reservoir

"In 1971, Walyering-1 was drilled 130 km north of Perth to test an anticlinal feature

delineated by seismic surveys in the late 1960s (figures 14 and 15). Gas flows were
recorded from two sands within the Cattamarra Coal Measures. Walyering-2,
designed to test the northern extension of the anticline, encountered the same gas
bearing sands intersected in the discovery well. A further well (Walyering-3),
investigated the potential of uplifted fault blocks to the southeast. However the two
zones of interest proved to be water wet at this location. A deeper sand tested by this
well flowed gas at the rate of 17 000 m3/day.
The gas reservoirs at Walyering are poor quality. Porosities average around 9% and
permeabilities are low (93 md). A production licence was awarded and Walyering-1
was connected to the Dongara-Perth gas pipeline in March 1972. After rapid​

production and pressure declines, the well was shut in. (Jones, 1976)."
