Perth primarily based Carnarvon Petroleum and challenge operator Quadrant Energy, suggested that drilling of the nicely Phoenix South-Three commenced. Since arriving on web site, the Transocean semi-submersible GSF Development Driller I, efficiently accomplished the ‘able to function’ course of and has completed drilling the 42” gap in preparation to run floor casing. The 42” floor gap was drilled to round 240 metres MD in preparation for setting the 36” floor conductor. This conductor is barely deeper than Phoenix South-2 to accommodate heavier casing strings as allowed for on this nicely’s drill program. Following the setting of this conductor, the rig will drill the 26” gap, and set and cement the 20” casing. These operations are deliberate to take round 10 days to finish.
The main goal for the Phoenix South-Three nicely is to judge the gasoline and condensate potential of the Caley Member inside a big, faulted anti-clinal closure that was partially penetrated with the Phoenix South-2 nicely. Phoenix South-2 encountered gasoline and condensate within the Caley Member however was unable to drill via and consider the formation. The Phoenix South-Three nicely has been optimally designed to penetrate and consider the hydrocarbon bearing formations of the Caley Member. Phoenix South-Three is situated round 560 metres North-North East of the Phoenix South-2 nicely. The nicely will goal a closure that’s estimated by Carnarvon to include a gross imply recoverable potential useful resource of 489 Bscf of gasoline and 57 million barrels of related condensate (being 143 million barrels of oil equal. The nicely can be anticipated to come across sandstones inside the Hove Member that could be hydrocarbon bearing.
Drilling of the Phoenix South-Three nicely is estimated to take round 90 days to achieve the goal depth of roughly 5,500 m MD. The Operator’s plans embody staged drilling simply above and thru the Caley reservoir part. The result’s that drilling via the Caley reservoir part will progress slower than via the opposite sections of the nicely bore. (Source: Carnarvon Petroleum – Image: Quadrant Energy)
