| Abstract | Geodynamics drilled the Jolokia 1 well in 2008 to a depth of 4,911m in the Innamincka granite at a location 9.5km west of the Habanero EGS field in north eastern South Australia. The reservoir stimulation program was delayed until 2010. Initially the delay was related to the need to undertake further evaluation of the well and implementation of a technical solution to allow multi-fracture stimulation. The stimulation was further delayed when the casing in Habanero 3 well failed in April 2009. The aims of the stimulation are to: (i) Confirm the capacity to create heat exchange reservoirs at locations spread across the Innamincka granite resource. (ii) Develop two separate reservoirs in the one well, both deeper and hotter than the reservoir operated at the Habanero field (iii) Demonstrate injectivity increases compared to the Habanero field. |
