The Martlet-1 exploration well on the western flank of the South Australian Cooper-Eromanga Basin has encountered a Namur oil accumulation, Senex Energy Ltd. said in a press release.

The Martlet-1 exploration well is located in PEL 104, in which Senex has a 60% interest and Beach Energy Ltd. has a 40% interest. It is about 1.8 km (1.1 miles) southeast of the Warhawk-1 exploration well. The well was designed to evaluate the oil potential of the Namur sandstone within an interpreted four-way dip-closed structure.

Martlet-1 encountered good oil shows in the target reservoir, and subsequent evaluation of logs indicated net pay of up to 6 m (20 ft). The well is currently being cased and suspended and is expected to be placed on production in the next quarter.
