The Martlet North-1 exploration well, which is located on the western flank of South Australia’s Cooper basin, encountered oil shows in its primary target, the Namur Sandstone. Logs indicated the presence of 3.2 m of vertical net pay. Martlet also encountered oil in its secondary target, the Birkhead formation. The well has been cased and suspended as a future producer. Senex Energy (60%) is the operator with partner Beach Energy (40%).
