The test was conducted over an interval of 28.6 metres in Tithonian aged sediments, comprising thin, gas-bearing sands, interpreted earlier from wireline log data. The test established a stabilised gas flow rate of 9.5 million standard cubic feet per day through a 28/64 inch choke.
“These results confirm the producibility of this poorer quality stratigraphic interval,” Woodside said in a statement.
“Analysis of the wireline log data reveals that the well has encountered net gas pay of approximately 111 metres in Triassic-Lower Jurassic Mungaroo and Brigadier Formations, and overlying Tithonian sediments.
“This represents a net-to-gross of approximately 53%, based on the intersected gross gas column of 209 metres.”
No gas-water contact was intersected in the well, but about 16 metres of additional gross gas column is inferred to be present from pressure data in the well.
Ealier this week, Woodside announced it had successfully tested another gas-bearing zone, conducting the test over a resstricted 10.5m interval within a 65.5m-thick gas sand.
Pluto-1 is now being prepared for abandonment, as planned.
Woodside Energy has a 100% interest in WA-350-P.
