Bass Basin (Australia)
Gas Projects in Development
Since 1998, CalEnergy has been actively involved in both exploration and production in the Bass Basin, located in the offshore waters of the Bass Strait between the southeastern tip of mainland Australia and the Australian island state of Tasmania.
CalEnergy has been pursuing a monetization of its assets in this area and has entered into a number of third-party agreements that has resulted in the farm out sale of an aggregate 13.5 percent of CalEnergy's interest in permit T/18P. CalEnergy retains a 5 percent interest in the permit.
CalEnergy and its joint venture partners have made two gas discoveries in the T/18P permit to date: White Ibis No. 1 (1998) and Trefoil No. 1 (2004).
An exploration/appraisal drilling campaign was completed in Q1 2010.
Trefoil No. 2 was a successful appraisal of the southern flank of the Trefoil Field and has better defined the gas water contacts in the field. The operator currently is integrating the results of the well and reassessing field volumetrics.
The Rockhopper No.1 exploration well and subsequent down dip sidetrack were successful in identifying hydrocarbons, both liquids rich gas and oil, in several sands within the primary objective. The commercial significance of this discovery currently is being assessed by the operator.
