Laminaria field
In October 1994, Laminaria-1 was drilled in exploration permit AC/P8 (subsequently converted to production license AC/L5) to test a tilted block on the Laminaria High.
The well intersected a 102 metre gross oil column within the Elang / Laminaria Formation. At date of writing, a further 9 appraisal / development wells had been drilled on the Laminaria structure, including one deviated well. The Laminaria oil field was found to extend into adjacent exploration permit WA-260-P (production license WA-18-L) and a unitisation agreement was finalised between the permittees of AC/P8 and WA-260-P in 1998.
In December 1995, Corallina-1 was drilled on a complex fault block, 10 kilometres northwest of Laminaria-1. The well flowed oil on test from the Elang / Laminaria Formation. Water depths increase from 300-400 metres over Laminaria, to 400-450 metres over Corallina.
A joint development of the Laminaria and Corallina oil discoveries was approved and in the initial development phase, 4 subsea completions at Laminaria and 2 production wells at Corallina were tied back to an FPSO (the Northern Endeavour) via flowlines.
One well has been dedicated to gas re-injection. The Northern Endeavour is permanently moored to an internal turret mooring system in a water depth of 385 metres, making it Australia’s deepest offshore oil production facility.
Production from Laminaria and Corallina commenced in November 1999. Phase two of the development was designed to accelerate production and access incremental reserves in the two fields. Laminaria-7 and Laminaria-8 were drilled during this phase and the wells flowed oil on test at 20,000 barrels/day and 50,000 barrels/day, respectively. (Laminaria-7 and Laminaria-8 were originally planned as horizontal wells but after encountering drilling difficulties, the wells were re-designed as vertical producers). Production from Laminaria-7and Laminaria-8 commenced in June 2002.
Initial, combined reserves of the Laminaria and Corallina oil fields have been estimated at 137.1 million barrels. The production life of the development has been estimated at 14 years (Northern Territory Department of Business, Industry and Resource Development, 2003).
