Discover Habanero

We are currently in the middle of a field program at Habanero that has four key steps. The successful completion of Habanero 4 is the first of these.

Project Overview
The Innamincka Deeps Joint Venture ("Deeps") was formed in 2007 with the sole focus of developing and commercialising geothermal energy generation from Enhanced Geothermal Systems (EGS) from the Cooper Basin in South Australia.

Project Data
  • Some of the hottest known heat producing granite rocks with measured temperatures of 273-283°C at 4,911 metres (Jolokia 1)
  • Current reported inferred, indicated and measured geothermal resource of 59,200 PJ recoverable thermal energy ~7,000 PJ end user energy
  • Equivalent to electrical supply from ~16 trillion cubic feet of natural gas or ~750 million metric tonnes of thermal coal (40% eff)
  • Drilled 6 of the deepest, hottest EGS wells
  • Discovered and enhanced the most productive granite fracture system in the world
Wells to Date

Date Drilled Name Depth Temperature

2004 Habanero 2 4,459 m 244ºC
2008 Habanero 3 4,200 m 242ºC
2008 Jolokia 1 4,911 m 278ºC
2009 Savina 1 3,700 m Well suspended
2012 Habanero 4 4,204 m --

Current Status
 
The Joint Venture has completed the drilling of Habanero 4.  Habanero 4 is the first stage in a refocused field program for the Deeps EGS geothermal project. In drilling the well, we are seeking to reconnect with the reservoir that was created previously. We then plan to further stimulate and increase the areal extent of the existing reservoir from that single location. The reservoir performance information and test data collected will provide assist in further delineating the resource.
 
Key Project Milestones and Immediate Activities
  • Re-establish hot circulation loop with Habanero 1
  • Commission 1 MWe Habanero Pilot Plant
  • Extended reservoir and plant testing to establish performance and characteristics
