Western Flank oil exploration success at September-1

Oilfield Technology,

Beach Energy Ltd has announced a Western Flank oil discovery within the Poolowanna Formation in ex PEL 91 (Beach 100%).


September-1 targeted oil in a structural closure within the Namur Sandstone and tested the McKinlay Member, Birkhead Formation and Poolowanna Formation as secondary targets. The well intersected an eight metre gross interval with oil shows within the Poolowanna Formation. A drill stem test was undertaken over the interval 1927.8 m to 1936.0 m and recovered 15.2 bbls of approximately 42 degree API oil from the drill string over a 1.5 hour flow period. The flow rate was calculated to be 210 bpd. September-1 has been cased and suspended as a future oil producer.


This discovery validates the Poolowanna Formation as an additional exploration target within the ex PEL 91 permit area. Review of results is currently underway and further production testing is planned to confirm the resource size. Further mapping of the Poolowanna oil play will be undertaken through FY17, with potential appraisal and near field exploration activities in FY18.

Beach’s CEO, Matt Kay, said “Beach has achieved two oil discoveries from the first two exploration wells of its FY17 operated drilling campaign. Importantly, discovery of oil in the Birkhead Formation at Kangaroo-1 and in the Poolowanna Formation at September-1 has proven additional play potential within PEL 91. This reinforces our confidence in the ongoing prospectivity of our Western Flank acreage.
