Woodside Completes Stybarrow-4

Woodside, a participant in the BHP Billiton operated WA-255-P Joint Venture, reports that the Stybarrow-4 appraisal well located in the Exmouth Sub-basin is currently preparing to plug and abandon.

The well was drilled to a total depth of 2,500 meters, and wireline logs were run.

Preliminary analysis of the logs suggests that the well intersected approximately 11 meters of oil-bearing reservoir within the primary target Macedon member sandstone. The previously drilled Stybarrow-3 vertical well encountered approximately 2 meters of oil bearing sand in this reservoir interval.

The Atwood Eagle semisub is drilling the well. The well location is approximately 2 kilometers northeast of Stybarrow-1. Water depth at the location is approximately 790 meters.

On completion of the plugging and abandonment the rig will move to the Knott-1 well location, also in WA-255-P.

Equal joint venture participants in WA-255-P are BHP Billiton Petroleum (Australia) Pty. Ltd. and Woodside Energy Ltd.
