Jabiru-4 intersected a 32.5 m gross oil column (22.5 m net pay). However production testing resulted inan oil flow of only 90 bbls/day and the well was plugged and abandoned.Jabiru-5A was sidetracked from Jabiru-5 and intersected a 37.3 m gross oil column within the Jurassic.Oil shows were noted between 1,206 mKB and 1,220 mKB towards the base of the Palaeocene and maybe evidence of oil leaked from the Jabiru structure as a result of Mio-Pliocene fault reactivation.Jabiru-6 was drilled to produce oil updip of Jabiru-3. The well intersected 60 m TVT of net oil sand andwas cased and suspended as an oil producer.Jabiru-7 intersected the base of the Cretaceous on the downthrown side of the major bounding fault.The well penetrated 6.9 m of net oil sand and was sidetracked (Jabiru-7ST-1)Jabiru-7ST-1 was sidetracked 130 m to the north at an angle of 53.7 o from the main vertical well(Jabiru-7). The sidetrack intersected 13.2 m TVT of net oil sand and was cased and suspended as an oilproducer.Jabiru-8 was plugged and abandoned after losing the bottom hole assembly.Jabiru-8A, (planned as a redrill of Jabiru-8), was sidetracked after encountering the Cretaceous andJurassic sections on the downthrown side of the main bounding fault.Jabiru-8AST-1 intersected a 45 m TVT net oil column after Jabiru-8 was plugged back and kicked offat 1,060 mKB. The sidetrack was subsequently cased and suspended as an oil producer.Jabiru-9 was plugged and abandoned after a fish became stuck in the hole.Jabiru-9ST-1 was sidetracked around the fish but was interpreted as having been drilled on thedownthrown side of the main bounding fault. The well was plugged back to 1,369 mKB and kicked offas Jabiru-9ST-2.Jabiru-9ST-2 was plugged back to 1,423 mKB and kicked off as Jabiru-9ST-3.Jabiru-9ST-3 intersected a 24 mTVT gross oil column (22 mTVT net pay) but was plugged andabandoned.Jabiru-10 was plugged and abandoned after intersecting a 21 m gross oil column in poor qualityreservoir. A residual oil/water contact was noted at 1,644 mSS.Jabiru-11 was designed as a directional hole to drain oil updip of Jabiru-5. An inability to build up thedeviation angle caused the well to be plugged back 1,210 mKB and kicked off as Jabiru-11ST-1.Jabiru-11ST-1 was cased and suspended as an oil producer.Jabiru-12 was plugged and abandoned after intersecting an 11 m gross oil column (10.3 m net pay).Jabiru-13 was plugged and abandoned dry but a deviated well (Jabiru-13DW-1) drilled from the samelocation was cased and suspended as an oil producer.
