Quadrant has cemented the liner to around 5,205 meters and is drilling ahead to target depth at the Phoenix South-3 well off north Western Australia.
Carnarvon Petroleum, which has a 20% interest in the Phoenix project with JV partner and operator Quadrant holding the 80% balance, announced that the GSF Development Driller-1 semi-submersible rig was drilling ahead to a depth of approximately 5,500m.
The previously drilled Phoenix South-2 well was unable to fully evaluate the Caley Member due to high pressures encountered in that well. The PS3 well plan and its associated procedures employ controlled drilling operations prior to and during the drilling of the reservoir section.
As a consequence, Carnarvon said drilling progress will be slower than that previously experienced in the other wells in the Phoenix project.
The primary objective for the Phoenix South-3 well is to evaluate the gas and condensate potential of the Caley Member within a large, faulted anti-clinal closure that was partially penetrated with the Phoenix South-2 well.
Phoenix South-2 encountered gas and condensate in the Caley Member but was unable to drill through and evaluate the formation. The Phoenix South-3 well has been optimally designed to penetrate and evaluate the hydrocarbon bearing formations of the Caley Member.
Phoenix South-3 is located around 560 metres north-north east of the Phoenix South-2 well. The well will target a closure that is estimated to contain a gross mean recoverable prospective resource of 489 Bscf of gas and 57 million barrels of associated condensate.
