Woodside Completes Second Production Test on Pluto-1

Woodside reports that production testing of a second stratigraphic interval in the Pluto-1 exploration well in the Carnarvon Basin has been completed. The test was conducted over an interval of 28.6 meters in Tithonian aged sediments, comprising thin, gas-bearing sands, interpreted earlier from wireline log data. The test established a stabilized 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.

Analysis of the wireline log data reveals that the well has encountered net gas pay of approximately 111 meters 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 meters. No gas-water contact was intersected in the well; however, approximately 16 meters of additional gross gas column is inferred to be present from pressure data in the well.

The well is now being prepared for abandonment, as planned. Woodside Energy Ltd. has a 100% interest in WA-350-P.
