Woodside & Repsol Complete Exploration Program on Block 401d

Woodside Energy (Algeria) Pty Ltd, a wholly owned subsidiary of Woodside Energy Ltd., a participant in the Repsol YPF operated Rhourde Seghir block 401d (onshore Algeria) reports that the two well exploration program in the block has now been completed.

The Rhourde El Rouni Central-1 (RERC-1) onshore exploration well has been plugged and abandoned at a total depth of 3,269 meters after intersecting water saturated sands at the Triassic and Devonian reservoir targets.

The Saipem drilling rig National 110 AZ 5893 was released at midnight on June 18, 2004 and moved to the Rhourde El Rouni West-1 (RERW-1) location, which is approximately 9 kilometers southwest of RERC-1.

The RERW-1 well was spudded on July 1, 2004 and has been temporarily abandoned at a total depth of 3,310 meters after intersecting an oil bearing sandstone section at the Triassic TAGI reservoir target. Evaluation of the data is ongoing to plan future exploration work and assess whether the discovery is commercial or not.

All reported depths are referenced to rig rotary table.

The RERW-1 well is located approximately 15 kilometers northeast of the ROD oil development, and 25 kilometers south of the existing El Borma pipeline.

Woodside's current interest in block 401d is 26.25%. Other participants are Sonatrach (25.00%), Repsol YPF (Operator, 41.25%) and Partex Oil and Gas (7.50%).
