TEST DATA FROM THE DISCOVERY WELL (Rambler-1):DST 3 (CASED HOLE), 2,842-2,926 m,Recovered 17 bbls of water with an oilscum.DST 2 (CASED HOLE), 3,000-3,027 m,Recovered 0.5 bbls of water.Flamingo GroupFlamingo GroupRFT 1 (CASED HOLE), 3,018.5 m, Flamingo GroupRecovered 300 cc of medium green brown43 o API oil and 1.1 ft 3 of gas.DST (CASED HOLE) 1, 3,074-3,093 m,Tight. No recovery.RFT 2 (CASED HOLE), 3,082 m,Recovered 390 cc of medium green brown37 o API oil and 4.7 ft 3 of gas.Flamingo GroupFlamingo GroupREMARKS:A fracture intersected at 3,448 m within the lower Flamingo Group appears to have bled oil and gas intothe wellbore. However, the fracture is thought to be of limited extent or relatively impermeable, as thewell stabilised after kicking 50 bbls of mud.Geochemical analysis indicates that the oil bleeding from the fracture at 3,448 m is identical to the oilrecovered at 3,018.5 m and 3,082 m by RFT. It is thought that that gassy oil bleeding from the fractureat 3,448 m mixed with cement during the setting of casing and that the RFT tools subsequentlyrecovered oil from the oil impregnated cement.Log analysis indicates the presence of an 86 m gas column in low porosity and permeability sandstonesof the Upper Plover Formation. RFTs run near the top of the Plover Formation were either dry orrecorded very slow pressure buildups.STRATIGRAPHY (Rambler-1) :AGE UNIT FORMATION TOP(mKB)TERTIARY WOODBINE GROUP Undifferentiated 134.0BATHURST Vee Formation 1354.0CRETACEOUS ISLAND Wangarlu Formation 1581.0GROUP Radiolarite 2646.0Darwin Formation 2742.0FLAMINGO Undifferentiated 2774.0JURASSIC GROUP Cleia Shale 3504.0TROUGHTON GROUP Plover Formation 3595.0
