Project Profile
Value: US$1,200 million
Location: Block WA-356-P, Australia
Start-up Year: 2Q 2012, Balnaves to come onstream in 2014
Reserves: 2,118 billion ft³
Water Depth: 187m
Situated offshore Australia in WA-356-P in 614 feet (187 metres) of water is the Julimar gas field, which is operated by Woodside Energy, holding a 65% interest; Kufpec holds the remaining interest. The Julimar-1 well was drilled to a total depth of 12,221 feet (3,725 metres), discovering 132 feet (40 metres) of natural gas pay in the prolific Triassic Mungaroo formation. A production test was conducted on two zones, flowing a combined 85 MMcf/d, precluding the need for further testing of the well. Several months later, the Julimar East-1 appraisal well logged 224 feet (68 metres) of net gas pay in six sandstone reservoirs in the Triassic Mungaroo formation. Three of the six intersected pay zones in Julimar East-1 are stratigraphically equivalent to gas bearing reservoirs in the Julimar-1 well, which was suspended as a future production well.
A year later, another well was drilled; the Julimar Southeast-1 discovery on Australia\'s Northwest Shelf logged 195 feet (59 metres) of net pay across five intervals of the Triassic Mungaroo Sandstone. The well, about 2 miles (3 kilometres) from Julimar-1, was not tested, logging 132 feet (40 metres) of net pay. A fourth appraisal well, the Julimar Northwest-1 exploration well logged 43 feet (13 metres) of net pay in the J-17 Triassic Mungaroo sandstone. Currently, the field is being analysed on how to best develop it.
