ChevronTexaco Corp. has confirmed that a production test in the Jansz gas field, 125 mi off the northwest coast of Western Australia, has demonstrated the field's extensive production potential. The Jansz-3 well, tested on July 2 in the WA-18-R permit area, flowed at 72 MMcf/d.
Operator Mobil Exploration and Producing Australia Pty. Ltd. appraised drilling on the Jansz field earlier this year, which indicated a field size of 760 sq mi with an interpreted 1,300 ft gross gas column. Including an extension of the Io-Jansz structure into the adjacent ChevronTexaco-operated WA-267-P block, it is estimated that the field contains 20 tcf of recoverable natural gas.
ChevronTexaco holds a 50% interest in the WA-18-R permit area, where the Jansz-3 well was drilled. ExxonMobil holds the remaining 50% equity interest. ChevronTexaco also holds a 50% interest in the adjacent WA-267-P block – where ExxonMobil holds 25%, Shell 12.5%, and BP 12.5% – which contains an extension of the Io-Jansz structure.
