Jolokia 1 confirmed as the hottest EGS in the world
Jolokia 1 was drilled to 5000m and plugged almost exactly two years ago. A
GDY announcement at that time stated that they were expecting to find Jolokia
10 oC hotter than the Habanero wells. Geodynamics re-entered Jolokia-1
two months ago using the Rig 100 pictured below. The picture also shows the
7" completion casing on the rack ready to be run into the well..
Yesterday, Geodynamics provided a very positive update on Jolokia 1 reported
on the results of logging using an imaging tool. Reportedly, this is the first
time that an imaging tool has been successfully deployed to log a well bore
in the high temperature and high pressure conditions prevalent in the Cooper
Basin granite. Imaging was done to a depth of 4575 m. Logging results have revealed
potential fractures deeper within the granite at higher temperatures which are
believed to be comparable to the fractures photographed at 4575 m (see below).
The target is to generate a reservoir starting at 4900 m by stimulating and
enhancing these existing fracture network.
The logs also confirmed that the temperature at Jolokia is approximately 8
degrees hotter than the company’s Habanero site (at the same depth), making
Jolokia 1 the hottest EGS geothermal well in the world at this depth. Temperatures
in Jolokia at 4,900 m are around 278 °C. This confirms the 2008 expectations
quoted above. The hydraulic fracture stimulation program is now expected to
be completed during October -- slightly behind the schedule because of the delays
in inserting the liner and the heavy rains in the area but sill just in time
for the Australian Geothermal Energy
Conference on 10-13 November 2010, where Doone Wyborn of Geodynamics is
scheduled to present a paper on Jolokia-1 stimulation.
The good news made an immediate impact on the Geodynamics share price, which
lately has gone through some rough times as shown below.
