AWE Spuds Senecio-3 Appraisal Well in Permits L1/L2 in Perth Basin

AWE Limited, as Operator of Permits L1/L2 in the Perth Basin, Western Australia, announced Tuesday that the Senecio-3 appraisal well commenced drilling at 14:30 hours (02:30 pm) AWST on Monday, Aug. 4.

As at 06:00 hours (6.00am) AWST today, the well was at a measured depth of 1,752 feet (534 meters) and was drilling in a 12.25 inch hole to a planned depth of 3,789 feet (1,155 meters) in preparation for the installation of the 9.625 inch surface casing.

The Senecio-3 well will be drilled vertically to a planned total depth of 9,130 feet (2,783 meters) and is forecast to take approximately five weeks to complete. The well is designed to test the unconventional gas potential in the western side of the Senecio reservoir and is targeting the Dongara and Wagina tight sandstone formation. Core samples will be collected and sent for analysis and AWE will not conduct hydraulic fracture stimulation on Senecio-3 at this stage.

If the results are positive, AWE anticipates commencing the approvals process for the first phase of the Senecio unconventional gas field development. The Senecio-3 well could potentially be re-completed as a production well in a future field development.

The Senecio-3 appraisal well is located on agricultural land approximately 9 miles (14.5 kilometers) east of Dongara, Western Australia, and 4.3 miles (7 kilometers) from the operating Dongara gas plant.
