ExxonMobil
world-class gas discovery in australia
Posted: 25 March 2003
Exxon Mobil Corporation announced that its subsidiary, Mobil Exploration
and Producing Australia Pty Ltd, confirmed that further exploratory
drilling on the Jansz field off the Northwest coast of Western Australia
has indicated the presence of a world-class gas resource.
The Jansz-2 well was drilled in late 2002 to determine the extent
of the Jansz-1 discovery made in 2000 in the WA-18-R exploration
permit, approximately 125 miles off the Western Australia coast
of Karratha. The Jansz-2 well was drilled in 4,430 feet of water
to a depth of approximately 10,800 feet below sea level.
The Jansz field covers an area in excess of 766 square miles and
has an interpreted 1,300-foot gross gas column. Including an extension
into the adjacent WA-267-P block, it is estimated that the field
contains approximately 20 trillion cubic feet of recoverable gas.
"ExxonMobil believes the Jansz field to be the largest gas
discovery ever in Australian waters, representing around 40 per
cent of the undeveloped, discovered gas resources in the deepwater
Carnarvon Basin," said Jon Thompson, president of ExxonMobil
Exploration Company.
"This discovery is a significant addition to ExxonMobil's
resource base, which now stands at 72 billion oil-equivalent barrels.
During the last 10 years, this base has grown by nearly 30 percent,
or more than 16 billion oil-equivalent barrels," Thompson said.
ExxonMobil holds a 50 per cent equity interest and is operator
of the WA-18-R permit. ChevronTexaco holds the remaining 50 per
cent equity interest. Equity in the adjacent WA-267-P block is ChevronTexaco
50 per cent (operator), ExxonMobil 25 per cent, Shell 12.5 per cent
and BP 12.5 per cent.
The joint venture plans to drill an appraisal well (Jansz-3) and
perform a production test in mid-2003, to further delineate the
resource.
Terms such as "resource" and "recoverable gas"
include quantities of discovered oil and gas that are not yet classified
as proved reserves but that we believe will ultimately be produced
in the future. (Newstream)
