TEST DATA FROM THE DISCOVERY WELL (Laminaria-1):RFT 1, 3,213 m,Recovered 750 cc fo 59 o API oil, 9 ccof water and 0.45 cubic feet ofgas.Production Test 1, 3,292-3,302 m,Flowed oil at 6,085 bbls/day and gas at253,000 m 3 /day through a 32/64” choke.Production Test 2, 3,213-3,240 m,Flowed oil at 5,826 bbls/day and gas at165,000 m 3 /day through a 32/64” choke.Production Test 3, 3,259.8-3,264.5 m,Flowed oil at 7,542 bbls/day and gas at106,000 m 3 /day through a 40/64” choke.Laminaria/Elang FormationLaminaria/Elang FormationLaminaria/Elang FormationLaminaria/Elang FormationAPPRAISAL AND DEVELOPMENT DRILLING :Laminaria-2, drilled 1.5 km east of Laminaria-1, intersected a 102 m oil column in the Elang/PloverFormation. A cased DST over the interval 3,285 – 3,300 mKB flowed oil at 6,650 bbls/day and gas at7,079 m 3 /day. The well was suspended as a potential oil producer in May 1995.Laminaria-3 was drilled 2 km south of Laminaria-1 to evaluate the most southerly fault block in theLaminaria structure. The well was deviated as Laminaria-3DW-1.Laminaria-3DW-1 was drilled to achieve a displacement of the bottom hole location of 1,000 m to 330 oin order to further evaluate the Laminaria reservoir. The deviated well intersected a 23 m gross oilcolumn.Laminaria-4 was located 200 m away from Laminaria-1. The well was cased and suspended as a futureoil producer after intersecting a 99 m gross oil column.Laminaria-5 was spudded in February 1998 and was sidetracked due to mechanical difficulties. Thewell was cased and suspended as a future oil producer after intersecting a 150 m gross oil column.Laminaria East-1 was drilled 3 km east of Laminaria-1 to test the eastern extension of the Laminariastructure within the adjacent permit (AC/P8). A DST over the interval 3,292.75 – 3,312.75 mKB flowedoil at 11,100 bbls/day and gas at 61,164 m 3 /day through a 20.6 mm choke.Laminaria-6 was spudded in January 1999 and completed as a future oil producer.Laminaria-7 and 8 were originally planned as horizontal wells to accelerate production and accessincremental reserves, but were redesigned as vertical producers after encountering drilling difficulties.RESERVES :Initial Oil : 119.5 MMbblsRemaining Oil: 64.6 MMbbls (at end 2001)Source: Northern Territory Department of Business Industry and ResourceDevelopment, 2002.
