RFT 1, 2,301 m,Recovered 12.25 litres of water with atrace of mud.Plover FormationAPPRAISAL AND DEVELOPMENT DRILLING :Sunrise-2, located 15 km north-northwest of Sunrise-1, was drilled in May 1998 to appraise the northernlimit of the Sunrise gas/condensate accumulation. A 151 m gross gas column was identified on logs anda DST taken over the interval 2,112-2,124 mKB achieved a maximum flow rate of 849,500 m 3 /daythrough a 2” choke.RESERVES:Gas:Condensate:9.56 TCF (includes Loxton Shoals/Troubadour/Sunset/Sunset West)321 MMbbls (includes Loxton Shoals/Troubadour/Sunset/Sunset West)Source: Northern Territory Department of Business Industry and ResourceDevelopment, 2000.REMARKS:Two hydrocarbon bearing zones were identified on logs. The upper sand, (2,142-2,156 mKB) recordedwater saturations of around 25% while the lower zone, (2,195-2,206 mKB) averaged 35% watersaturation.Loxton Shoals-1, Troubadour-1, Sunset-1, Sunset West-1, Sunrise-1 and Sunrise-2 all recovered gas ontest from the Plover Formation from what are thought to be adjacent fault compartments on the greaterSunrise/Troubadour structure. Development of the Sunrise/Troubadour resource is currently underconsideration.STRATIGRAPHY (Sunrise-1) :AGE UNIT FORMATION TOP(mKB)QUATERNARY WOODBINE Undifferentiated 189.0TERTIARY GROUP Undifferentiated 492.5CRETACEOUS BATHURST ISLAND GP Undifferentiated 1472.0JURASSIC TROUGHTON GROUP Plover Formation 2096.5
