And a good day to you, here is a short story about the biggest drilling rig currently working in Australia and the proud owner is Geodynamics an Australian owned company forging ahead with the latest technology regarding geothermal/ hot rock. The crews came from a variety of drilling companies from around Australia i.e. Century Resources, Ensign International, Precision Drilling International, Hunt Energy and some of the boys from the Eastern Well Group work over division. The rig boasts a Leteauno top drive with the cyber chair, iron roughneck auto slips !!!! The rig has great crews that have made a big pile of American steel work after a few IQ tests and a rig move recently with no incidents or equipment damage to Jolokia #1 in the Innamincka reserve. For a better understanding of the geothermal project go to the link above and all will be explained in great detail.
