The Marauder-1 exploration well is located in ex PEL 104, approximately 2 km north of Senex’s producing Growler and Spitfire oilfields. The well was identified from the Mollichuta 3D seismic survey and was designed to evaluate the production potential of the Birkhead formation. Marauder-1 encountered good oil shows within well developed Birkhead sands and evaluation of logs indicate net pay of up to 8.6 m within a 17.5 m gross oil column.
A drill stem test over the Birkhead formation (1744.2 - 1764.6 m) recovered 83.7 bbls of approximately 48 degree API oil. Oil flowed to surface after 79 min. and continued to flow for the full 184 min. period on a ½” choke. The flow rate was calculated to be 655 bpd, with no indications of formation water throughout the drill stem test.
The well will be cased and suspended and is expected to be placed on production in the coming months via a flowline to connect the well to existing infrastructure on producing western flank fields.
Senex’s Managing Director and CEO, Ian Davies, noted that the result demonstrated the material untapped potential remaining on the prolific western flank.
